Q: What is plastiline clay and how can I mix my own?
A: Plastiline, or oil-based modeling clay, is basically clay powder
mixed with oil and wax instead of water. Its advantage over water-based,
or potter's clay, is that it stays workable for long periods of time,
instead of drying and shriof water. Its advantage over water-based, or
10 lbs microcrystalline wax
1/2 gal. #10wt oil
4 lbs plain automotive grease
25 lbs dry clay powder (such as Kentucky ball clay)
Melt wax, oil, and grease together in an electric frying kettle; stir
clay in slowly once melted. Pour into shallow microwave-safe plastic
containers, or into a wet plaster mold.
This basic recipe may be modified for specific applications. One
variation I have worked out uses beeswax for part of the wax component,
substitutes petroleum jelly for the grease, and purified mineral oil for
the 10wt. motor oil. This smells better, and doesn't have a problem with
the rubber mold compounds I use, like most proprietary plastilines do.
Varying the proportions of the constituents slightly will yield harder
or softer clays.
