Sculpting Head and Sculpting Figure plus Making Molds and Casting
Many sculptures are first modelled in clay and then cast in more durable material. Plaster is the main material used for making the mould. It is mixed as a liquid that flows into every detail of the clay model and then sets hard. Plaster moulds can be used to make repeats in clay or as the basis for casting in a strong material such as very high density plaster or cement.
At the end of the course students usually want to bring home their
work. For that course management will be provide instructors to teach
the students how to make moulds and produce the positives results.
For an illustration to make a print head, the positive result of gypsum material and resin or fibreglass takes three days.
While the human figure to mould with the same ingredients it takes five days. Material to make a mould which is used is cement, gypsum, silicon and resin (fibreglass). Each material has properties, techniques and different prices. Silicon is relatively the most expensive material as compared with resin and plaster. The price of resin is relatively more expensive than plaster and cement.
