(Egg) Tempera paint?

Egg tempera paint is commonly associated with the cheap poster paint, also called tempera paint. I was also one to fall into thinking that tempera paint was the paint to avoid, and if you want to be chic and artsy, use oil based paints. But because of a recent article I wrote for my chemistry class, I was enlightened by the fact that there is hope for tempera paint! Egg tempera paint is actually one of the oldest types of paint out there. With simple ingredients of egg yolk, pigment, oil, and water, you can create your very own, durable paint. Because of the egg base, this kind of tempera paint is not affected by change in temperature or humidity. This is because egg yolks form a protective layer of film almost immediately after application. The protective layer also makes the paint waterproof, making it easy to paint multiple layers one after the other (as opposed to oil based paints that go on thick and take forever to dry). The down side of Egg tempera paint is that you have to make it yourself every time you want to use it, its not smart to try and store egg tempera paint.
