Can I use these bowls for serving fruit daily?

These bowls serve their original purpose well for holding display fruit or dry arrangements on a sideboard or dining table. Their sturdy moulded construction handles everyday placement without issue. Take care with acidic fruits left for extended periods, as old glass surfaces can be sensitive to prolonged chemical contact. Hand washing immediately after use keeps the interior finish bright.

How do I identify a signed piece?

Look along the outside base edge, the underside, or within the interior relief for acid-etched, sandblasted, or moulded signatures. Signatures often correspond to the specific foundry or designer active during the period. Faint marks require angled lighting and a magnifying glass to read properly without damaging the surrounding surface. Unsigned pieces still appear from reputable makers based on their specific mould patterns.

What is the difference between opalescent and frosted glass?

Opalescent glass contains chemical agents that cause the material to scatter light, producing a milky blue or amber glow across raised surfaces. It shifts appearance depending on the angle of the room illumination. Frosted glass relies on acid-etching or sandblasting to create a uniformly matt texture across the piece. While both finish types soften the transparency, opalescent glass retains an internal fire.
