How do I identify underglaze blue decoration?

Underglaze blue decoration feels completely smooth beneath the transparent top glaze because the pigment sits underneath the glassy surface rather than on top of it. Running a finger across the decorated area reveals no raised enamel or texture. By contrast, overglaze enamels applied after the main firing retain a perceptible physical ridge and can sometimes show rubbing or wear from age and handling.

What is the difference between porcelain and earthenware?

Porcelain is a vitrified, non-porous ceramic fired at extremely high temperatures using specific white clays like kaolin, making it resonant and translucent when held to light. Earthenware utilises coarser clays fired at lower temperatures, producing an opaque and heavier body. English transferware and early pearlware pieces on this page are typically earthenware, whereas the Chinese and Japanese items are predominantly porcelain.

How can I date an antique blue and white plate?

Dating relies on examining the potting characteristics, foot rim construction, glaze pooling tendencies, and any reign marks or maker stamps present on the base. Stylistic clues within the transfer-printed borders or painted motifs also provide reliable chronological markers for English and Asian wares. Comparing the potting weight and glaze coloration against documented examples from the same production period helps narrow down the decade of manufacture.

Were these vessels meant for daily use?

Many of the plates, platters, and bowls served active domestic dining roles in period households, while specialised forms like brush washers and scholar's objects fulfilled scholarly pursuits. Large chargers and decorative vases were primarily intended for visual display in reception rooms and parlours. Over time, functional items transitioned into collector cabinets as their historical and aesthetic value surpassed their original utility.
