Pots in exposed parts of the kiln show the effects of fly ash landing on unglazed surfaces (known as flashing); for this reason, many of them are left unglazed or part-glazed.

The glazes used on the pots are usually simple mixtures of locally dug clay, vegetable ash and feldspar.

Although unsophisticated, these glazes can be very beautiful, sometimes producing unexpected bonuses such as the blue "chun" glazes seen on some of the pots.
