These artists did more than create glass objects — they sparked a movement, redefining glass as a medium for transformation, storytelling, and beauty. The sections that follow are not a complete list of today’s many gifted artists, but instead highlight early pioneers whose vision resonates with the spirit of Kusala Healing Arts and has helped shape Ryan’s healing and artistic path.

We begin with the core processes that define the field today: Hot Glass, Warm Glass, and Cold Glass. Each holds its own traditions and techniques, while sculptural forms often weave across all three — reflecting the diversity and creativity that continue to inspire the Studio Glass Movement.

Studio Glass Movement

The Studio Glass Movement began in the early 1960s and radically transformed the world of glassmaking. Until that time, working with glass was almost entirely confined to factories — large industrial settings where craftsmanship served function and form was bound to production. But a quiet revolution was about to change everything.

In 1962, at the Toledo Museum of Art, ceramics professor Harvey Littleton and engineer Dominick Labino led a small experimental workshop. Their goal was simple: to show that molten glass could be worked in a studio setting — not just in massive factories. With Labino’s custom-built furnace and Littleton’s belief in glass as a form of personal expression, the workshop proved what was once thought impossible: glass could belong to the artist. This moment sparked the beginning of the Studio Glass Movement, a movement rooted in three essential values:

  • Artistic Expression over Functionality – Shifting away from production and toward deeply personal, often sculptural, forms.

  • Hands-on Craftsmanship – Artists became the makers, involved in every step from idea to form.

  • Innovation and Experimentation – New tools, methods, and ideas pushed the boundaries of what glass could do.

As this new approach to glassmaking spread, it gathered momentum across the United States and eventually took root globally — encouraging artists in Europe, Japan, and beyond to develop their own studio-based practices.

Key artists of the Studio Glass Movement

  • Harvey Littleton — The movement’s founding voice and visionary educator.

  • Dominick Labino — A technical pioneer who gave artists the means to melt and shape glass independently.

  • Marvin Lipofsky — Known for his abstract sculptural forms and for introducing studio glass to the West Coast and Europe.

  • Fritz Dreisbach — An energetic educator who helped spread studio glass across the U.S., bringing performance and play into the hot shop.

  • Henry Halem — Founded Kent State’s glass program in 1969 and authored Glass Notes, a key text in the Studio Glass Movement.

  • Dale Chihuly — A student of Littleton’s whose bold, organic forms helped elevate glass into the world of contemporary fine art.

Hot Glass

Hot Glass involves shaping molten glass at temperatures above 2,000°F. Gathered from a furnace on the end of a blowpipe or punty, the material moves like honey and cools quickly, requiring artists to work in rhythm with time and heat. It is glass in its most fluid and elemental form — a dance of fire, breath, gravity, and gesture.

Hot Glass Techniques

  • Glassblowing – Inflating molten glass into a bubble using a blowpipe, then shaping it with tools, molds, and breath.

  • Hot Sculpting – Shaping and assembling molten glass directly by hand or with tools, often without blowing, to create more figurative or abstract forms.

  • Hot Casting – Pouring molten glass into molds to create solid forms, often used for architectural or sculptural pieces.

Many artists who train in hot glass go on to master all three core techniques, often weaving them together in unique and innovative ways. The artists highlighted below have each helped shape the language of hot glass, bringing their own distinct voices to the medium.

Hot Glass Artists

  • Dale Chihuly — Transformed glass into immersive public art through bold color, scale, and Venetian influence.

  • Lino Tagliapietra — Venetian maestro who merged Murano mastery with modern design, elevating glass to fine art.

  • Benjamin Moore — Brought European masters to the U.S. and gained recognition for luminous color fields of light and space.

  • William Morris — Known for sculptural glass inspired by ancient cultures, Morris created narrative works that evoke myth and ritual.

  • Dante Marioni — Celebrated for symmetry and precision, Marioni creates vessels of harmony and timeless technical refinement.

  • Preston Singletary — Tlingit artist who merges Indigenous storytelling with glass, bridging heritage and contemporary form.

Warm Glass

Warm Glass offers a slower rhythm than hot glass — one shaped by stillness, layering, and time. Using kilns to heat and form glass at lower temperatures, usually between 1,100°F and 1,500°F, artists can patiently explore the medium. In warm glass, subtlety takes precedence over speed, with an emphasis on surface, translucency, and the play of light and form.

Warm Glass Techniques

  • Fusing – Joining layers of glass together through heat, allowing for pattern, color interplay, and dimension.

  • Slumping – Heating glass until it softens and slumps into a mold, creating controlled curves or vessel shapes.

  • Pâte de Verre – Using crushed glass packed into molds, then fired at low temperatures for delicate, grainy textures.

  • Kiln Casting – Melting glass into a mold inside a kiln, often used for architectural or sculptural forms.

Kiln formed and Kiln cast Glass Artists

  • Stanislav Libenský & Jaroslava Brychtová — Pioneers of kiln-cast glass, they created monumental sculptural works that redefined the medium as fine art.

  • Klaus Moje — Pioneering kiln formed glass, Moje fused vibrant color creating painterly mosaics that shaped contemporary warm glass.

  • Bertil Vallien — Swedish master of sand-cast glass, celebrated for narrative boat forms and archetypal sculptural imagery.

  • Toots Zynsky — Inventor of filet-de-verre, Zynsky fuses glass threads into vessels alive with motion, color, and rhythmic energy.

  • Daniel Clayman — Creates large-scale kiln cast glass sculptures that poetically explore the interplay of form, light, and shadow.

  • Jessica Loughlin — Known for minimalism, Loughlin evokes horizons and silence, using light and opacity to invite reflection and stillness.

While warm glass begins in the heat of the kiln, its essence is found in patience, refinement, and quiet transformation. At Kusala Healing Arts, these same qualities guide our approach to healing — layered, spacious, and attuned to the subtle rhythms of inner change.

Cold Glass

Cold Glass refers to shaping, carving, or polishing glass after it has cooled. Unlike hot or warm techniques, it does not rely on heat but instead uses tools, machines, and hand methods to refine surface, form, and clarity.

This is where glass meets precision: edges are honed, surfaces ground smooth, and patterns etched. Coldworking is patient, tactile, and exacting — a slow conversation between the artist and the material.

Cold Glass Techniques

  • Cutting and Grinding – Using diamond wheels or hand tools to remove material and define shape..

  • Polishing – Smoothing glass to a glossy, transparent finish using increasingly fine abrasives

  • Engraving and Carving – Etching designs or textures into the surface for depth or imagery.

  • Sandblasting – Using high-pressure air and grit to frost or matte parts of the glass surface.

Many artists use coldworking to refine and finish hot- or kiln-formed pieces, while others embrace it as a primary mode of creation — sculpting crystal with the same dedication one might bring to granite or marble.

Cold Glass Artists and Sculptors

  • Christopher Ries — Working in optical crystal, Ries sculpts monumental polished forms that explore light and shifting visual perspectives.

  • Jon Kuhn — Known for precise geometric constructions, layering cut glass into radiant landscapes of light and contemplation.

  • Toshio Iezumi — Known for polished laminated glass sculptures that refract light into rhythmic waves of optical stillness.

Cold glass invites stillness, clarity, and discipline. It teaches us to move with patience, to refine with intention, and to reveal beauty through precision. In the healing arts, the same clarity arises through touch, presence, and time — qualities that shape both bodywork and art in equal measure.

The Transformative Power of the Healing Arts

Glass, like healing, is a practice of patience, resilience, and transformation. Just as artists shape molten or kiln-formed glass into new forms, we shape ourselves through self-inquiry and by applying what we learn in daily life.

For those wishing to explore this path further, our upcoming Educational Resources page will feature programs and opportunities for glass artists across the U.S. and beyond.

It will serve as both a place of discovery for those new to glass art and a source of growth for experienced makers.
