P-930 is a very close substitute, similarly high in Sr
and B and very close in Al and Si. I'd don't know the
glaze recipe you're working on, but I'd bet a 1 to 1
sub would at least get you a workable glaze, if not
exactly what you were expecting.

Rose, frit 3292 is:
Na2O 3.0
K2O 3.1
CaO 10.5
MgO 0.7
SrO 4.8
Al2O3 10.7
B2O3 5.7
SiO2 61.1
I don't have expansion or melting point data. I would expect that the
melting point of the F-38 is quite a bit lower than the frit 3292. Frit
3292, by the way, makes a superb cone 4-6 clear glaze all by itself. I
usually put 5-10 % EPK in it just to keep it in suspension.

Hi,
Having read Pete Pinnell's article extolling the virtues of Meredith's
Matte cone 03 glaze in the current issue of Clay Times, I was immediately
interested in experimenting with the glaze as described.
The article includes a couple of sources for the Fusion Frit F-38, however
neither source was an viable option for me. The manufacturer only sells
large quantities of the frit making the shipping on a 50 lb bag to Canada
prohibitively expensive and the other source which handles smaller
quantities, doesn't ship to Canada. After contacting a number of Ceramic
Supply stores both here and in the US, I find myself at a loss as to where
to secure the said frit.
So my search begins for a comparable frit.
One source suggests Ferro Frit 3292 as a suitable substitute and I will
surely test it. However, I was wondering if anyone could suggest another
Strontium low-fire frit that may also be worthy of consideration.
The Fusion Frit F-38 make-up is as follows...
5.5 Na2O
4.2 CaO
16.80 SrO
4.20 Al2O3
15.00 B2O3
53.10 SiO2
1.20 ZrO2
Expansion 6.18
Melting point 1550
I am very new to glaze technology and would welcome any and all imput.
Thanks for your time...

thanks for your prompt response. much appreciated.
ironic thing is, I now know of TWO frits I'm unable to get my muddy paws
on as neither is sold in any amount in Canada.
my supplier is sympathetic, however until they receive more requests for
the frits, it's unlikely they'll stock them.
..... so close and yet so far.
thanks again.

Hi Paul,
Thanks for your response. Much appreciated.
I'm trying to reproduce a cone 03 matte glaze and as the melting point of
the F-38 is much lower than the frit 3292, me thinks the P-930 suggested
by Steve Slatin may be a more likely substitute.
I will try the Ferro frit 3292 as a higher temperature clear glaze.
thanks again,
rose bauer
