Product Highlights
  • Ideal Substitute for Sodium Carbonate
  • Alkali Accelerator for Developers
  • Produces Warm Tones in Paper Development

Potassium Carbonate Anhydrous from Photographers' Formulary can be used as an alkali accelerator in concentrated developer solutions. Due to its higher solubility, it is an effective substitute for sodium carbonate, where 13 parts by weight of potassium carbonate are equivalent to 10 parts per weight of sodium carbonate, and will help to achieve warmer tones in paper development. When substituting potassium carbonate anhydrous for sodium carbonate monohydrate, multiply the amount of sodium carbonate monohydrate needed by 0.90.

This item is one bottle containing 1 lb of potassium carbonate anhydrous.

Synonyms Carbonate of potash
Pearl ash
Salt of tartar
Salt of wormwood
