Most of my pottery is currently made of high fire (2350º F) porcelain or stoneware clay. It is non-toxic and quite durable. It may be placed in the dishwasher, microwave or oven. Since it has been fired to 2350º F, even 500º in your oven will not affect it.
However, please do not take it from one extreme temperature to another (like from the fridge directly into hot water. Properly cared for, your pottery should last at least as long as low-fire pottery has from Ancient Egypt or Greece....
say, 3 to 5000 years!
Do not use metal scrubbers on the surface as eventually it will scar the glass-like surface. Do not drop or toss onto hard surfaces like the floor. Do not leave it behind at your family’s potluck picnic.
If you do break it, you can glue it back together and use it some more or make into a beautiful mosaic.
My sgraffito ware is made of grolleg porcelain painted over with a pigmented porcelain slip. I draw freehand on the surface and then carve away whatever is not part of my image with small wire loop tools.
I draw inspiration from varied sources. The cave paintings of France and Spain are a wonder to me as are the fine pots of the Mimbres of Southwest United States. I am also an admirer of Kenojuak Ashevak of Cape Dorset.
Many ancient pottery industries inspire me; ancient Egypt and Greece, Pre-Columbian Panama and Equador.
I have been influenced first by my first teacher in 1969, Norboro Kubu and then in 1976, Bob Broderson and then certainly in college, Warren Mackenzie. Later at Lill Street in Chicago I must mention Kelley Kessler, Lisa Harris and Xiaouxang Bi.
Potters I’ve admired must begin with Matt Metz.
