Designs applied with the porcelain brush pens can be permanently set by heat-fixing to make them dishwasher-safe. These pens are therefore ideal for decorating any item that needs to be dishwasher-proof for everyday use.

Designs applied with gloss paint markers to a wide variety of surfaces can’t be made more durable or dishwasher-proof by baking in the oven; the ink can’t be permanently heat-fixed – but when it's dry, it will be smear-proof, water-resistant and weather-resistant on many surfaces.
