Where can I find calcium hydroxide?

I am going to grind my own blue corn and the recipe calls for calcium hydroxide (1 TBSP to 1 pound of corn, boil for 15 minutes, soak for several hours, rinse well, dry and grind). I did not want to spend over $100 for a grain mill but may think about a Kitchen-Aid attachment if hand grinders look too flimsy. Biggest problem I've run into is trying to find a source for the Ca(OH)2. Any help or suggestions would be appreciated. Bob

And you can find it in Latin American grocery stores, sometimes called "powdered lime". This link shows a packet of calcium hydroxide used for making fresh masa, http://www.mexicoinmykitchen.com/2009/01/how-to-make-your-own-home-made-fresh.html
