Fibrous plasterwork has basic methods.
Mould cutting is making a mould to form shapes in the plaster. It is a timber frame with a supportive template.
Running moulds make shapes in plaster. When the plaster has set, the shape is known as a run mould.
The moulding process is forming the shape of an item in solid or flexible materials. From this mould, the finished product will be produced (the cast).
Casting is the method in which the finished product is made from a mould.
