Sand of Toulouse

The sand generally considered good is the one found in a vineyard near Pech—David. But the best is the one is from the Touch, a river close to Saint—Michel and Blagnac, in a vineyard at a high altitude. This sand is thinner, and a bit greasier than the other, and better for small works. It should not be overheated.
