wax/oil based sculpting clay

[Jawaid Iqbal]

I am a new sculptor. live in Pakistan.

trying to make sculpting wax/oil based clay. using following ingredients.

 

calcium carbonate.

micro crystalline wax.

Motor oil.

plain grease.

 

brblem is that the clay came out of this process is brittle and having no elasticity.

 

Help me in this... it would be a life saving. This kind of clay is not available in my city.
