Alyosha Posted March 27, 2022 Report Share Posted March 27, 2022 Hello, I am venturing in glazing stoneware with rocks, clays and ashes. However I mainly throw a local marl hectorite earthenware clay that I have fired up to 1150⁰C probably close to it's melting limit, with results at 1020⁰C of the green clay becoming orange red. Is there any approach to using natural- un industrial mined ingredients in this range ? Link to comment Share on other sites More sharing options...
Babs Posted March 27, 2022 Report Share Posted March 27, 2022 Lots bwen written on thIs tile with bitas of the materials on it to see how It melts without fluxes. Then I guesa ball milling and crushing. Think some crush better after a bisque. Link to comment Share on other sites More sharing options...
Alyosha Posted March 27, 2022 Author Report Share Posted March 27, 2022 Thank you Babs, I haven't found any written material about low temp natural glazing Link to comment Share on other sites More sharing options...
Babs Posted March 28, 2022 Report Share Posted March 28, 2022 Not sure where you are bht Libraries. Search glazes from natural sources. Unmined, like on side of road?? On the top? Link to comment Share on other sites More sharing options...
Babs Posted March 28, 2022 Report Share Posted March 28, 2022 The above book states for all temps. Then there are terra sigellatas. Link to comment Share on other sites More sharing options...
Alyosha Posted March 28, 2022 Author Report Share Posted March 28, 2022 Hello Babs, Thanks. I missed this book although then author name sounds familiar. I live in the parisian suburb. Yes , some from the side of the road, from trees or from building construction sites, Link to comment Share on other sites More sharing options...
Alyosha Posted March 28, 2022 Author Report Share Posted March 28, 2022 Like other ceramic books that seem very interesting, the book is out of print and therefore prohibitively expensive. I guess I'll do tests from scratch Link to comment Share on other sites More sharing options...

I guess I'll do tests from scratch Hi Alyosha, The book is indeed out of print (both the first and second edition) and it really is a bummer. That's why I did a PDF copy (of the first edition) in a library in Canada. I am always willing to retribute authors for their work but when it's not available, well it's not available... and those kind of very specific topics are not likely to be reprinted soon, sadly. I sent you a private message (also with questions about a pyrometer that you created a topic about). Feel free to answer me. Link to comment Share on other sites More sharing options...
