master frit substitution chart (?)

Greetings all Mud Buds,

Welcome back from the Labor Day holiday! Only in America do we have a
special day of no work, called Labor Day, during which we work like mad! We
mow lawns, wash cars, do yard sales, clean our houses and places of worship,
and (some of us) sweat like crazy in a hot studio, fabricating and glazing
pots. "Labor Day," indeed! :o)

A question for all our international Clay Mates--North American, European
Union, Middle Eastern, EVERYBODY gets a part of this one. My personal
experience in North America is with Ferro frits, mostly. I have used Pemco
and Hommel frits, but mostly Ferro. Mainly because, for me, they are the
most available frits and easy to purchase.

I have several books published in the United Kingdom which list
Potterycrafts and Potclays brands of frits in several recipes. I would like
to test these recipes, but do not have ready access to these materials.

I have found several websites that list comparisons and substitutions for
Ferro--General--Pemco/Mobay/Bayer--Fusion--O. Hommel frits, but have had no
luck finding any cross-references to Potterycrafts and Potclays frits
substitutions.

Can any of you add more pieces to this puzzle? Is there an elusive "Master
Frit Substitution Chart" somewhere? Either in print in a book, or on-line
will do.

Thanks in advance,

Tig

Emmanuel Cooper and Derek Royle in their GLAZES FOR THE STUDIO POTTER have,
on p.173 analyses of British frits. The book is published by B T Batsford
Ltd, 4, Fitzhardinge street, London WIH OAH, but I am sure I bought mine
from Steve at The Potters'Shop.

By the way this is a book that everyone should have. Hope its still in
print.

Also: in many books --as in Harry Fraser's Glazes for the Craft
Potter--another indispensable esp. for novices, also British, but
available--they speak of Boral Frits, Alkaline frits. By looking at a US
frit chart you should find a plethora of boral frits, and a few boron free
alkaline ones.
(I think the P283 we have been going on about is one of the latter, but I am
not certain, have to check.)Test your proposed glaze with one or two of the
availables, and you should land in the ball park.

And as I am sure Potterycrafts are as wonderful as ever, why not drop them a
line and ask if you can have the sheet with their analyses?
