Nature Curriculum prototype: Natural paint.


For my prototype I made paint out of a red and yellow soft rock (maybe sandstone?) That I  gathered from the desert.

Recipe:
crushed rock (for pigment)
1 egg yolk (to act as a binder)
1/4 teaspoon water

1) crush your rock in to a fine powder in a bowl, using a stick or some straight tool.
2) If you are crushing multiple rock colors, mix the colors you want  by mixing the powders together. 3)Set powder aside.
4) Separate egg yolk form the egg white.
5) Place egg yolk and 1/4 tsp. water in a clear bowl. Mix together well.
6) Mix in rock pigment powder. mix well.
7) Paint!
8) To preserve the paint, keep refrigerated.
