Bellini Sodium Carbonate anhydrous - 500g
Category: Film & Film Processing Raw Chemicals
Sodium carbonate anhydrous is used as one of the principle alkalies (accelerators) used in development formulas, sometimes known as Washing Soda, Carbonate of Soda or Carbonic Acid. It improves differentiation between exposed and unexposed crystals of silver halide, and thus reduces fog during development.
It can also be used as a toning bath additive or post fixer clearing bath.
It has a molecular formula Na2CO3.
Please note: Sodium carbonate releases a gas when added to an acid stop bath or an acid fixing bath; this gas may cause pinholes that look like blistering of your film emulsion.
