I've been using dental alginates for the last forty years. My profession requires me to create life like replicas of the external human anatomy and the finished product is used by disfigured individuals as a camouflage. Thus my first task is to take a direct body cast using dental alginate of say for example: a hand from which the fingers have been amputated. In this alginate negative I pour dental stone plaster. The second direct cast is of the good hand fingers again using alginate. Into this alginate negative I pour water and then do a centrifuge spinning around myself with the mouth of the negative facing out. Meanwhile the fluid wax has been readied and is poured into the alginate negative while holding the mold at a twenty degree angle with the negative finger tips pointing down. I pour fast and change the angle of the mold as fast too as the wax is filling up. When the alginate negative is full to the brim. I may pour out the wax and repeat the process. My wax casts have the intricate skin texture and have no alginate stuck to it (whereas if I just pour in wax after removing from the skin, it dehydrates very fast and the wax will dry it further and stick to the surface of the wax) . By the way my final product is made from silicone polymer.
