Cobalt Blue Dry Pigment for Paint - 1/4 lb. / 113 grams. Mineral Powder Pigments such as oxides, ultramarines and micas are cosmetic-grade. They are approved for use in paint, soap, bath bombs, ceramics, and pottery. Our pigment can be used alone or added to other colors to deepen the tone. Recommended usage: Using scales is recommended for larger batches. Please do small test batches to perfect your process. We recommend dispersing the powders into a small amount of your base first, then add to the remaining product and stir well. It is a good idea to wear a mask, goggles/glasses and protective clothing/apron as working with volatile powders is messy. Make sure you work in a well-ventilated area. Solubility: These are natural color pigments which are insoluble (they will remain suspended within the product and will not dissolve) in the formulation or product to which they are added. Unlike some liquid colors, they will not bleed or fade. Storage: Keep your powders in tightly sealed containers or pouches in a dry location protected from light. Shelf Life: 24 months Do not consume. For external use only. Keep away from children and eyes.
