Copper Penny mica is a copper color with subtle red tones that will add a metallic sheen to your soaps. It really is the color of a penny with more sparkle and shine.
Recommended use rate in cold and hot process soap is 1 tsp. per pound of oils. For melt and pour, the recommended use rate is .5 tsp. per pound of base. To use in bath bombs polysorbate 80 must be used. Use polysorbate at half your oils. For example, if you use three teaspoons of carrier oils, now use 3 tsp of oils and 1.5 tsp. of poly 80. If your bath bombs are too wet, decrease the amount of poly and carriers oil by the same ratio. The addition of polysorbate will prevent staining or a mica powder ring around the tub.
