Marabu Relief Paste is a water-based, high-viscosity paint which is applied from a tube with a fine line tip. This can be used to outline designs in relief on nonporous and semi porous surfaces such as glass, metal, ceramic, vinyl, and polypropylene. Dishwasher safe without being fired. Leave to dry for 3 days. To speed up drying time, bake in oven at 1600C for 30mins. Cleans up when wet with soap and water. Works well in combination with Marabu Glas colours.
