How do I date blue and white porcelain?

Dating relies on factory backstamps, glaze characteristics, and stylistic conventions associated with periods like the Victorian era or the eighteenth century. Form and potting weight also provide clues, as earlier pieces often show different clay bodies compared to later ironstone or transferware.

Are converted lamps safe to use?

Many antique vases and jars have been fitted for electricity to serve as table lamps. Rewiring by a professional ensures modern electrical safety while preserving the ceramic vessel. Drilled bases or fitted mounts are common modifications found in historical lighting conversions.

How should I clean antique porcelain?

Gentle washing in warm water with mild soap preserves the glaze and any delicate enamel or gold leaf overglaze details. Abrasive sponges or harsh chemicals must be avoided to protect the surface. Pieces with metal mounts or porous earthenware bodies require careful spot cleaning rather than total immersion.

What is the difference between porcelain and earthenware?

Porcelain is fired at higher temperatures, resulting in a vitrified, non-porous body that often rings when struck and appears translucent under strong light. Earthenware and ironstone are more opaque and absorbent. Delft and certain utilitarian wares are typically earthenware with tin glazes rather than true hard-paste porcelain.
