Dmne: matt macro crystalline glazes
----------------------------Original message----------------------------
We're presently experimenting with macro crystalline glazes and have had
some success with gloss glazes. Now we'd like to know if anyone has
experience of matt macro crystalline glazes as we have seen a number of
examples, but can find no literature on the subject. Any help out
there? Thanks, Denise and Viv

Try this:
Red lead 34.9
Silica 25.7
Kaolin 15.8
Rutile 10.1
ZnO 7.4
Whiting 6.1
Fire just under c/7 and hold for 30 min. Take temp down (fast) to c/5 and
hold for 1-3 hour.
Or this:

Fire to c/9, drop to c/7 and hold .......
