How do I clean an iridescent glass surface?

Dust the surface gently with a soft, dry cloth to prevent accumulation. Avoid abrasive cleaners or soaking, as chemical treatments can damage the delicate metallic sheen. Maintain stable indoor humidity away from direct sunlight to preserve the optical layer. Handle pieces by the body rather than delicate rims or applied metal mounts.

What period do most iridescent vases belong to?

The majority of pieces date from the early twentieth century and the late Victorian era. This period encompassed the rise of Art Nouveau and Secessionist design across Europe and England. Production continued into the nineteen twenties with Art Deco lustre wares. Stylistic markers and maker signatures help narrow the date of manufacture.

How can I tell glass from lustre pottery?

Glass vessels are translucent or transparent beneath their metallic skin, often showing blown bubbles or pontil marks on the base. Earthenware and pottery bodies are opaque ceramics covered in a reflective glaze. Weight and rigidity also offer clues, as pottery feels denser and heavier than blown art glass. Examining the unglazed base reveals the underlying clay body.

Were these vases meant for flowers?

Many forms, particularly floriform and baluster shapes, served as functional vessels for cut stems. Others functioned purely as decorative ornaments or table centrepieces. Displaying them in natural light enhances the optical play of the iridescent surface. Some fragile examples with silver overlay or delicate mounts are best kept as cabinet pieces.
