kraythe Posted November 7, 2017 Report Share Posted November 7, 2017 I finished my test run from my kiln and literally every clear glaze came out crazed, despite having some supposedly anti-craze glazes. I don't know what to use for this clay body I am using and I have about had it up to the neck with trying to find something to fit it. So I am looking for recommendations on good clay bodies for cone 6 porcelain that will actually fit some glazes. I am even open to going to cone 10 porcelain. I have limited time to do pottery and want something that I can actually fire to be functional pieces. I am open to suggestions. Thanks. Link to comment Share on other sites More sharing options...
neilestrick Posted November 7, 2017 Report Share Posted November 7, 2017 I have great results with Standard #365. Throws great, glazes fit, etc. Link to comment Share on other sites More sharing options...
Chris Campbell Posted November 7, 2017 Report Share Posted November 7, 2017 There is no such thing as “anti craze”glazes. Sorry, but just as there are no jeans designed to fit all sizes, glazes need to fit the clay they are put on. Put size 2 jeans on a size 10 person and something has to give. Tell people which clay you are using and they might be able to recommend a glaze. Link to comment Share on other sites More sharing options...
kraythe Posted November 8, 2017 Author Report Share Posted November 8, 2017 I am using a cone 5-6 porcelain from my local supplier and I have had crap luck getting anything to fit without crazing from 5.9 COE glaze though 7.1. It's all a matter of degree how bad. My wife said the pots were crackling long after being unloaded even though I waited until I the kiln parts could be unloaded by hand to unload. I am using an olympic 1827g gas kiln. Link to comment Share on other sites More sharing options...
LeeU Posted November 8, 2017 Report Share Posted November 8, 2017 It would probably help to know the name/manufacturer of the type of porcelain you are using, or getting the recipe/components of the body from the maker. Link to comment Share on other sites More sharing options...

I wish I knew. They wont tell me crap about this clay, not whats in it, nothing. They just say its COE is 6.0 to which I call Bullsh...op. They wont event tell me what the recipie they have for it to not craze has in it so I cant use that as a base glaze. Basically I am sick of this clay and interested to moving to something else. I am used to working with midfire porcelain but not opposed to going to stoneware if I can find one with a nice texture or even high fire porcelain.

Joseph Fireborn Posted November 8, 2017 Report Share Posted November 8, 2017 You need to provide us with more information. What cone are you firing to? What type of kiln? Where are you located? What suppliers are near you besides the one you are currently using? I find the best basic cone 6 porcelain is what Neil recommended. Standard 365. It fires a nice white, glazes fit well, it throws good and fires consistent. There are other nice porcelains but they are not as forgiving as standard.

Cindy S. Hess Posted December 31, 2017 Report Share Posted December 31, 2017 I just started using Standard 365 and am having a problem finding a clear glaze that does not craze. Can you tell me what clear glaze you use with 365? I fire to cone 6. Link to comment Share on other sites More sharing options...
Marcia Selsor Posted December 31, 2017 Report Share Posted December 31, 2017 I am on the other side of the country and don't want to ship from Pittsburgh. My favorite ^6 porcelain is Frost. Next is Bray ^6 porcelain. I am mixing my own glazes. One good standby clear for me is Hinze Clear I have posted the recipe before. Will look for it again.

Roberta12 Posted December 31, 2017 Report Share Posted December 31, 2017 If you are mixing a clear glaze, there are a few to try. I don't have access to Standard, but have tried all of Laguna and Aardvark and Continental's midfire porcelains. Get your hands on a copy of Mastering Cone 6. They have a couple of clears in there. Min gave me a clear recipe, I mixed up a small batch and now that Christmas is over will do further testing on it. I also mixed up a small batch of Low Expansion Clear out of the John Britt book. More testing on this one as well.
