bag of alginate


Product code: S002

Brand:Crafty Corner

Alginate is the extremely safe molding material most often used in LifeCasting. It is an organic polymer derived from the stems of seaweed. When alginate “sets”, these polymers cross-link to one another using calcium ions as the glue, forming a flexible solid similar to stiff silicone rubber

This liquid is applied to the skin and in a few minutes the alginate “sets” to a rubbery consistency. Alginate is Hypo-Allergenic (safe) and does NOT heat up when setting. When the alginate is removed from the skin the surface of the alginate has captured every detail of the surface of the skin right down to the fingerprint. This is the mold.

Alginate sets within 9 minutes (depending on local conditions)

To produce a lifecast, a suitable casting material must be poured into the alginate mold. When the casting material “sets” or “hardens”, the alginate is removed and an exact duplicate of the body part has been produced.
