My paintings are mainly india ink and oil colour on Gesso sottile( technical gelatine and calcium carbonates/sulphates).
I'll also sometimes use gum arabic, casein, distemper,tragacanth and a variety of waxes and plant derived drying oils . I use as my primary solvent pure gum turpentine, but in tiny quantities, mainly as a solvent for Dammar (which I'm allergic to!).
I also use a refined aliphatic distillate of petroleum and white spirit for some special purposes, I find mineral turps leaves a oily non drying residue in my paint films and gives me headaches to boot.
I'll use all pigments, including heavy metal salts, but mainly more inert ones, but treat all of them, as if they were accumulating poisons. Clean up is done with an oil rinse and Marseilles soap not a solvent.

I'm a huge advocate of lac as an interior finish, all my floors are done with button lac and wax and I've used shellac to stabilise and isolate the prior paintwork in some areas of our house before repainting (used a fairly benign acrylic that I researched, would have preferred not to, but swmbo vetoed me repainting in distemper).
