The sand quarry of Puiselet operated from 1924 to 1944. Here, the remains of a wagon that was used to transport the sand outside. The sand in the region of Fontainebleau (Nemours) is a very pure sand and very fine. As one of the highest quality sand (rich in silica at 95%), it is used for optical camera or glazing prestige (The Louvre pyramid for example).
