At CIA we use the formulation listed below. It was developed by
Robert Buganski for his sculpture courses. Preparation is every thing.

Robert s Homemade plasticene



Ingredients amounts

Brown Victory micro-crystalline wax 20lbs,(2 ten

lb. sheets, KindtCollens, Clev.)



Paraffin wax 5lbs (optional

for hardness)



Mineral Oil 5 quarts



Petroleum Jelly 8 lbs.



OM4 Ball clay 25lbs



Foundry hill Creme 25lbs



Silica 5 lbs.



totals 150lbs

approx.



Melt both waxes together then add the mineral oil and

mixwell. Add the petroleum jelly and mix until you get an

oatmeal like consistency. Premix all dry ingredients and

then add to the mix slowly. Mix well and then pour out on

a clean water soaked concrete floor. Spread out to 1-2 inch

thickness and let cool . Cut the mix up into brownie sized

chunks and store for use. Mixture can be stiffened with

more clay or softened with more mineral oil until it is right

for your needs.



Note: the substitution of mineral oil and petroleum jelly for

motor oil make this a more user friendly, but by no means

digestible mixture. Refer to the MSDS that comes with the

waxes.
