Sodium metaborate.octahydrate

Substitutions Balanced Alkali is a proprietary formula of the Eastman Kodak Company and is no longer being produced. However, there are many published formulas which still call for it. The composition is known to be sodium metaborate, octahydrate. Sodium metaborate is commonly sold in the octahydrate state, as it is the most stable. Therefore, weight-for-weight substitution can be made. 

Substitutions Sodium metaborate, octahydrate (8H20), and Balanced Alkali (Kodalk) are, for all practical purposes, the same. Substitution can be made weight for weight. 

Another substitution for sodium metaborate, octahydrate is to use 9 5 grams of sodium hydroxide and 45.4 grams of borax, decahydrate in water to make 1.0 liter. This is equivalent to a 10% solution of sodium metaborate, octahydrate. This can be made from Red Devil Lye and 20 Mule Team Borax and safely used in formulas as a substitute (20.0ml of a 10% solution = 2.0 grams 25.0ml = 2.5 grams etc.).
