Photographers' Formulary 10-1190 1LB Overview

Sodium Carbonate is commonly available in anhydrous and monohydrous forms. The crystalline form is available as Arm & Hammer Washing Soda, which is sodium carbonate decahydrate (use the yellow, unscented box). This can be safely substituted in almost all formulas calling for carbonate.
