The procedure resembles that used for colored classroom chalk but calcium sulfate is used instead of calcium carbonate In addition the dry material is mixed with clay and oils and more pigments are added to produce a slurry that has the consistency of toothpaste Because the final products must be relatively moist pastels are usually air dried rather than bakedCalcium Carbonate continuous digester kraft process scale control scale guard Introduction Calcium carbonate scaling of digesters and black liquor evaporators is the most frequently identified inorganic deposit problem in the kraft cycle Scale buildup on heat exchangers leads to increased steam usage in the digester and reduces production of strong black liquor at the evaporators
