There are about 10-15 types of plaster. Plaster of Paris is a craft line. It is extremely porous so cannot be used as a container to hold a moist product because it will drink the fluid. When it is hard it is like a chalk. You see little figurines made of it and people paint them.
It is a power when you buy it. To mix, You put the water in a bucket, add the plaster not too fast because it needs to be absorbed by the water DO NOT STIR IT while you are adding the plaster to the water. If you stir anything after than will lump. Continue adding plaster until all the water is gone (plaster sinks to the bottom) This is a perfect mixture and you can pour it into a mold and wait for it to harden As it hardens it will heat up so it is not too good to put on your skin. It is still fragile as long as it feels cold to the touch.
Now if while you are mixing and you see you started with too much water, you can tilt the bucket and pour off some of the water. Then add enough plaster to absorb all the water. Then you can stir it and pour.
Most hardware store carry plaster in one pound containers, but it is also available in bags up to 100 pounds. Pottery store sometimes will carry the larger bags.
Oh Yes, do not pour it down the drain, it will settle in the trap and it will harden underwater and clog.

plaster of Paris is too soft to use for bowls. You may think of clay. You have to fire clay in a kiln (an oven is not sufficient) to make it hard and you also need to glaze it if you use it for food.
If that's not what you mean rephrase your question so you actually form complete sentences which make sense.

a type of building material based on calcium sulfate hemihydrate, nominally CaSO4·0.5H2O. It is created by heating gypsum to about 150 °C.

it is for sculptures and molds (but not molds of the human body because it heats up as it dries)
