Glass art is a uniquely hybrid field within the visual arts, positioned at the intersection of science, craft, industry, and fine art. Emerging independently across ancient civilizations including Egypt, Mesopotamia, Rome, and China, glass was initially a rare, technically demanding, and resource-intensive material, closely associated with power, ritual, and prestige. Over centuries, innovations such as glassblowing, enameling, mosaic techniques, and stained glass expanded its expressive and architectural potential, allowing glass to function not only as ornament or luxury object, but as a medium capable of shaping space, light, and narrative.
