What is ground chalk and where would you purchase it? I have been to paint stores, art shops and places like Home Depot and noone knows what it is.

Hi Julie
Ground chalk is calcium carbonate. It comes in all sorts of forms and qualities. I got a large quantity but postal costs are horrendous.
Try doing an internet search; it might provide you with some links. For a small amount to experiment with, you could even grind up some blackboard chalk.
Decorator's merchants who sell 'traditional' materials used to sell it as 'whiting' which made a sort of powdery wall paint.

Most clerks in most craft/art supply shops aren't the most knowledgable of people. If you don't use the term they know, they tell you they don't have it.
Ground chalk = whiting = calcium carbonate. Throw all the names at them, and they may recognize one of them: "Do you have ........ or ....... or ............?"
This stuff should be as cheap as dirt. I paid $3 for 5 lbs. Retail.
Don't let them talk you into the whiting for fine art paint, which is about $9 for an ounce or so.
A potter's supply should have it where you can buy it by the pound. Try Crizmac Art Supply or Marjon Ceramic Shop, both in Tucson.
