claclana Posted October 12, 2014 Report Share Posted October 12, 2014 Hi, I was doing 12'x12", 1//4" thick tiles (hearth clay, with and without grog, cone 04-06 using slab roller, electric kiln ) and firing each resting on each kiln shelf with good results , but the quantity to be fired is pretty limited. I try different tile setters but cracks and warping happened, even those tiles that were pre fired (or the second firing weakens them further!?) I thought I could do porcelain(?) tiles 13x13, 1/2" thick to use as "shelves" so I can put more all- surface-supported tiles in the kiln. I also thought pre fired the "shelves"before putting them to work, metal would be the best but I know will melt... do you have some suggestions for alternative kiln shelves? I apologize for my massive ignorance Thanks Link to comment Share on other sites More sharing options...
Min Posted October 12, 2014 Report Share Posted October 12, 2014 I don't think porcelain is going to work as tile setters. It's going to warp, sag and probably crack. Plate or tile setters, or cranks, are made of the same materials as kiln shelves and don't warp, sag etc. If you can't find any big enough for your 12" tiles and the cost is justified I would buy some kiln shelves and use those as in the tile setter picture here. Tile setters that just support the corners are for low fire glaze firing after the tiles have been vitrified or for tiles that don't come to the clays top temp so they don't sag.

art81usa Posted October 13, 2014 Report Share Posted October 13, 2014 I knew someone who uses sand for her tiles to rest on to help with cracking and stuff. Not sure if this will help you or not. I believe she puts enough so it can rest easily on the sand. Hope this helps. Link to comment Share on other sites More sharing options...
Marcia Selsor Posted October 13, 2014 Report Share Posted October 13, 2014 you could make the corner style supports using a kiln furniture recipe. This one is from Linda Blossom. Good to ^6 or higher possibly. She uses cone 6. Kiln Furniture Clay Ball Clay 10% Fire Clay 50% Ground Brick 50% OR Laguna #2272 fire to ^10 Link to comment Share on other sites More sharing options...
