Oven curing greatly speeds up the drying time for enamel paints. Although air drying paint can take up to 21 days, oven curing can be accomplished in just hours. The heat from the oven will cause a chemical reaction that sets or binds the paint to the project. Oven-cured paint projects are much more durable than other paint jobs, and if properly stored they will last many years without fading. Certain types of enamel paint cannot be cured in ovens. Always refer to the paint manufacturer's label.

Oven Curing Painted GlassStep 1
Allow the painted item to dry completely for 24 hours before baking.
Place the painted object in the center of your cookie sheet. Make sure the painted parts of the project are not touching the cookie sheet or other projects. Place the cookie sheet on the middle rack of the oven.
Set the oven temperature to 350 degrees Fahrenheit and bake your painted project for 30 minutes.
Turn the oven off, but do not remove the painted object. Let the project cool in the oven for several hours or until completely cool.
Tips & Warnings
- Apply paint in several thin coats rather than one or two thick coats. Let the paint air dry between each coat.
- Many artists prefer to oven cure paint at night. After turning the oven off, leave the project in the oven and remove in the morning.
- Use oven curing only on enamel paint that is labeled by the manufacturer as being safe to oven cure.
- Never put painted glass objects into a hot oven.
- Do not use the painted oven-cured project for 72 hours after baking.
