Pink House Studio's offers Slow-Set and Regular-Set Algiform. Slow-setting alginate may be mixed with warm water and will still allow 8-10 minutes of working time. It is used in a slightly different way than traditional alginate. Perfect for body casts when the cold water used with traditional alginate causes unwanted goose bumps. Regular-set is a cool water alginate with a working time of approximately 3 minutes. The least expensive alginate we sell!
