potassium carbonate is a salt of tartar (E501) used in cooking as a leavening agent. it allows us to saponify the wax to make wall wax which is diluted with water. potassium carbonate is harmless to health and the environment.
manufacture of saponified wax with potassium carbonate to wax your paints and coatings:
- put 100gr of white beeswax and heat over low heat to melt.
-Add 1/2 liter of hot water and 60gr of potassium carbonate. boil, stirring continuously
-Add 60gr of Marseille soap shavings. turn off the heat and stir until the soap is completely mixed
-apply with a brush and spread out well to avoid the white marks that the soap could make, without making any extra thickness.
- wait for complete drying and polish.
This method is however less effective than saponification with ammonium carbonate, however it does not release ammonia vapors (against which precautions must be taken, as these are harmful to health)
potassium carbonate is also used in cooking as a leavening agent and as an acidity regulator and stabilizer in food preparations.
potassium carbonate can also be used in organic farming to fight against powdery mildew.
