The Rise of Modernism in Czech Glass
Early Modernism, Cubism and Rondocubism, c. 1908–1925
Introduction: When Ornament Gave Way to Structure
At the beginning of the twentieth century, Bohemian glassmaking stood at a remarkable artistic crossroads. The organic elegance of Art Nouveau, with its flowing contours, botanical ornament and iridescent surfaces, was increasingly accompanied by a new fascination with geometry, structural clarity and abstraction.
This transformation formed part of a broader movement towards modern design across Europe. Artists and designers began reconsidering the relationship between form, ornament and function, exploring simplified silhouettes, balanced proportions and geometric compositions. For Bohemian glassmakers, already celebrated for their sophisticated cutting and engraving traditions, these developments offered new opportunities to explore the expressive qualities of glass through structure, light and material.
Within this evolving artistic environment, Czech Cubism emerged around 1911 as a particularly distinctive and radical movement. Inspired by developments in Paris, Czech architects and designers extended Cubist principles beyond painting into architecture, furniture, ceramics and decorative objects. Their ambition was not merely to introduce a new ornamental style, but to reconsider the fundamental relationship between form, material and space.
The transformation of Czech glass design was neither uniform nor confined to a single artistic movement. It developed through the interaction of avant-garde designers, progressive organisations such as Artěl, specialist schools and established glassmaking workshops whose craftsmanship helped shape the wider evolution of twentieth-century glass.
From Art Nouveau to Geometric Modernism
At the beginning of the twentieth century, Art Nouveau glass frequently celebrated the expressive qualities of molten material. Its designers drew inspiration from natural growth, organic movement and the irregular patterns of the botanical world.
At the Lötz glassworks in Klášterský Mlýn, for example, glassmakers developed sophisticated combinations of hot-shaped forms, coloured glass, trailing and combed threads, and iridescent finishes. The resulting surfaces appeared fluid and alive, often recalling flowers, vines, water or natural mineral formations.
Alongside these organic tendencies, a different approach to design was gaining prominence. Although the geometric simplicity of early modern design contrasted with the flowing, botanical ornament of Art Nouveau, both shared a desire to redefine artistic expression and craftsmanship.

Drawing on earlier traditions of structural clarity found in Neoclassicism and Biedermeier, geometric Modernism increasingly favoured simplified forms, balanced proportions and reduced ornamentation. These tendencies became increasingly visible in European decorative arts, including Bohemian glassmaking.
Glass offered particular possibilities for this new aesthetic. Its transparency, brilliance and capacity to reflect and refract light could be explored through carefully organised geometric surfaces, without relying upon elaborate decorative motifs. Traditional techniques such as cutting, grinding and polishing were particularly suited to this development.

Although Bohemian glassmakers had employed geometric cutting for centuries, modern designers began reconsidering how these techniques could shape the visual identity of an object. Rather than serving exclusively as decoration, geometric cutting could increasingly define the proportions, structure and optical character of the glass itself.
The work of designers such as Jan Kotěra and Rudolf Stockar illustrates this movement towards structural clarity. Their designs demonstrate how simplified silhouettes, precise cutting and carefully organised geometric elements could transform functional glassware into expressions of modern design.

This development, however, should not be confused with Czech Cubism. Geometric Modernism represented a broader artistic tendency, while Czech Cubism emerged as a distinct avant-garde movement with specific artistic theories and practitioners.
Nevertheless, these approaches shared an interest in the expressive possibilities of geometry and material. The emergence of Czech Cubist glass was therefore not an abrupt rejection of earlier traditions, but part of a continuing transformation in the artistic interpretation of Bohemian craftsmanship.
From Paris to Prague: The Emergence of Czech Cubism
Cubism emerged in Paris around 1907, principally through the work of Pablo Picasso and Georges Braque. Influenced by Paul Cézanne's structural approach to nature and encounters with African and other non-European artistic traditions, the movement challenged the conventional representation of objects from a single viewpoint.
Rather than simply reproducing visible appearances, Cubist painters investigated the underlying structure of objects, reorganising forms into intersecting geometric planes and allowing multiple perspectives to coexist.
This new understanding of form had profound implications for the applied arts. If a painted object could be fragmented and reconstructed, could a physical object itself embody similar principles?
For Czech designers, the answer was yes.
Unlike the predominantly pictorial development of early French Cubism, the Czech movement acquired a particularly ambitious architectural and material dimension. Emerging in Prague around 1911, it was initially associated with the idea ofNew Art.
Painters Emil Filla and Josef Čapek, sculptor Otto Gutfreund, and architects and designers including Pavel Janák, Josef Gočár, Josef Chochol and Vlastislav Hofman sought to redefine artistic expression through geometry and structural form.
Their approach made Czech Cubism one of the most distinctive contributions to early European Modernism, extending the principles of Cubist painting into architecture, furniture, ceramics, glass and other decorative objects.
The movement's theoretical foundations drew upon ideas connecting crystalline geometry with spirituality and the inner forces of matter. Certain theorists believed that conventional horizontal and vertical surfaces imposed a static order upon objects, while inclined planes and angular fragmentation could express movement, tension and creative energy.
These ideas became particularly important in Czech applied arts, where an object could be conceived not merely as a functional vessel but as a carefully organised geometric composition.
For Bohemian glassmaking, the relationship between crystalline structure, transparency and reflected light offered especially compelling possibilities. The angular facets of crystal, reflections across intersecting planes and carefully controlled contrasts between polished and matte surfaces provided a natural medium through which such artistic ideas could be explored.
The distinction between Art Nouveau and Cubist design therefore went beyond the contrast between curved and straight lines. In much Art Nouveau glass, decoration, surface treatment and organic silhouette worked together to create a unified composition. In Cubist design, the object's structure itself could become the principal expressive element. A diagonal plane, angular projection or faceted surface could communicate movement without relying upon naturalistic ornament.
These artistic differences did not imply a complete technological rupture. Art Nouveau glass could also be cut and engraved, while geometrically designed modern glass could still be blown into moulds. The transformation lay primarily in the reinterpretation of established techniques through a new artistic conception.
The movement's theoretical foundations were further examined by art historian and collector Vincenc Kramář (1877–1960), whose influential monographKubismus, published in 1921, contributed to the scholarly interpretation of Cubism within Czech art.
Artěl: Bringing Avant-Garde Design into Everyday Life
Founded in Prague in 1908, Artěl became one of the most important organisations in the development of modern Czech applied art.
The cooperative brought together progressive designers and skilled craftspeople committed to improving the artistic quality of everyday objects. Influenced by the European Arts and Crafts movement and organisations such as the Wiener Werkstätte, Artěl sought to establish closer relationships between artistic design, craftsmanship and domestic life.
Its activities encompassed ceramics, glass, metalwork, wood, textiles and interior design.
During the years preceding the First World War, Artěl became strongly associated with Czech Cubism. Among the designers connected with its development werePavel Janák, Vlastislav Hofman, Josef Rosípal and Rudolf Stockar, each contributing to the broader transformation of Czech applied arts.
Their roles, however, were not identical.
Janák provided an important theoretical foundation for the movement, while Hofman explored its application across various materials, including glass. Rosípal became particularly notable for geometric drinking services incorporating coloured overlays and precise cutting. Stockar contributed to the broader development of modern glass design through functional objects characterised by carefully considered forms and geometric decoration.
Artěl's significance lay in its ability to connect artistic experimentation with practical production. Designers conceived objects whose manufacture depended upon the technical expertise of specialised Bohemian workshops. Glassblowing, cutting, engraving and polishing were therefore not abandoned in favour of modern design. Instead, these established techniques were employed to realise new aesthetic ambitions.
Artěl's production encompassed several stylistic tendencies, from late Art Nouveau to Cubism and, subsequently, Art Deco. Its importance was not limited to a single movement, but lay in bringing modern artistic thinking into everyday life.
The Crystalline Ideal: Pavel Janák and the Architecture of Form
Pavel Janák (1882–1956), a prominent Czech architect, designer and theorist, was one of the leading figures of Czech Cubism. In his influential 1911 essayHranol a pyramida(The Prism and the Pyramid), he explored the relationship between geometry, matter and spiritual expression, viewing crystalline structures and inclined planes as manifestations of dynamic forces.
Inspired by natural crystals, historical architecture and Cubist art, Janák believed that geometric form could express movement and energy without relying upon applied ornament. His ideas influenced Czech architecture and applied arts, particularly through his involvement with the Artěl Cooperative.
Although primarily associated with architecture and ceramics, Janák's theories provide an important conceptual foundation for understanding the fascination with faceted surfaces, crystalline geometry and the interplay of light in modern Czech glass design.

Rudolf Stockar: The Emergence of Geometric Glass Design
Rudolf Stockar (1886–1957) was a Czech architect and designer associated with Artěl whose glassworks illustrate the transition towards geometric modernism.
Among his documented designs are afaceted perfume bottle with a stopper (c. 1910) or footed glass bowl (c. 1914), both preserved in the Museum of Decorative Arts in Prague. The perfume bottle is particularly revealing. Its angular body is organised through sharply intersecting cut surfaces, while the pyramidal stopper reinforces its crystalline appearance.
Rather than relying upon applied floral ornament, the design draws its visual character from the structure and optical qualities of the glass itself. The cutting creates a succession of geometric planes that reflect and refract light, giving the compact vessel a pronounced sculptural quality. Stockar also explored geometry through the silhouettes of functional glass objects, including footed bowls with angular profiles and patterned edges. These works demonstrate how traditional glass-cutting techniques could be employed to create objects characterised by structural clarity and modern proportions.
Although some of Stockar's early designs predate the principal development of Czech Cubism, they reflect the growing fascination with crystalline geometry that would become central to the movement. His work therefore represents an important connection between early geometric modernism and the more explicitly Cubist glass designs of the following years.

The Technical Transformation: Cutting, Engraving and Geometric Form
To understand the emergence of geometric Modernism and Czech Cubism in Bohemian glassmaking, it is essential to examine the traditional manufacturing techniques through which these new artistic approaches were realised.
The techniques themselves were not new. Bohemian glassmakers had long mastered glassblowing, mould-blowing, cutting, engraving and polishing. What modern design introduced was an opportunity to reinterpret these established skills through a different understanding of form and structure.
Glassblowing and the Preparation of the Blank
Many cut-glass objects begin as blown or mould-blown blanks. The glassmaker gathers molten glass and shapes it using a blowpipe, tools and, where necessary, a mould. The initial form must accommodate subsequent cutting, which may significantly alter the object's final silhouette and surface.
For designs requiring pronounced geometric facets, the blank must contain sufficient material to allow controlled removal of glass. Wall thickness, cooling and the intended distribution of cuts therefore become essential considerations in translating the designer's concept into a finished object.
Facet-Cutting: Broušení skla
Glass cutting involves removing material from a cooled object using rotating grinding wheels and abrasives. The initial grinding establishes the required surfaces and patterns. Further stages employ progressively finer abrasives and polishing methods to achieve the intended finish. The technique can produce flat facets, grooves, intersecting planes and complex geometric arrangements.
In modern geometric glass design, cutting could become more than surface decoration. It could define the object's visual structure. The position, depth and orientation of individual cuts determine how light interacts with the glass, creating contrasts between transparent surfaces, reflected highlights and areas of optical distortion. Deep or closely intersecting cuts require particular precision because excessive material removal can weaken the vessel.

Wheel Engraving: Precision and Detail
Wheel engraving traditionally employs smaller rotating wheels, often made from copper and supplied with abrasive material, to remove glass with considerable control. This technique allows the creation of fine lines, inscriptions, figurative decoration and intricate patterns.
Although engraving remained important throughout the modern period, the most characteristic geometric effects visible in early Czech Cubist drinking services were often achieved through broader cutting rather than detailed pictorial engraving. The distinction is important because different techniques produce different optical and decorative results.
Polishing, Matte Surfaces and Optical Contrast
The final finish strongly influences the appearance of a glass object. A polished facet provides clear reflections and transparency, while a ground or matte surface scatters light and appears comparatively diffuse. Combining these finishes creates subtle contrasts between transparent and translucent areas, strengthening the distinction between adjacent surfaces.
In geometric modernist and Cubist glass, these effects could reinforce the architectural organisation of the object. The essential innovation was therefore not the invention of new cutting tools, but the reconsideration of what traditional Bohemian techniques could express.
Vlastislav Hofman: Cubist Geometry in Clear Glass
Vlastislav Hofman (1884–1964) was among the most experimental designers associated with Czech Cubism. His work extended across architecture, furniture, stage design and applied arts, including glassware produced through his association with Artěl.
A documented example is hisLiqueur Set, designed in 1911 for Artěl and attributed in published catalogues to the Arnošt Pryl Glassworks in Růženín near Chocerady, Bohemia. The set comprises a tapering decanter with a stopper and matching drinking glasses, made from clear, cut and matte-finished glass. Its design demonstrates how a relatively restrained geometric vocabulary could transform traditional functional glassware. The decanter's widening body is divided by carefully organised cuts, producing a rhythmic arrangement of geometric surfaces. The matching glasses echo this approach through balanced proportions and cut decoration.
Unlike the coloured overlays employed in some of Rosípal's designs, Hofman's set relies primarily upon the interaction between clear glass, geometric cutting and contrasting surface finishes. The result is an elegant composition in which the physical structure of the vessel becomes the principal decorative element.
Hofman's work demonstrates an important characteristic of early Czech Cubist glass design: the movement did not always require dramatic fragmentation or highly irregular silhouettes. It could also express its artistic ambitions through controlled geometry, proportion and the relationship between solid form and light.

Josef Rosípal: The Geometry of Functional Glass
Josef Rosípal (1884–1918) was an important figure in early Czech Cubist glass design, demonstrating how traditional Bohemian glassmaking techniques could be reinterpreted through modern geometric principles. His designs combined functional elegance with precise cutting, angular forms and striking contrasts between colour and transparency.
A notable example is hisLiquor Set (1913), preserved in the collection of the Museum of Decorative Arts in Prague. Comprising a tall, tapering carafe with a faceted stopper and matching drinking glasses, the set demonstrates Rosípal's innovative approach to geometric decoration while retaining the functionality of traditional glassware. The set employsoverlay glass (přejímané sklo) combined with cut-to-clear decoration, established techniques in Bohemian glassmaking. A layer of blue glass was applied over a clear glass body, after which skilled glass cutters carefully ground through selected areas of the coloured layer to reveal the transparent glass beneath.
This process created elongated, sharply defined geometric patterns and a striking contrast between deep blue and clear crystal. The interaction of precisely cut facets, transparency and colour enhances the reflection and refraction of light, giving the vessels a sense of depth, rhythm and architectural structure.
Rosípal's designs demonstrate how established craftsmanship could be transformed into a distinctive expression of Czech Cubism, where geometry became an integral part of the object's artistic identity rather than merely applied ornament. His work also illustrates the importance of collaboration between designers and specialist Bohemian glasshouses, whose practical knowledge made technically demanding geometric compositions possible.

Josef Hoffmann: The Modernist Language of Glass
Alongside the development of Czech Cubism, Bohemian glassmaking was influenced by the wider artistic innovations of Viennese Modernism. Among its leading figures was Josef Hoffmann (1870–1956), an Austrian architect and designer born in Brtnice, Moravia, and co-founder of the Wiener Werkstätte. His designs emphasised geometric clarity, refined proportions and the integration of artistic expression with skilled craftsmanship. Glass objects designed by Hoffmann and produced by Bohemian manufacturers, including works attributed to Meyr's Neffe, demonstrate the close relationship between Viennese artistic innovation and Bohemian glassmaking during the early twentieth century.

Bohemian Glasshouses and the Wider Development of Geometric Modernism
While Artěl and its designers played an important role in introducing avant-garde ideas into functional glassware, the broader Bohemian glass industry followed several overlapping paths towards modern design.
Established manufacturers were not necessarily participants in the original Czech Cubist movement. Nevertheless, their technical expertise and commercial development formed an essential part of the industrial environment in which geometric modernism emerged.
The distinction between direct Cubist production and the broader modernisation of glassmaking is particularly important when examining firms such as J. & L. Lobmeyr, Moser and Rückl.
J. & L. Lobmeyr: Modern Design and Bohemian Craftsmanship
The history of J. & L. Lobmeyr demonstrates the close relationship between Viennese design culture and the specialised glassmaking industries of North Bohemia. Although headquartered in Vienna, the firm maintained important connections with Kamenický Šenov, historically known as Steinschönau, a major centre of glass cutting and engraving.
Under the leadership of Stefan Rath (1876–1960), Lobmeyr became closely associated with modern design through collaborations with Josef Hoffmann, Adolf Loos and artists connected with the Wiener Werkstätte. A significant development occurred in 1918, when Rath established the companyLobmeyr's Neffe Stefan Rathin Kamenický Šenov, employing specialist engravers from the region. The resulting work combined progressive design with the area's established traditions of cutting and engraving, allowing sophisticated decorative and optical effects to be achieved through exceptional craftsmanship.

Lobmeyr's development belonged primarily to Viennese Modernism and the subsequent emergence of Art Deco, rather than the original Czech Cubist movement. Nevertheless, its activities illustrate how Bohemian craftsmanship supported the wider transformation of European glass design during the early twentieth century.
Meyr's Neffe: Bohemian Glassmaking and Viennese Modernism
Meyr's Neffe was one of the important artistic glass manufacturers of nineteenth- and early twentieth-century Bohemia. Established in 1816 in Adolfov, near Vimperk in South Bohemia, the glassworks developed a reputation for refined craftsmanship and the production of high-quality decorative glass. Its name, meaningMeyr's Nephew, reflected its origins within the Meyr glassmaking family and its subsequent management by the Kralik family.
At the beginning of the twentieth century, Meyr's Neffe played an important role in translating the artistic ideas of Viennese Modernism into glass. The factory collaborated with designers including Josef Hoffmann and Otto Prutscher, producing objects associated with the Vienna Secession and Wiener Werkstätte. These designs frequently incorporated simplified forms, geometric ornament, coloured overlays and precise cutting, combining the technical expertise of Bohemian glassmakers with the progressive artistic principles emerging in Vienna.
An important example is Otto Prutscher's wine goblet of approximately 1907, manufactured by Meyr's Neffe for the Viennese retailer E. Bakalowits Söhne. Its cobalt-blue geometric decoration and repeated square motifs illustrate the growing emphasis on structured ornament and geometric clarity before the emergence of Czech Cubism, (as illustrated in the third photograph above). Related designs, including Prutscher's confectionery bowl of approximately 1908, (as illustrated in the fourth photograph above), demonstrate how traditional Bohemian glassmaking techniques were adapted to new approaches to form, colour and decoration.
Despite the similarity in their names,Meyr's Neffe should not be confused with Lobmeyr's Neffe Stefan Rath, the glass-decorating enterprise established in Kamenický Šenov in 1918. Meyr's Neffe was an independent glass manufacturer based in South Bohemia, while Lobmeyr's Neffe Stefan Rath was connected with the Viennese firm J. & L. Lobmeyr and specialised particularly in cutting and engraving in North Bohemia. Although distinct enterprises, Meyr's Neffe also produced glass for J. & L. Lobmeyr, illustrating the interconnected nature of Viennese design and Bohemian glass manufacture.

In 1922, Meyr's Neffe was acquired by Moser, marking a further development in the consolidation of Bohemian glassmaking. Its earlier achievements nevertheless remain significant within the history of European Modernism, demonstrating how innovative design and established craftsmanship contributed to the transformation of decorative glass before and alongside the development of Czech Cubism.
Moser: From Art Nouveau Ornament to Architectural Crystal
Founded in Karlovy Vary in 1857 by Ludwig Moser, the company established an international reputation for finely engraved and decorated glass. At the beginning of the twentieth century, its production included elaborate Art Nouveau designs characterised by floral ornament, refined engraving and sophisticated colouring.
The company's development increasingly reflected the influence of Ludwig Moser's son, Leo Moser (1879–1974). Appointed technical director in 1908, Leo Moser explored the artistic possibilities of coloured crystal, cutting and new approaches to glass design. Following his father's death in 1916, he assumed greater responsibility for the company's artistic direction.
While exploring new approaches to glass design, Moser continued to produce decorative glassware rooted in historical traditions. Its celebratedSplendiddrinking service, introduced in 1911, exemplified the company's Neoclassical craftsmanship, illustrating how traditional luxury glassmaking coexisted with emerging Modernist experimentation.
An important development was the introduction of thick-walled coloured glass, whose material depth and precisely cut surfaces offered new optical possibilities. Broad facets and carefully organised geometric forms allowed colour and light to become increasingly important elements of the composition.
Leo Moser also pursued innovations in glass chemistry, developing distinctive colours that would become particularly significant during the interwar period.
Although these developments reflected a broader movement towards modern design, Moser's geometric glass should not automatically be classified as Czech Cubist. Its significance lies in the combination of technical innovation, artistic experimentation and craftsmanship that would later contribute to the company's important role in Art Deco glass.

Rückl: The Tradition of Cut Crystal
The Rückl family represents another important chapter in the industrial history of Bohemian cut crystal. Its glassmaking activities date to the nineteenth century, while Antonín Rückl established the family's Nižbor glassworks in 1903. The factory developed within an established tradition of glass manufacture, cutting and finishing.
These processes required close coordination between the glassmaker and the cutting workshop. The original vessel had to accommodate the intended decoration, while the precise removal of material determined the final arrangement of facets and the optical qualities of the finished object. Such craftsmanship provided the technical foundation for increasingly sophisticated geometric glass designs.
Although Rückl was operating during the Czech Cubist period, its direct involvement in the production of Artěl's early Cubist designs is not established by the sources considered here. Its importance in this historical context therefore lies primarily in its contribution to Bohemian cut-glass manufacture and the wider industrial development that would flourish during the interwar decades.

From Czech Cubism to Rondocubism: A New National Identity
The outbreak of the First World War in 1914 disrupted the experimental artistic environment in which Czech Cubism had emerged. However, its influence did not disappear.
The establishment of Czechoslovakia in 1918 created new circumstances for artistic and cultural development, encouraging designers to explore forms capable of expressing the identity of the newly independent state.
During the early 1920s, a distinctive approach known as theNational Style, orRondocubism, developed particularly in architecture and applied arts. Associated with designers including Pavel Janák and Josef Gočár, Rondocubism departed from the sharply fragmented geometry of pre-war Cubism.
Instead, it introduced rounded forms, circles, arches, decorative rhythms and vivid colour combinations, often drawing upon references to Czech and Slavic folk traditions. This development reflected changing artistic priorities. Where pre-war Cubism had explored the dynamic fragmentation of form, Rondocubism sought a more decorative and recognisably national artistic language. Its strongest documented expressions appeared in architecture, furniture and interior design.

For glassmaking, the connection is more complex. The early 1920s witnessed continuing experimentation with geometric cutting, coloured glass and decorative form, but these developments cannot all be attributed directly to Rondocubism.
It is therefore more accurate to understand Rondocubism as part of the broader transformation of Czech applied arts than to regard it as a dominant, clearly defined style of Bohemian glass production. Nevertheless, the movement provides an important historical bridge between the avant-garde experiments of the pre-war period and the decorative sophistication of the following decades.

Towards Art Deco: The Continuing Transformation
During the 1920s and 1930s, Bohemian glassmaking entered a period of artistic and industrial development shaped by international demand, technical refinement and changing ideas of modern luxury. Geometric decoration remained important, but its visual language evolved.
Where early Czech Cubism emphasised structural tension and crystalline fragmentation, interwar decorative glass increasingly explored symmetry, colour, stylised ornament and carefully balanced geometric compositions. The Art Deco movement brought these tendencies into a new international context.
Established glasshouses developed sophisticated combinations of cutting, engraving, coloured overlays and decorative finishes. Moser's experiments with coloured crystal became particularly significant, while other manufacturers and workshops contributed to the growing international reputation of Bohemian decorative glass. The geometric designs associated with firms such as Karl Palda would later become notable examples of this interwar aesthetic.

At the same time, glass artists explored the possibilities of engraving and sculptural expression, extending the artistic ambitions of the medium beyond conventional ornament. The work of Josef Drahoňovský (1877–1938), whose practice encompassed sculpture, gemstone engraving and glass decoration, belongs to this broader interwar development.
These artistic achievements did not emerge directly from Czech Cubism alone. They reflected a complex combination of historical craftsmanship, technical innovation, international influences and changing commercial tastes. Yet the modernist reconsideration of form that had characterised the early twentieth century remained an important part of their artistic inheritance.
Conclusion: The Enduring Power of Form
The rise of Modernism in Czech glass represented a profound transformation in the relationship between artistic imagination, material and craftsmanship. Moving beyond the organic ornament of Art Nouveau, Early Modernism introduced a growing emphasis on simplified forms, balanced proportions and geometric clarity, encouraging designers to explore new ways of expressing the inherent qualities of glass.
Within this evolving artistic environment, Czech Cubism offered a more radical interpretation of form. Inspired by the revolutionary ideas of Cubist painting, architects and designers extended its principles into furniture, ceramics, glass and other decorative arts, exploring angular planes, crystalline structures and the dynamic relationship between form and space. The established techniques of Bohemian glassmaking, particularly cutting, engraving and polishing, provided the means through which these artistic ambitions could be realised.
Following the establishment of Czechoslovakia in 1918, Rondocubism introduced another distinctive direction, replacing much of the sharp fragmentation of earlier Cubism with rounded forms, decorative rhythms and references to national identity. Although its direct expression in glassmaking was more limited, it formed an important part of the wider artistic transformation of Czech applied arts.
These developments were neither isolated nor strictly sequential. Early Modernism, Cubism and Rondocubism reflected different yet interconnected approaches to design, each contributing to a broader reconsideration of ornament, structure and artistic expression. Their significance lay not in abandoning the exceptional traditions of Bohemian craftsmanship, but in discovering new possibilities within them.
In Part 7 ofLegacy in Light: The Story of Czech Glass, we will turn to the Art Deco period, exploring how Czech glassmakers embraced sophisticated geometry, rich colours and innovative decorative techniques to create some of the most distinctive glass designs of the interwar years.
