An Outdoor Raku Firing at Kiser Art Studio in West Liberty, Iowa in April, 2007.
That was the short version. Here are a few more details.
The Raku Kiln gets fired up using weed burners inserted into the sides at the bottom. The pottery (also called Raku) has been glazed (with Raku glazes) and bisqued (fired to harden it and ready it to accept glazes).
The kiln is loaded with clay and the burners are lit. Nothing to do now but wait for it to reach temperature.
After waiting for a sufficient length of time, Marty checks to see that top layer is getting some heat.
“We think we should check the Kiln, too, because it might be hotter by now.”
After what seems like a very long time (20-30 minutes) the pottery is red-hot.
Marty removes each piece with a long pair of tongs. He’s also wearing welders’ gloves to protect his hands from the heat.
