ABSTRACT:
Minute fibers are added to an alginate to form a fiber-alginate mixture or compound. The minute fibers may be man made such as nylon or may be natural such as hemp. The fiber-alginate mixture or compound is used in forming a mold, which may be used in casting directly from the human body. The addition of the minute fibers to the alginate creates enormous tear strength, which is far better than the tear strength of the alginate alone. The alginate and the fibers should be mixed in an alginate to fiber ratio by weight of about twenty-four to one for a natural fiber and a ratio of four to one for a man made fiber.
