Note for wet applications: Working with fine pigments (small micron size) such as this can clump in your formula. Experienced formulators will mix the pigment with a small amount of batch material in something like a mortar and pestle. Once that small batch is colored and smooth with clumps mashed out, it is then added to the larger amount of base material. Re-ordering or love this color?
