How do I date an old dish?

Dating relies on examining the potting style, foot rim characteristics, and the specific tone of the cobalt blue pigment. Reign marks can offer guidance, though later pieces frequently replicated earlier marks. Changes in porcelain body density and glaze texture across the Ming and Qing dynasties provide further clues for proper attribution.

Can I use these dishes daily?

Most antique pieces function better as decorative display items rather than for regular dining use. The fragile nature of centuries-old porcelain makes them vulnerable to modern dishwashers and cutlery. Gentle hand washing in lukewarm water preserves the integrity of the glaze and the underglaze cobalt painting.

What causes the different shades of blue?

Shades vary depending on the purity of the cobalt mineral used and the exact temperature inside the kiln during firing. Earlier periods often utilised imported ores that produced deep violet-blue tones. Later production runs achieved brighter, more uniform blue hues as refining techniques for the raw materials advanced.

Why do some pieces have reign marks?

Potters painted reign marks on the base of vessels to honour earlier emperors or to indicate the specific period of manufacture. These marks serve as traditional indicators of workshop standards. Matching the style of the mark to the physical characteristics of the ceramic body helps determine whether the piece is of the period or a later tribute.
