I have added a gold and silver lustre to my desk pets for a little pizazz. It is kinda a cool process because it is actually real gold (and white gold) and it requires a third firing to melt the gold into the glaze.
These little demon monsters are perfect for sitting on your desk to keep you company. But they are damned cute! And so flipping happy!
They grow free in the wilds of the California coast, frolicking through wildflowers and sea lion carcasses. 
This one is of the smooth stoneware breed. From sturdy, high-fire B-mix clay. Dense, Rugged and Vigorous.

This one measures about 4" tall by about 3.25" in diameter.
