Can you bake tempera paint in the oven?

Here's why:

* Tempera paint is water-based: It's made with pigments mixed with a binder like egg yolk or glue. Heat will cause the water to evaporate and the binder to solidify, potentially cracking or warping the surface you're painting on.

* Tempera paint is not designed for heat: Unlike some paints that can be heat-set, tempera paint is not meant to be baked.

* Safety concerns: Heating paint in an oven could release harmful fumes.

Instead of baking tempera paint, you can:

* Let it air dry: Tempera paint dries quickly and permanently at room temperature.

* Use a heat gun or hair dryer: For a faster drying time, you can gently use a heat gun or hair dryer on a low setting, but keep it moving and avoid direct contact with the paint.

* Use a varnish: To protect and seal your tempera paint, apply a layer of varnish specifically designed for water-based paints.

Remember: Always check the manufacturer's instructions for your specific tempera paint for recommended drying and care methods.
