How do I date an 18th century bowl?

Dating relies on identifying the ceramic body, glaze characteristics, and potting style. Soft-paste porcelain and tin-glazed earthenware point to specific manufacturing periods. Maker marks, where present, help narrow the date further alongside characteristic hand-painted blue and white motifs.

What is the difference between porcelain and earthenware?

Porcelain is vitrified, dense, and often translucent, requiring high kiln temperatures. Soft-paste porcelain and hard-paste varieties both fall into this category. Earthenware is opaque, more porous, and fired at lower temperatures. Tin-glazed earthenware and ironstone represent this heavier group.

How were these bowls used historically?

Punch bowls and tea bowls served beverages during social gatherings in the 18th century. Large vessels held liquids or food at the dining table. Other forms functioned as sugar bowls, jardinières, or decorative dishes displayed in domestic interiors.

Are Dutch Delft bowls different from English pieces?

Dutch Delft utilises tin-glazed earthenware with opaque white surfaces suited to bold cobalt painting. Kraak style influences often appear on these pieces. English factories like Worcester focused predominantly on porcelain bodies, achieving finer painted details on tea wares and punch bowls.
