clay lover Posted January 6, 2017 Report Share Posted January 6, 2017 When my shipment arrived, the talc is gray not the pure white I have used before from the same supplier! What is gray talc ? Link to comment Share on other sites More sharing options...
Joseph Fireborn Posted January 6, 2017 Report Share Posted January 6, 2017 I have had all different colors of talc. Grey is what mine currently is. Just test it before mixing a large batch of glaze. Link to comment Share on other sites More sharing options...
Sheryl Leigh Posted January 6, 2017 Report Share Posted January 6, 2017 Mine is gray, as well. Link to comment Share on other sites More sharing options...
bciskepottery Posted January 6, 2017 Report Share Posted January 6, 2017 Talc is coming from a differing source . . . the old white was discontinued due to asbestos concerns. The gray -- which I believe comes from a Texas source -- fires to white. http://www.highwaterclays.com/files/%20Talc%20in%20the%20News.pdf Link to comment Share on other sites More sharing options...
Dick White Posted January 6, 2017 Report Share Posted January 6, 2017 The grey color in the currently available Texas talc is from extraneous carbon. It will burn out. Link to comment Share on other sites More sharing options...
Mark C. Posted January 6, 2017 Report Share Posted January 6, 2017 Its Texas talc also known as Pioneer Talc-its grey in color-been that way for years Some talcs are white and do not have asbestos. Some of the older white ones like New York Talc had asbestos These all are now hard to find. I know more than I will say but thats the short story. please mail me your older white talcs as you may not want them in your studio anymore-I'll pay the shipping costs of white talcs.

curt Posted January 6, 2017 Report Share Posted January 6, 2017 The talc is plenty white down here in Australia. I think it is because the sun is stronger here. Or maybe the coriolis effect. Not sure which. Link to comment Share on other sites More sharing options...
clay lover Posted January 6, 2017 Author Report Share Posted January 6, 2017 Bcisk, both came from Highwater The white about 3 years ago. I'm wondering what changes it will make to my glazes . Mark, you obvioudly find the white more desirable , and I appreciate your offer to help. Link to comment Share on other sites More sharing options...
glazenerd Posted January 6, 2017 Report Share Posted January 6, 2017 Bruce said The gray -- which I believe comes from a Texas source -- fires to white. The color of the talc is a non-issue; at bisq temp it will be white. Grey are just carbons, that readily burn off. Nerd Link to comment Share on other sites More sharing options...

Marcia Selsor Posted January 6, 2017 Report Share Posted January 6, 2017 I have not seen any difference in the different colored talcs, either. Marcia Link to comment Share on other sites More sharing options...
Mark C. Posted January 6, 2017 Report Share Posted January 6, 2017 The only reason I have for the old talcs is I have a buttery satin matte that demands the old stuff. I have a limited supply of it. I use Serria white in all other uses and the grey stuff in one glaze. Serria white is a white talc still available from Laguna Clay Co. The grey talc will work just fine in 99.9 of uses Serria white does not work for my satin matte. Only the old talcs from the 60-70-80's work-talks like Desert Talc from California (long gone or C-30 talc from the 80's. Back in the old days there where no choices on this now there are several choices but you have to look for them.I like serria white for most of my talc uses. I stopped using Texas talc when I sold my longhorns Link to comment Share on other sites More sharing options...
Marko Posted January 8, 2017 Report Share Posted January 8, 2017 Texas Talc is grey. I also use it. It won't change the glaze color. I haven't had any problem with it. Link to comment Share on other sites More sharing options...
bethkam Posted November 8, 2018 Report Share Posted November 8, 2018 If you want white talc, you must order French Talc. Haven't done any glaze tests yet to determine if there's a difference in glazes between the gray and French talc. Link to comment Share on other sites More sharing options...
Mark C. Posted November 12, 2018 Report Share Posted November 12, 2018 French talk is for cosmetics at 8$ at pound you can see why cosmetics cost so much. No ceramic supplier I know on the west coast carries French talc You can buy it on the web-no telling what its make up is or where its from?
