Gamblin Cold Wax Medium
Gamblin Cold Wax Medium is a mixture of natural beeswax (wax pastilles), Gamsol Odourless Mineral Spirits and a small amount of alkyd resin. This versatile medium can be added directly to oil colours as a painting medium, used to modify the surface quality of Gamblin Galkyd painting mediums, as well as used alone as a matte varnish.
The term “cold” in Cold Wax Medium and Cold Wax Painting refers to the fact that heat is not required for working with this wax medium – as it dries by solvent evaporation (Gamsol), rather than the cooling of the wax, as in encaustic painting. As the Gamsol evaporates out of the medium, the soft wax hardens to the density of a beeswax candle. Unlike other Gamblin painting mediums, which increase the flow and gloss of oil colours to varying degrees, Cold Wax Medium makes oil colours thicker and more matte.
