Cameo glass is a form created by fusing two or more distinct layers of coloured glass together before carving or acid-etching the outer layer away. This process leaves a raised design that contrasts sharply with the background colour. Makers utilised this technique extensively to render naturalistic flower heads, stems, and aquatic scenes with genuine sculptural depth and shading.

How do I care for these glass pieces?

These items require gentle handling, particularly those featuring delicate gold leaf, enamel work, or mixed metal mounts. Dust them regularly with a soft, dry cloth rather than using chemical cleaning solutions. Keep them away from direct, harsh sunlight to preserve the richness of the red tones and prevent any degradation of applied surface decoration.

Are these pieces signed?

Many of the glass vessels and perfume bottles bear signature marks, either cameo-etched into the body or painted on the surface by the maker or workshop. These signatures authenticate the origin and provide clues about the specific period of manufacture. Unsigned pieces still display stylistic traits and techniques typical of particular workshops, though marked examples carry clearer attribution.

How do I distinguish art nouveau from art deco?

Art nouveau design relies on flowing, asymmetrical lines inspired by natural organic forms like plants, vines, and flowers. The aesthetic prioritizes curves and biological movement over rigid geometry. Art deco, which emerged later, favours symmetrical arrangements, streamlined silhouettes, and sharp angular patterns. The glass from the earlier period feels more fluid and botanical.
