What is cobalt blue delftware?

Cobalt blue delftware consists of tin-glazed earthenware ceramics decorated with blue oxide pigments. These objects include decorative plates, chargers, bowls, jars and tiles. Potters across England and continental Europe produced these items primarily during the seventeenth, eighteenth and nineteenth centuries.

How were chargers used?

Large chargers served mainly as decorative wall hangings or table display pieces rather than everyday tableware. Their wide rims provided an ideal canvas for intricate painted landscapes and floral motifs. Wealthy households used them to showcase fine craftsmanship in principal rooms.

How do I date antique delftware?

Dating relies on analysing the ceramic body, glaze characteristics, painting style and recorded workshop marks. Seventeenth-century pieces often display thicker tin glazes and distinct compositional layouts compared to later items. Specific forms like drug jars and posset pots also carry stylistic clues tied to particular decades.

How do I care for tin-glazed earthenware?

Tin-glazed earthenware requires gentle handling because the ceramic body beneath the soft glaze is porous. Keep pieces away from excessive moisture and sudden temperature changes to protect the glaze surface. Dust them softly with a dry cloth rather than washing them with water.
