up north potter Posted January 2, 2011 Report Share Posted January 2, 2011 I would like to build a cross draft soda kiln. I want to make it out of fiber for ease of construction. So I want to know if someone has a solution/coating to prevent the atmosphere from melting the fiber. I've built several kilns, and understand general construction techniques and just want advice. Is this a bad idea?? thanks, Robin Link to comment Share on other sites More sharing options...
bciskepottery Posted January 3, 2011 Report Share Posted January 3, 2011 Hank Murrow has built some beautiful fiber kilns -- he fires gas to cone 10. His website is at http://www.murrow.biz/hank/ Nils Lou discusses his experience with various refractory coatings in his book "The Art of Firing".

Deb Evans Posted January 3, 2011 Report Share Posted January 3, 2011 As far as I know, soda will degrade fiber. Have used it successfully on the outside of soda kiln for more insulation. Link to comment Share on other sites More sharing options...

Is this a bad idea?? thanks, Robin I don't think this is a good idea Robin. In the 90's I decided to do a couple of soda firings in my ancient, Geil, fiber kiln. It sprayed the interior with ITC 100 and after just a couple of firings the old fiber just wouldn't stay put with the ITC. If you're looking for light construction you might try using IFB's, and coating 5 sides of interior bricks with the ITC 100. My next kiln was an all hard brick kiln except for the door which is IFB's. A hard kiln will last much longer than an IFB kiln, even with ITC. I guess it depends on your budget, possible portability, location, etc; but you can't go wrong with the hard bricks for longevity.

Is this a bad idea?? thanks, Robin I read a paper written by a British potter who spent a lot of time trying to build an insulating kiln with the ability to withstand the harsh environment of sodium. http://kilnshelf.publishpath.com/Websites/kilnshelf/Images/Insulating%20Materials%20for%20Salt%20Kilns%20Article.pdf Link to comment Share on other sites More sharing options...
neilestrick Posted October 11, 2011 Report Share Posted October 11, 2011 Having built a few soda kilns, my preferred method is to use hard brick for the interior for durability, soft brick for the exterior for insulation. Anywhere the floor supports shelving must also be hard brick all the way through, as well as all burner ports and salting ports. No coating is necessary on the interior. Just let it glaze over. I also prefer power burners over venturi burners as they disperse the vapor much better. Link to comment Share on other sites More sharing options...
