Well, I couldn't help it. I and the kids built a small kiln from salvaged brick with a clay and sand mortar. This way they should clean up easy when the test is done and I am happy with the results. I have read that the shells need to reach 900 degrees for a few hours. I am guessing this is with gas as a fuel. I am using wood and it takes a few days as the temp is a bit lower and there are some other benefits with wood. I went out to feed the kiln this evening and was happy to see the shells a cherry red which means they are releasing carbon dioxide and on their way to quicklime.
Happy summer everyone. Tim
