Creating a Double-Walled Raku Cauldron

Mixing the clay AUDIO (:40)

The most important factor for me in making a successful large, double-walled raku cauldron is to have a strong clay body. A clay body capable of withstanding the stress of rapid firing and cooling without cracking. Through trial-and-error, I have developed a very dependable clay formula. The formula is as follows:

  • 10 parts Fire Clay
  • 5 parts Ball Clay
  • 2 parts Grog
  • 1 part Custer Feldspar
  • 1/4 part Spodumene

Before putting the clay on the potter’s wheel, I wedge the clay one hundred times to eliminate any air bubbles.
