The Orton KilnVent |
Question: I am using a clay that produces more fumes than usual. Should I keep the kiln lid open during candling? Should I vent the lid to get rid of the extra fumes? (I am using the Orton KilnVent.) Answer: Some clays contain an especially high number of impurities. If the Orton KilnVent has enough intake vent holes, it can vent the fumes from even those problem clays. a) When using the KilnVent, keep the lid or door completely closed and the peephole plugs inserted throughout the firing. Otherwise the KilnVent will not remove the fumes. This is because the KilnVent requires negative air pressure inside the kiln. Keep the door/lid closed and plugs inserted even during candling. b) If you smell fumes in the room while the KilnVent is running, you may need an additional air intake hole for the KilnVent. Orton has published a chart showing recommended number of intake holes for each size kiln. You can obtain that chart by calling Orton at 800-999-5442. Arnold Howard Paragon Industries, Inc.
