How are watercolors formed?
They are made from pigment and gum arabic.
How do you mix gum Arabic solution for lithography from powdered gum Arabic?
Long answer: Get 400 grams of gum Arabic powder and dissolve it into a liter of water. Put your hydrometer into the gum solution and add more water until it reaches 14 degrees Baume. You then have to add about half an ounce of Listerine as a preservative. Make sure it's the regular old yellow Listerine, not mint or some other brand of mouthwash. Real answer: Why bother? Most of us buy it premade.

Yes that's about it. I just saw an answer on answerbag.com that was very detailed, I suggest you go there.
