LiquiStone™ is an easy to use gypsum cement that can be cast into alginate molds for reproducing human body parts for lifecasting. LiquiStone™ has a convenient mix ratio of 2 parts stone to 1 part water by volume and will have a working time of about 15 minutes. Castings can be demolded in about 3 hours. LiquiStone™ can be cast solid, or can be laid up by hand (thicker consistency required). Fully cured castings can be machined, sanded, primed and painted.
