When you mix plaster and vinegar, a chemical reaction occurs that causes the plaster to dissolve and break down. This results in the formation of calcium acetate and water. The plaster will lose its hardness and structural integrity as it dissolves in the vinegar solution.
Gypsum is heated to around 150 degrees Celsius to convert it to plaster of Paris. During this process, the gypsum loses water molecules, which causes it to transform into a dry, powdery form known as plaster of Paris.
Get a mould and plaster. Pour water into the plaster and mix. Pour the plaster into the mould and wait for it to dry. Once it is dry carefully take the plaster out of the mould and paint. Note:To get air bubbles out of the wet plaster, gently hit the mould.
Plaster does not burn but it may decompose when exposed to high temperatures, releasing steam and other byproducts. Plaster is typically made of gypsum powder mixed with water to form a paste that hardens into a solid material when dry.
100g of plaster of Paris will weigh 100g.

I general, the answer is yes. It the crack comes from the pool moving, and the gunite has cracked, then the gunite has to be repaired before the plaster. Sometimes opening up the gunite crack and refilling with concrete will answer the problem. If movement of the soil is the problem then that has to be fixed first.The soil getting excessivly wet and dry can mean that the pool will move, if it is only part of the pool then there will be a structuaral crack. Only opening up the crack will tell you whether it is a plaster crack or a gunite crack. A replaster is from about $2000 up and structuaral repairs from about $1000
One more crack like that and I'll plaster you!
