Available in 48 colours spread across 2 series of pigment grades. Winsor & Newton Alkyd oil paints dry very quickly allowing the artist to work more productively on a single painting. It has all the benefits of both oil and acrylic making this type of media fantastic to work with. Griffin alkyd oil's have a slighty greater level of transparency for better depth, they are slight more fluid than traditional oils and dry with a slight glaze. You can use this product on any surface which accepts an oil based paint, this includes canvas, paper, board e.t.c. Alkyd oil can be mixed with ordinary oil paint, doing so will alter the time at which the product dries depending on how much of each type of paint you have mixed together.
