      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.

Talc bodies

Recommended Posts

Hi everybody

I make my own bodies for my ceramic works. The formula is very simple such feldspar, local clay, and china clay (high fired body). Actually the formula has already make me satisfied. But I have read that the body formula can be added talc to lower the vitrified body. Also talc can make the body has a good thermal shocking. I just wanna make sure of that statement. How about whiting? what is the used if added to the body. I really appreciate for any reply.

Thank you :rolleyes:src="http://ceramicartsdaily.org/community/public/style_emoticons/default/rolleyes.gif">

I don't know about your materials sources there in Indonesia, but here in the USA a number of the traditional sources of talc for ceramics were found to have significant trremoline asbestos contamination in them in the past few years. So be careful of this potential approach.

 

How far "down" do you want to take the firing cone?

 

best,

Thanks for replying. I must check to the suplier for what you said. I wish it doesn't contain any harm subtances. Because I have been using talc for many years. And from related institutions do not announche the hazards of this material. Are there any substitutes material for talc which have same characteristic (for body)?

My formula body has vitrification point at 1230 celsius. I want to lower until 1200 celsius. Can I add whiting or anything else?

Thank you..
