1. A method of forming a uniquely identifiable unit of a meltable material, the method comprising:
melting a unit of the material to a liquid state;
injecting a second material into the unit of material while the unit of material is in liquid state to form a unique spatial pattern of shapes inside the unit of material, wherein the second material is injected with a nozzle configured to inject the second material at minimum of 5 pounds per square inch (PSI) with pressure increasing until the unique pattern of shapes in the unit of material is formed;
cooling the unit of material to solid form while retaining the unique spatial pattern of shapes created by the second material internal to the unit of the material; and
recording the unique spatial pattern of shapes created by the second material internal to the unit of the material using a non-invasive method so that the unit of material can be positively identified among other units of the material that appear externally identical.
