Unfortunately, genuine egg tempera paint is not manufactured commercially so you will not find it in any art supply stores. However, it is very easy to make, and in this article, we have shown you how to do it in a few easy steps. The main thing to remember when you make egg tempera paint is that it cannot be stored and used a second time. Even so, the ingredients are inexpensive and budget-friendly, so you can easily make more than one batch if required.
