When working with a mold what is best clay to use?
There are different types of molds and so different types of clay work best in specific molds. Plaster molds are generally used with clay in liquid form, known as slip. In this type of mold, the porous plaster absorbs water and the solid clay is deposited on the inside of the mold, allowed to stiffen and then the mold is disassembled and the casting removed and trimmed. Slump molds or hump molds are generally used with clay slabs and the clay depends on what you are looking for in the end results: porcelain, stoneware, low-fire clay etc.
What can you use to dissolve plaster of Paris that's readily available from a hardware store or suchlike?
There is lots of bad advice on the internet to use some sort of acid, but after lots of experiments I know this to be completely wrong. Plaster of Paris is most quickly dissolved using Baking Soda in warm water.
What mineral is used to make plaster of paris?
It is made from a soft rock called gypsum.The gypsum is heated to about 1500C to remove its H2O (water) content. It becomes a dry powder, with the chemical name gympsum hemihydrate or, more accurately calcium sulfate hemihydrate. CaSO4.1/2H2O
Does plaster of Paris burn?
No Plaster of Parisis is made by calcining gypsum, a process which involves exposing the gypsum to very high temperatures to create calcium sulfate and then grinding it into a fine white powder. Gypsym does not burn and it can be used to fireproof things. The material itself is definitely non-combustible. However, it can CAUSE burns (although not chemically as lime might). When Plaster of Paris is mixed with water, the reaction is strongly exothermic. It gets warm. In large quantities it gets hot. In 2007 a school girl immersed both hands in a bucket full of wet Plaster of Paris as part of an art project. After suffering third degree burns, she had to have both thumbs and six fingers amputated.
