Choice of clay

This method of coil-and-throw can be successful with a diverse range of clays. The clays best suited are those that are moderately plastic with a large particle size and an open structure. Those that allow the moisture in the wall to move relatively freely from the inside to the surface where it is driven off.

Clays that have a high proportion of very fine particles require more care when accelerating the drying. Black Wattle White Grogged Paper Clay is an example of that is well suited for coil-and-throw and high firing.

To assist in keeping the band of new clay under control, the clay for coil-and-throw should be slightly firmer than for normal throwing.

It should be remembered that large pots also need to be handled around the studio, glazed and fired. Dry strength and firing properties should also be considered when choosing a clay.
