DecoArt Blue Glass Paint Marker allow you to easily paint on glass, porcelain, glazed ceramics and metal to add your own unique finish with the ease of using a marker pen. The markers dry to a glossy translucent finish and are easy to apply with the durable 1mm fine nib. They are water based and non-toxic but should not be used where there is direct contact with food. 

Just allow them to air cure for approximately 8 hours then bake at 190°C (375°F) for 40 minutes to give them a dishwasher-safe finish.

After use just wash up with soap and water whilst still wet.
