This didn't get posted last week (I guess), here goes again:
What are frits 54(pemco), 3223 and 25? Where can I get them or what could
be a substitute? I found them in Behrens book of Glaze Projects - would
really love to try out these simple glaze recipes. These frits are all used
in a low fire glaze.
This is a big question on my mind. I use white earthenware (Laguna Em210).
(I usually bisque to 05 and glaze to 06)
I desperately want to make casseroles and my supplier told me if I just
bisque to 02 this body would work. The Laguna consultant also said this
body should be oven and microwave safe, even bisquing at lower temperatures
(I fould that applying the glaze after an 02 bisque is much more
difficult). I have taken to throwing in a handful of sand to make this body
a bit more toothy and sturdy - and durable in the oven. But I have always
heard(right here on this list!) that white earthenware was NOT indicated as
ovenware, due to poor tolerance of thermal shock.
PLEASE give me your wisdom on this, my head is so confused!
(BTW- I am testing my results with food in the oven and microwave with good
results so far...)

Hi Sharon: I have % and molecular analysis for most frits. 3223 is a Ferro

Ferro could provide you with a substitute. Ferro Corp., Coatings Division,

You might check with your local suppliers before making and long distance
calls. Most Pottery Supplies carry a good stock of frits.
