Fellow Potters:
I'm new to Clayart and this is my first post so be gentle with me...
My question is: I have a recipe for a glaze (Raku process) which calls for
frit 3110. I have on hand frit 3119. What is the difference and can they
be interchanged? TIA

>Dan,
I don't see 3119 listed. Are you sure of what you have? At any rate,
unless you are going for a specific color, ie. Egyptian blue, you can make
a raku base glaze with gerstly borate 80%, and Neph sy 20%. Then add your
color, or you can use this as a crackle by itself. Frits can get expensive,
but a few low temp frits you could use for raku can be, Ferro 3110@1600
degrees f, 3134 @ 1450 deg. f, 3195 @ 1500 deg f, 3278 @ 1400 deg f. These
melt temps are relative. One advantage to frits is you get uniform melt, and
with gerstly borate you can get alot of bubbling before it smooths back out.

Anyone got info on 3119?

I thought that i had info on most frits. But, i don't have anything on this
one.. can someone help with Ferro Frit 3289..Thanks.... Jim

Jim- You can find the info you are looking for on the materials data list on
the sdsu site: art.sdsu.edu/ceramicsweb. I just tried it. Good luck. Linda

Here you go, Jim.
BaO .67 Na2O .33 B2O3 .67 Al2O3 .20 SiO2 3.07
If you can use this, meaning you have a glaze with barium carbonate and
an equal molecular amount of boron, you will notice some differences in
your fired result (maybe- as usual, it depends). Barium carbonate
requires reduction, even a tiny bit, to really kick all the carbonate
loose from the BaO. So if you're firing in reduction, you might not
notice much difference in the glossiness of your glaze. But if you're
firing oxidation, you may find that an exact reformulation of your
recipe may be glossier using this frit. Parmalee says that Ba
introduced in the form of carbonate is about as fluxy (is that a word?)
as calcium, but introduced in the form of a frit it's almost as fluxy as
lead. This is in a discussion of why it will not be possible to invent
a single viscosity index number, because the Seger formula has no way of
accounting for phenomena like this or particle size of raw materials.
By the way, this frit will not work as a substitute for barium carbonate
in a glaze without the equal amount of boron. For that I use frit
CC257, which has the Ba but not the B. I've pretty much stopped using
BaCO3 in my Ba glazes, not for safety reasons, because it doesn't really
make any difference to the fired result, but because it's so much easier
to get the frits to mix with the other ingredients without being lumpy.
Happy testing,

Does anyone know the number of a "calcium borate" frit that would work at
cone 9-10? I'm asking for a friend. Thanks.

I have a recipe for a Raku glaze that appeared in Clay Times that calls =
for frit G F 136 or Ferro Frit 3819. The problem is i can not find that =
frit. I checked the frit website and it does not list a substitution. =
Please help. Thank you . Betsy Cox .

Betsy, try Ferro frit FF 3269. It is almost the same as 3819. Enjoy! Les H.

When I was in elementary school my teacher pinned a note to my shirt for my
parents to read. It said, 'Charlene is not coloring inside the lines.' My
parents contacted the teacher and asked the teacher what the purpose of
coloring inside the lines was.' The teacher didn't quite know what to say,
except that the direction she had given was to color inside the lines. My
dad told me to color any way I wanted to and when I was done coloring, to
draw a black line around my picture." Charlene Felos, Ceramics Instructor -

Hi,
I am looking for some any available frit #3247, barium frit. If anyone has
any available for purchase, or other whereabouts to find it please let me
know.
Thanks,
