Just last Friday, my copy of Ron and John's book Mastering Cone 6 Glazes arrived and I can't see any reason for any other source of information! The addresses for testing glazes are in the book- as well as a few really great formulas for Cone 6 oxidation. All of the explaining of what those chemicals do- is also in the book. It really is the best, most needed glaze info. book I've ever owned. I realize many of you know about this book-but tons of glaze questions keep coming up.

What hit home for me was the suggestion that one should learn to apply a few glazes really well, instead of randomly applying a dozen!!

Anyone with any questions about cone 6 glazes -needs to get this book right away!

There are probably 10,000 glaze recipes out there that anyone can have for
the asking. Not least Cooper's book with 455, and CM way back to
prehistory, and ClayTimes since whenever they started, not to mention
Ceramic Review, and occasionally PMI.
And more books and books and books.

Just now Mark "Can any one give me the info with a phone number for the
place that tests
the glaze . I have hundreds of pounds of limestone which I was hoping I
could use for
whiting but in my glazes it makes the glaze too dry"

I wonder how hundreds of pounds of limestone sneak into one's studio, but
never mind. Nor do I know the address of the lab at Alfred--there are
others--that tests glaze.

BUT I do not see what lab testing will do, since, as Ivor suggested, the
limestone probably is not that pure. Limestone is notorious for its
variations, which is why many potters order pure calcium carbonate.

Mark: May I suggest that you make some tests upping any other fluxes in the
glazes? I am assuming you cannot calculate them so as to shorten the
process of testing. Maybe you could post some and ClayArters are bound to
make suggestions...

To get back to the student looking for recipes...what good will they do him
or her? Here is an imaginary recipe that calls for Whiting, dolomite, ball
clay, Frit 3124, silica. Here is another that calls for Wollastonite, Frit
3249, kaolin and a little talc. Could they be the same? How different
would they be? I urge the student to learn glaze calculation and/or buy a
program such as GlazeMaster (TM) which will save hours of time and much
money; to read the basic books and get a grip of what does what in a glaze
and then go out and get the recipes. There is no point in getting calling
for different materials if one does not know what the materials bring to the
glaze...
