Pros & Cons The white shows less blemishes, the darker the finish the better the heat wil be kept but the greater the potential algae growth
There is no specific element in plaster that produces. The chemical reaction that results when plaster is mixed with water is what produces the heat.
If there is water in it you can heat it.
Yes. Black is way better than white because it absorbs heat whereas white reflects it.
It produces an exthermal heat
Because white reflects the heat from the body, whereas black absorbs the heat in
White surfaces reflects light - black absorbs it
Plaster of Paris is a classic exothermic reaction. The gypsum when heated to 150 degrees dehydrates with 75% of water content escaping as vapor. When water is reintroduced it resets the crystal lattice and gives off heat.
Yes, but not directly. The hydration of calcium sulfate into gypsum is a molecular change that requires significant heat (150° C, 300° F) to again dehydrate the powdered plaster. (When dry plaster is mixed with water, it releases heat through crystallization.)

White! Because it would be really hot if you wear black, black absorbs heat.
