Rublev Colours Canada Balsam Oil - 2 fl oz / 59 ml

Canada balsam is a plasticizer for varnish and paint. It can be used as varnish when diluted with a small quantity of denatured alcohol, lavender spike oil, or spirits of gum turpentine. The resin can also be mixed with drying oils (linseed and walnut oil) and other resins (copal and damar) dissolved incompatible solvents.

Canada balsam is used to prepare microscope slides and high-precision optical lens assemblies. Balsam fir gum is used for optical lenses because, when dissolved in an equal volume of xylene, its refractive index is almost the same as that of glass.
