Liquitex - Glass Medium -8oz

can be mixed with colour to create a smooth, flowy, non-drip texture, which dries to a high gloss finish and adheres to slick, non-porous surfaces like glass, ceramic and porcelain. It increases long-term surface durability, extends colour without affecting acrylic stability, and slows drying time to help you get more subtle colour blends. When heat set, this medium creates a glossy, scratch-resistant surface.
