I've been looking at Greg Daly's book GLAZES AND GLAZE TECHNIQUES. In his mid-fire glazes he's using frits for which I can find no reference. Does anyone know where I can get a comparison chart that contains his frits. He uses Frits, 4064, 4110, 4113 and 4364.

These are Australian frits and he gives the analysis in an addendix. I'm looking for a cheat sheet that relates these frits to US frits.

Any Ideas????

Thanks

I have this book and tapped inside the cover is this info ..
1.Austrailian ferro #4064 equals US ferro #3626, which is discontinued so
use either a lead bisilicate or ferro 3403 which is a monosilicate and a
little softer and more fluid and melts at a lower temp.
2. Austrailian ferro # 4110 equals US ferro #3110
3. Austrailian ferro # 4113 equals US # 3124

Hi Bob,

When I bought my copy of Daly's book I was given a sheet by the supplier I
bought it from, which gives the following conversions :

Australian Ferro 4064 -> American Ferro 3626 which is discontinued.
Use either
a lead bisilicate or Ferro 3403 which is a monosilicate and a little
softer and
more fluid and melts at a lower temperature.
Australian Ferro 4110 -> American Ferro 3110
Australian Ferro 4113 -> American Ferro 3124

Actually I note that the same conversion is given in Daly's book in
Appendix 1
(never checked before but it is there), except that it quotes 4064 -> 3026.

I see no conversion for 4364 I'm afraid nor an analysis to start
from. Contact
Ferro for the 4364 analysis is probably the only option. I can't see it
on their
website, though they can be emailed for info. If you search the web you
can find
unity formulae for it, but who knows if they are the same thing or not. They
don't look too bad. Could be a place to start. 4064 is suggested as a sub in
one place (clayart archives http://www.potters.org/subject19090.htm), and its
close (to what I found elsewhere) but it has a little additional soda. There
are some other refs on the web too, but its probably best to get the analysis
from Ferro and work from that.

I just checked these against Insight analyses for these frits and
they are not
spot on, though close. Could not check the first one, but the second and third
(3110, 3124). Anyhow, I would probably reformulate the glazes starting with
these frit subs, if it did not look good in tests, or do it outright.

Hope this is of some help.

Thanx
D

Hi Bob,

Greg give the "cheat sheet" for 3 of them right on page 137--the next
page after the analyses.

Regards,

John

I believe that the old 4364 was changed to KGF4064.
For Australian potters, it is similar to the old Cesco 64.
The composition was given as:
Na2O 0.051 Al203 0.064 Si02 1.744 Pb0 0.949

Cheers. Graeme.
