There are many different types of casting materials available to suit many different types of projects.



If you are creative with jewelry then you may wish to look at the various resins for casting unique resin jewelry pieces. If you are after a fun and creative party activity for children then you may want to investigate the casting of plaster ornaments and plaques for them to paint. Plaster is the most ideal casting material for this purpose. Every project has its own requirements and here we will look at the most popular casting materials and their uses.

GYPSUM PLASTERS

Gypsum plaster is a versatile, cheap and safe casting material to use for many different types of applications. This material only requires an inexpensive latex mold rather than more expensive silicone rubber mold making materials which are generally needed for resin castings.

Casting plasters are best suited for general purpose art casting such as for children's plaster painting ornaments. Casting plasters have a harder surface which prevents chipping and provides a good surface for painting. Whereas, plaster of Paris, is hydroscopic, chalky and too soft for casting; it is best used for its intended purposes – wall patching.

For projects that require a harder and more durable plaster casting material you might want to look at one of the stone plasters. These are more expensive but the strength is superior.
