Due to the very high price of venice turpentine in Brazil, since I can only import and the fees are high, an art teacher suggested (via facebook) to replace it with dammar varnish, since it would work approximately in the same way.
"If you want to replace the venice turpentine, you could consider just leaving it out, or maybe using more stand oil, or maybe substituting dammar varnish, but I have no idea what sort of proportions to use"
Note that Mark Carder himself approved the comment. Another problem is that I only have access to the dammar in liquid form, which means that it already has solvent and I will need to consider this during mixing. And pure clove oil costs, proportionately, six to twelve times more than paint, so it does not make sense to use it in the medium and I'll just add small amounts to each pile so it will not dry out while I'm using it, maybe three or four days.
So as I have never even seen the venice turpentine (yes, I searched at veterinary stores) I would like to know how consistent it is so that I can reproduce a medium with similar physical properties with SDM. I suppose it's something between the damar and the linssed stand oil.
Thank you all!
Ps.: sorry for my english
