Ginny C Posted March 11, 2015 Report Share Posted March 11, 2015 This topic has been discussed many times, but I haven't seen a clear explanation of how to use glaze to do this. A hand-built piece with a small thrown pedestal/foot supporting the center of the dish came apart. (I know I failed to used enough slip originally! ) Would it work to mix some Elmer's glue with some glaze (I don't have any dry glaze material) and glaze fire it? I would glaze both pieces separately and then use the mixture to attach them and set them right on the kiln shelf to dry before firing. The weight of the dish should keep it in place on the circular foot, I would think. Will the glaze adhere the two parts? I'd like to get away without having to re-bisque it!

Marcia Selsor Posted March 11, 2015 Report Share Posted March 11, 2015 Best to reattach with paper clay and re bisque. It is made of toilet paper soaked overnight and mixed in a blender,add your clay dried and pulverized, vinegar, a dash of sodium silicate and a little Karl syrup. make it a thick consistency. before applying to the bisque , soak the surface with water so that the bisque won' t suck all the moisture too quickly out of the paste. Apply to both surfaces and stick together holding until it holds on by itself. re bisque. then you can glaze. very important to re bisque before applying glaze. marcia Link to comment Share on other sites More sharing options...
Mark C. Posted March 11, 2015 Report Share Posted March 11, 2015 Marcia's method works great but if you do not want to wait for rebisquing several products work well for this. Bisque fix is one from amaco works great for this- another is high fire mender by Aztec (this mixes with your clay body so it matchs well) another is Lees patch which Axner bought out and now has thier own product also works but is a bit whiter. I have used all of them with great results.You apply reattach let dry glaze and fire.These all cost money but do not need to be bisque fired first. All can be had from retailers or mail order/net sales-kiln cement also works in a pinch. Mark Link to comment Share on other sites More sharing options...
rakukuku Posted March 11, 2015 Report Share Posted March 11, 2015 While I have done the elmer's glue and glaze thing for small sculptural things, I would be afraid that having just glaze hold your piece together would not be strong and lead to the foot coming off at some point. I would sand the bottom of the dish to make it sit flat and discard the foot. rakuku Link to comment Share on other sites More sharing options...
John Hertzfeld Posted March 13, 2015 Report Share Posted March 13, 2015 The glue will burn out well before the glaze melts - possibly displacing the glaze a little as it boils away, if you glaze each part and set together, in your intended arrangement, the glaze will melt and fuse the two pieces as the glazes become part of each other. If you've ever seen a piece fused with a shelf you know that this should be ok for daily use. Link to comment Share on other sites More sharing options...

If you've ever seen a piece fused with a shelf you know that this should be ok for daily use. Ahh. So you mean I can skip the glue and just use the glaze on both parts, set them down carefully in the kiln so the dish is centered on the foot ring and fire away? That sounds good to me. I'll try that. And I'll post results, probably next week. I was about to mix up the paper clay stuff and I was considering adding everything to the mix: slip, APT-II, sodium silicate, the TP nicely broken down into a slurry, and maybe bentonite and sugar! I've seen all those in various formulas, but never all together. Next time I need a really good bisque repair done I might try that. What do you experts think? (I know I'd need to then re-bisque fire it.) Link to comment Share on other sites More sharing options...
John Hertzfeld Posted March 14, 2015 Report Share Posted March 14, 2015 I believe the other fix it ideas are intended for harder to glaze fuse items like handles and such, here you have stability, Gravity, and glaze working with you. A handle would be hard to affix this way, even if it was horizontal like a pot lid strap handle, just too wobbly Link to comment Share on other sites More sharing options...
oldlady Posted March 14, 2015 Report Share Posted March 14, 2015 you might want to try to fire the piece on the top shelf. i did the same thing years ago and put the bowl shape onto the foot at an angle. since it was down inside the kiln i couldn't see it until it was fired into a lovely tilted compote. on the top shelf you can prop a mirror at the edge and see the join better. tilted compotes can be made into attractive fountains if you have a collection of them.

Roberta12 Posted March 14, 2015 Report Share Posted March 14, 2015 This forum helped me with a similar problem. I had the paper clay on hand so I used that, rebisqued, and TA DA! It worked. But.....I think I will get some of that patch stuff, so you wouldn't have to rebisque. but the paper clay works! Link to comment Share on other sites More sharing options...
Ginny C Posted March 17, 2015 Author Report Share Posted March 17, 2015 Glaze is a great glue!! Here's the result of just putting lots of glaze on both parts and setting it carefully on the top shelf. Link to comment Share on other sites More sharing options...
Benzine Posted March 17, 2015 Report Share Posted March 17, 2015 Yep, I often use glaze to adhere pieces. Usually they are broken, because students weren't careful. It works fairly well, especially with pieces that are held together with gravity, like your's. The only downside to using glaze, is that if it gets tapped a few times, it can break apart. Basically the same principle as how you get pieces apart, that had some glaze get between them. Just tap them a bit, and the glaze essentially cracks/ shatters. So this could happen with your piece. I've seen antique, large ceramic wares, that had the top portion attached with glaze. Over the years, the glaze crack, and the pieces came apart.

John Hertzfeld Posted March 17, 2015 Report Share Posted March 17, 2015 Glad it worked out, be sure to score deeper next time and they should stay together in the bisq. Link to comment Share on other sites More sharing options...
