How do I identify an authentic piece?

Authentic pieces typically feature acid-stamped, wheel-engraved, or enamelled signatures belonging to the maker on the body or base. Examine the depth and crispness of the etching, as period techniques left distinct textural nuances. Familiarise yourself with the characteristic motifs and colour palettes associated with French glasshouses from the Art Nouveau and Art Deco eras. Signatures alone require careful corroboration against known period examples.

What is the difference between Art Nouveau and Art Deco styles?

Art Nouveau examples from the turn of the twentieth century favour organic lines, floral subjects, and flowing naturalistic landscapes. Colours tend to mimic the subtle tones found in nature. Art Deco pieces from later decades embrace modernist geometry, stylised motifs, and bolder, contrasting colour combinations such as orange on purple. The forms become more architectural and streamlined.

How should I display these vessels?

Place your vessel in a location with adequate natural light to illuminate the layered colours and intricate etching. Transparent and translucent cameo glass responds particularly well to backlighting. Ensure the display surface is stable and protected from direct sunlight or heavy foot traffic that could cause accidental knocks. Keep them away from extremes of temperature.
