The following murals are made of a clay body I constructed which is capable of absorbing extreme shrinkage stresses and is formulated to work with our alkaline glazes. This allowed for the construction of one-piece, i.e. seamless, one inch thick slabs of up to 36 inches by 24 inches, the maximum size my kiln allowed, and a high relief of about 12 inches. I started to treat these murals as a canvas for oil paint and other mediums post firing, instead of glazing them. These murals are labelled 'Once-fired'. The other murals, with the exception of Old Man Tree, are also made of my high tensile clay, but are glazed in a traditional manner.
