Alginate mould and wax copy taken from the mould of an arm and hand
Alginate is a salt of alginic acid, extracted from marine kelp. The calcium, sodium, and ammonium alginates have been used in foam, cloth, and gauze for absorbent surgical dressings. Soluble alginates, such as those of sodium, potassium, or magnesium, form a viscous sol that can be changed into a gel by a chemical reaction with compounds such as calcium sulfate; this makes them useful as materials for taking dental impressions.
