Griffin Alkyd Fast Drying Oil Colour is a genuine oil colour made from pigment and oil modified alkyd resin which can be thinned using conventional oil colour solvents. It is this unique formulation which allows Griffin Alkyd Fast Drying Oil Colour to dry quicker than most oil colours but slower than acrylics. This means that the traditional oil techniques of both impasto and glazing can be done in considerably less time and a painting can be completed in a single session. All colours in the range remain workable on the palette for 4 to 8 hours and are touch dry on the canvas in 18 to 24 hours. The drying time; however will be affected by the thickness of the paint and the temperature of the environment. Titanium White is a clean white pigment. It is the most opaque white pigment and is considered a standard strong white colour.
