      Moderators needed!   12/08/2017

      Ceramic Arts Network is looking for two new forum moderators for the Clay and Glaze Chemistry and Equipment Use and Repair sections of the Ceramic Arts Network Community Forum. We are looking for somebody who is an active participant (i.e. somebody who participates on a daily basis, or near daily) on the forum. Moderators must be willing to monitor the forum on a daily basis to remove spam, make sure members are adhering to the Forum Terms of Use, and make sure posts are in the appropriate categories. In addition to moderating their primary sections, Moderators must work as a team with other moderators to monitor the areas of the forum that do not have dedicated moderators (Educational Approaches and Resources, Aesthetic Approaches and Philosophy, etc.). Moderators must have a solid understanding of the area of the forum they are going to moderate (i.e. the Clay and Glaze Chemistry moderator must be somebody who mixes, tests, and has a decent understanding of materials). Moderators must be diplomatic communicators, be receptive to others’ ideas, and be able to see things from multiple perspectives. This is a volunteer position that comes with an honorary annual ICAN Gold membership. If you are interested, please send an email outlining your experience and qualifications to jharnetty@ceramics.org.

Best Cone 6 Porcelain?

Recommended Posts

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.

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.

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.

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.

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.

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.
