mrcasey Posted January 4, 2015 Report Share Posted January 4, 2015 Is there any kind of glaze I could put together that might melt and form glass at, say, 1500 F? I don't care about functionality, stability, or anything like that; I just want something interesting to happen. The fluxes I have on hand are wood ash, whiting, wollastonite, frit 3134, and frit 3195. I've also got an assortment of ball clay, kaolin, silica, and coloring oxides. I can also get to a pharmacy or garden center to pick up materials like quick lime, baking soda, etc. Some of the earthenware pots will be green ware, some will have been bisqued to 05, some will have glaze (hopefully), and some wont.

Colby Charpentier Posted January 4, 2015 Report Share Posted January 4, 2015 You can slump common bottle glass at that temp... frit it up and find a way to apply it? edit: A lot of common low fire glazes will be looking for temps closer to ~1900, you could try a bit of frit with just enough clay to bind it. If that won't melt, try a CMC gum or something similar to apply the frit... Link to comment Share on other sites More sharing options...
alabama Posted January 4, 2015 Report Share Posted January 4, 2015 Seems like I remember a Ceramic Monthly article from the 1990s about a girl in Hawaii who developed a low fire raku glaze. She fired the vessels in her backyard BBQ pit. That's all I can remember.. but I think she had a base glaze and changed it by adding different oxides. Good luck Alabama Link to comment Share on other sites More sharing options...
Bob Coyle Posted January 5, 2015 Report Share Posted January 5, 2015 I don't care about functionality, stability, or anything like that; I just want something interesting to happen. Well... Try some frit 3134 and sodium silicate ... maybe 50/50.. who knows... just a guess. Throw in a half a percent ( 0.5%) cobalt carb. Paint it on with a brush till thick, either on leather hard clay or bone dry. Paint the shelf it is to be on with large amounts of kiln wash ( it might run) . put the piece on a ceramic tripod. Fire.... You will probably get someting interesting. Whatever you do, let us know what happened, post the results and pictures. What you are doing is ceramics at it's best. Long live blue sky experimentation! DAMN THE COE... FULL STEAM AHEAD! Link to comment Share on other sites More sharing options...
Tyler Miller Posted January 5, 2015 Report Share Posted January 5, 2015 75/25 Borax to wollastonite? Maybe with a little clay ( ≤5%) just to keep things nice? Link to comment Share on other sites More sharing options...
mrcasey Posted January 22, 2015 Author Report Share Posted January 22, 2015 The yunomi and the chawan are red earthenware (bodies thrown with rough cut feet). Forgot my glaze materials a few counties over and just decided to paint on a slurry of pine ash and miracle gro fertilizer. I also hung tiny pieces of copper wire from the rims. I stuck the cups and some bowls in the center of a bonfire about 5' in diameter. The perimeter of the fire was closed in by sections of large pine trunk. Got a helluva fire going. I stuck in a piece of bisque stone ware and could see it glowing orange. I put in the yunomi, chawan, gp bowl, and large spherical vase. Everything except the vase seems to have vitrified.
