FYI a discussion of Venetian Turpentine. It is a resin/balsam extracted from the Larch tree, Larix decidua, Pinaceae.
HereNOTE: "There is a product called Venice Turpentine that is used for treating horses’ hooves and is a dark brown sludge because it is just rosin dissolved in a solvent. Rosin is the solid residue left after a resin has been distilled to yield the essential oil or spirits of turpentine; it is a very poor material and should not be used for oil painting."
The ingredients list for Hawthorne Venice Turpentine, Pinus Palustris (Gum)- 65%, Turpentine Essential Oil (Larix decidua)- 20%, Mineral oil- 15%, confirms the point. 65% rosin.
So the Hawthorne product doesn't appear to be 'proper' Venetian/Venice Turpentine.
True Venetian Turpentine isn't cheap! Luckily not much is needed.
