How were these jars used?

These lidded vessels served practical roles in domestic and mercantile settings for storing precious dry goods such as tea, tobacco, ginger, and spices. Their tight-fitting covers protected the contents from moisture and air. Over time, many of these utilitarian containers transitioned into purely decorative objects placed on mantelpieces, sideboards, and displays across European and Asian interiors.

Are the lids usually original?

Checking whether a lid is original to its vessel requires examining the glaze consistency, wear patterns, and clay body match under magnification. Replacements often occurred due to accidental breakage over centuries of handling. While matching period lids remain desirable, many genuine antique pieces survived with married covers fashioned during subsequent generations of use.

How do I date a blue and white jar?

Dating relies on analysing the potting technique, the specific shade of cobalt, base markings, and stylistic clues from the painted motifs. Early pieces often exhibit heavier potting and distinct iron-foot rims. Comparative study against documented factory marks and regional export patterns helps narrow down the century of manufacture.

What is the difference between Delft and porcelain?

Delft utilises a tin-glazed earthenware body that is softer, more porous, and opaque white, European in origin and style. Porcelain is a hard-paste or soft-paste ceramic fired at much higher temperatures until vitreous and translucent. While both display blue painted decoration, the weight, sound, and edge translucency easily separate earthenware from true porcelain.
