Lidded Storage Jar: a Coil-Built Pot with a Fitted Flanged Lid
Fired clay does not rust, react with salts or let light through, which is why herbs, pigments and remedies were kept in clay jars. This is our coil pot with a straight neck and a lid that sits inside it on a flange, made from the same clay at the same time so both shrink alike.
The picture: a lidded earthenware jar with a horn handle, Korea, Silla or Kaya period (Cleveland Museum of Art).

Make the lid
While the jar is still soft, roll a disc a little wider than the mouth. Measure the inside of the neck and add a coil ring underneath the disc that just fits inside it: the flange that keeps the lid from sliding. Score, slip and join it, and add a knob on top.

Dry and fire together
Dry them slowly to bone-dry, the lid off the jar, and fire them in the same pit firing as the coil pot, so they shrink alike.
