Helpful Hints the things that help make marbling easier and more fun. First is mixing the marbling base and alum solution. My arm almost dropped off the first time I tried mixing everything by hand. Then I found two very helpful tools. First is a power drill. (My husband never dreamed that he would be sharing his power tools with me, but he has adjusted nicely.) The second is a paint mixer that fits in a power drill. You can get them at most hardware stores. You have just turned your power drill into a big hand mixer.

I normally mix 4 gallons of marbling base and 8 gallons of Alum solution at a time, so these two tools together make life so much easier. You may want to try it out in just plain water until you figure out the right speed. I shot water all over the place the first time. Now I don't dread the mixing of the solutions and I get a much better mix.
