How do I identify an art nouveau decorative bowl?

Look for asymmetrical, flowing lines, botanical motifs, and stylised representations of insects or figures. Lustre glazes and iridescent glass finishes are also strong indicators of the period. Examine the base for maker marks, pattern numbers, or signatures that link the piece to known potteries and glasshouses of the early twentieth century.

Where were these bowls placed originally?

These vessels functioned primarily as table centrepieces, side table ornaments, or serving dishes in Edwardian and early twentieth-century homes. Larger bowls and epergnes held fruit or floral displays during formal meals. Smaller lustre and porcelain bowls served as decorative accents on mantelpieces, display cabinets, and entrance hall furniture.

What is the difference between lustre glaze and standard pottery?

Lustre glaze incorporates metallic salts fired in a reduced oxygen environment to produce an optical interference sheen. This creates a reflective, rainbow-like surface distinct from standard opaque or clear ceramic glazes. Standard pottery relies on coloured mineral oxides for flat or uniform hues, whereas lustre surfaces shift in colour depending on the angle of ambient light.
