This product is for making molds of industrial patterns only. When mixed with water, Ultra Cal undergoes a chemical reaction which causes it to harden and then slowly become very hot and highly alkaline (corrosive to skin like drain cleaner.) If mixed incorrectly this process can happen very rapidly. DO NOT attempt to make a mold enclosing any part of the body using this material. Failure to follow these instructions can cause severe chemical burns that may require surgical removal of affected tissue.
