Gerstley Borate substitute

Turkish Ulexite45.0
F4 Feldspar10.0


This material was developed by Plainsman Clays as a substitute for Gerstley Borate. Boraq 1 was later adjusted to become Boraq 2 (recipe also available).

The materials in the recipe are difficult to get in most places. Actually, Cadycal and F-4 Feldspar are no longer manufactured. However we make this and other recipes public as examples of how material substitutes can be formulated to emulate the physics and chemistry of others.

For more information about the logic behind this recipe and why it was adjusted to Boraq II please visit the Boraq material page at
