Does anyone know what exactly to use when this is called for in a recipe?
Thanks for any help!

When Richard Zakin calls for a Boron Frit in his book Electric Kiln
Ceramics, he suggests using Ferro 3124 (Appendix A). Personally I would
rather he state what he actually uses in the recipies and let the reader
figure out the substitutions.

Hi:
Two of the most commonly used borax frits are Ferro frits 3124 and 3134.
They also contribute calcium, and some alumina and silica so you have to
factor that in to the glaze formula. Ferro had a frit that just contributed
boron, alumina and silica but they stopped making it and I don't think they
replaced it. I could be wrong about that though.
I could send you the analyses of these two frits if you want them.

Hi there! My guess is you are reading a British book, or got this
from a British recipe? Boral frit means a frit containing boron/B203.
Most commonly used when one is not sure is Ferro Frit 3124. PLEASE PAY
ATTENTION HERE: NOT, repeat NOT all boral frits have the smae melting
point. Therefore 15% of Boral Frit A may melt a lot lower than 15% Boral
Frit B. Therfore--unless you get your jollies cleaning kiln shelves, TEST
the glaze you are concocting on the inside of a bowl first--or set your
test tiles inside a shallow bisqued only dish something like a cat dish,
or set the test on a flat piece of bisqued clay. PROTECT THE SHELF
P.S. A lot of the British books tell you what US frits the author suggets
as Boral Frit. Hope it still is sunny in Colorado.
