What is a moulded glass dish?

A moulded glass dish is a table or display vessel formed by pressing hot glass into a shaped matrix. These items range from eighteenth-century English sweetmeat stands to twentieth-century French opalescent bowls. They encompass plates, chargers, and footed vessels designed to hold food or stand alone as decorative objects. The moulding process transfers relief patterns directly onto the glass body.

How do I care for antique glass?

Antique glass requires careful handling and gentle hand washing in lukewarm water with mild detergent. Avoid sudden temperature changes to prevent thermal shock and cracking in older material. Store pieces on stable, flat surfaces away from direct sunlight and heavy vibrations. Use padded shelving where appropriate to protect delicate rims and moulded feet.

How do I date a glass dish?

Dating relies on stylistic markers, manufacturing techniques, and material composition characteristic of specific eras. Eighteenth-century pieces often show pontil marks and heavy lead content, while 1930s works display Art Deco motifs and maker signatures. Examining the depth of the mould work and the presence of specific surface treatments helps place an object within periods such as the Georgian era or the interwar years.

What is opalescent glass?

Opalescent glass is a specialised type of glass that exhibits a milky, glowing quality when illuminated. The material scatters light to produce characteristic blue tones in daylight and amber hues against direct light. This effect was achieved through specific chemical additives and cooling methods. It became a defining feature for decorative bowls and plates during the early twentieth century.
