Panamax Posted July 15, 2010 Report Share Posted July 15, 2010 I have recently been told to apply kiln wash to the bottom of a 6 month old skutt kiln. I had always heard not to do this. What is the best procedure, kiln wash bottom of kiln or not? Thanks!! Link to comment Share on other sites More sharing options...
Marcia Selsor Posted July 15, 2010 Report Share Posted July 15, 2010 I say wash it. I had a crystalline glaze eat a three inch hole in a brand new kiln when I first started with crystalline glazes back in 1972. Soda is very corrosive to soft brick. Many glazes are corrosive to soft brick. That is why is is a good practice to wash the kiln floor. I always coated kiln wash on the kiln floor of the gas kilns too. It made it easier to keep them crud free. Work that blows up with a glaze on it can be tough to clean without chipping bricks. I also coated the walls and lids or arches with ITC. It insulates as well as protects. Link to comment Share on other sites More sharing options...
Colonel Potter Posted July 22, 2010 Report Share Posted July 22, 2010 I coated the whole thing with ITC and should have coated the bottom also with kiln wash. Now I have a big divit in the ITC coating. I also had a cone fly off of the cone boat and make a mess. With kiln wash I could have cleaned it up.

bciskepottery Posted July 23, 2010 Report Share Posted July 23, 2010 When I got my kiln, I did not apply kiln wash to the bottom brick. However, I did place a shelf (that was kiln washed) on 1/2 inch posts on the bottom. My kiln is vented through the bottom and a shelf with slight elevation allows for air circulation/venting during firings. Link to comment Share on other sites More sharing options...
