Looking to make Marks medium mix for the first time. Went to my local art store which were less than helpful. They tried to sell me venetian turpentine and some other stuff they had. Is venetian turpentine the same thing - google sometime suggests so?
Anyway, my question, is venice turpentine what Vets use on horse hoofs? If so it is a lot cheaper to buy that in bulk from a Vet supply store than a pretentious art store.
