Vitrail is a professioanl solvent based glass stain designed for windows or objects that are too large to be baked in an oven. Perfect for achieving stain glass effects on windows in your home or studio. Simply brush the paint on glass using soft brushes and let it dry. Colors can be intermixed to achieve a wide range of stained glass effects. The paints themselves are dry to the touch within one hour and will set up completely in eight hours. Brushes can be cleaned with turpentine or a turpentine substitute. Absolutely beautiful!
