How do I date a blue and white dish?

Dating relies on identifying the ceramic body, such as pearlware versus soft-paste porcelain, and examining the transfer-printed pattern for historical context. Potters' marks on the underside also help narrow down the manufacturing decade. Style clues like border designs and topographical subjects further anchor pieces to the eighteenth or nineteenth century.

Are these dishes safe for daily use?

While these antique ceramics served practical dining purposes originally, modern use risks thermal shock and surface wear. Historic glazes can also contain trace elements. Collectors generally prefer to display or use them gently for dry foods rather than everyday dining.

Why is the blue colour blurry on some pieces?

Blurring happens when the cobalt ink bleeds slightly into the glaze during the high-temperature firing process. Early transfer-printing techniques sometimes struggled to keep lines pin-sharp. This minor diffusion is characteristic of period manufacturing rather than a modern flaw.
