How do I clean moulded art deco glass?

Wash the glass gently in warm water using a mild, non-abrasive detergent. Avoid harsh scrubbing brushes that might scratch frosted or stained surfaces. Dry the piece immediately with a soft, lint-free cloth to prevent water spots from forming on the complex relief details.

Were these items meant for daily use?

Many objects served practical purposes on dressing tables, dining rooms, and desks. Perfume bottles held scents, while bowls and vases served functional roles in the home. Larger chargers and decorative figurines were primarily ornamental, designed to catch light and display the maker's sculptural skill.

How can I tell a 1920s piece from a later reproduction?

Examine the sharpness of the moulded details and the weight of the glass body. Period production typically exhibits crisp definition in the relief work and appropriate handling wear on the base. Consult the signatures and factory marks moulded or engraved into the glass surface, comparing them against documented examples from the era.

Why do some pieces change colour in the light?

Opalescent glass contains chemical agents that react to illumination by scattering specific light wavelengths. This creates the characteristic milky blue and amber shift unique to this type of production. Direct sunlight or spotlighting enhances this optical phenomenon, highlighting the three-dimensional depth of the moulded design.
