Vitrail's Transparent and Opale ultra-gloss finishes allow for subtle shades and added depth on fine art surfaces such as canvas and other non-porous surfaces. Although initially created to make the splendid art of stained glass accessible to all, these ready-to-use, alkyd oil-based paints have also revealed themselves as a unique art medium when used alone or in combination with other mediums for Mixed Media applications. Use brushes and droppers to apply the color or simply drip, spatter and pour them directly from the bottle. These paints can also be used in combination with Cerne Relief and Self-Adhesive Lead Strips for stained glass effects. Vitrail paints come in 36 solvent-based colors, declined in 26 intense and brilliant, Transparent colors, and 10 Opale bright and covering, opaque colors. All colors are available in 45 ml bottles; selected colors are also available in 250 ml bottles. Conforms to ASTM D-4236.
