Venice Turpentine is an oleo resin from the European larch tree and resembles very closely the crude turpentine of our southern pine. The crude resinous sap is prepared for use by simply driving off the moisture (water) by the aid of heat and straining. In this form it is found on the market, of pale yellow color, transparent and about the consistency of strained honey. The odor is somewhat the same as turpentine. Venice turpentine, unlike ordinary turpentine resin, does not fluoresce or turn white. It is used to some extent by decorators in sizes to give elasticity and adhesiveness and, likewise, in shellac varnishes to counteract the brittleness of that gum; also in the manufacture of sticky fly paper.
