How do I identify authentic Lalique glass?

Authentic pieces usually bear moulded, engraved, or sandblasted signatures appropriate to their production period. Look for crisp details in the relief work and distinct opalescent fire. Fakes often lack the weight, precise proportions, and optical depth found in genuine twentieth century French works.

Cameo glass is formed by fusing layers of different coloured glass together before carving or acid etching the outer layer away. This leaves a contrasting raised design. Master glassmakers utilised this laborious technique during the Art Nouveau period to depict natural scenes with remarkable tonal variation.

How should I clean antique glass?

Wash pieces gently in lukewarm water using a mild, non abrasive detergent. Avoid soaking items with metal mounts, enamel decoration, or gilt highlights. Dry thoroughly with a lint free cloth to prevent water spots from forming on delicate frosted or opalescent surfaces.

What is opaline glass?

Opaline glass is an opaque or translucent material developed in France during the nineteenth century. It imitates the appearance of natural opal. These pieces typically feature soft pastel hues and were frequently embellished with hand painted gilt designs or raised floral motifs.
