Abstract
Particles (10) having a selected size are produced by placing oversized articles onto a support (12) having apertures (16) of the selected size. The supported particles (10) are subjected to an etchant (22) until they decrease in size sufficiently to pass through the apertures (16), following which the action of the etchant (22) is terminated and the particles are collected. If commingled particles (10) of the selected and/or larger sizes are placed on the support (12), those of the selected size immediately fall through the apertures.
