|Here is some information that I have found. I plan on trying the first Recipe. I plan on mixing some up in the next weeks, I need to get some Beeswax still. If you get the info first, let me know at katou at echo-on.net|
A very inexpensive plasticene clay
in a one quart or two quart pot with handle
using a hot plate or an open fire add
one part Beeswax
one part Petroleum Jelly
four or five parts ball clay or any dry fine clay body ...
the softness and density is controlled by
the amount of Petroleum Jelly
and the amount of Beeswax
the clay body particles should be the finest possible within the area the user
once in Africa .. the east coast.. I used ground up dry porcelain (kaolin) clay
in Australia... on the Gold Coast... I found a wet green clay deposit.. dried
used a cement mixer with no water to grin up the clay to a powder..
and then used it to make plasticene clay
in Spain .. near Madrid.. the black clay from a studio fire
used to make a very black plasticene clay
it did not color my hands
If the particles of the clay body is to course..
it will act as a sandpaper to the hands.
Q: What is plasticine clay and how can I mix my own?
A: Plasticine is basically clay powder mixed with oil and wax instead of water. One recipe is as follows:
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 instead of wax
petroleum jelly instead of grease
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 plasticines do. Varying the proportions of the constituents slightly will yield harder or softer clays.
