tutorial Instructions: 1. All you need is a sharpie (oil based is best) and a porcelain white mug. (Check to make sure it is oven safe as some glazes are safe for microwaving but toxic in the oven). 2. Draw what ever you like on the mug and bake for 30 minutes at 350 degrees. (180°) 3. Cool the mugs at room temperature before washing.
