1. A method for making abrasive particles comprising:
forming a mixture into a body wherein the body is in the form of a layer, wherein the mixture comprises a ceramic;
deforming at least a portion of the body to create at least one crack initiation point, wherein deforming includes contacting a form to a surface of the body;
drying the body under controlled cracking conditions to fracture the body into a plurality of precursor abrasive particles, wherein controlled cracking conditions include controlled crack propagation from the at least one crack initiation point; and
forming the precursor abrasive particles into abrasive particles, each of the abrasive particles comprising a body having a first major surface, a second major surface, and a side surface extending between the first and second major surfaces, and wherein the side surface comprises an irregular two-dimensional shape as viewed in the plane of the first or second major surfaces.
