The best thing about Firecracker mica is the way it looks in clear melt and pour. It is a true, bright red. If you are looking for a true red for your melt and pour soaps, look no further. In cold and hot process it fades to a very pretty bright pink color.
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 oils, now use 1.5 tsp polysorbate 80 and 1.5 tsp. oils. The addition of polysorbate will prevent staining or a mica powder ring around the tub.
