ABSTRACT:
An apparatus and method for artificially weathering large amounts of marble by use of a horizontally disposed drum having a stone lined interior surface. The drum houses a large quantity of marble having similar surface hardness together with a slurry of abrasive material including silica, clay, and gravel which operates to cushion the marble from chipping during tumbling of the marble. The stone lining of the drum absorbs the impact of marble to reduce or prevent chipping of the marble. The marble and slurry are rotated at a particular speed for a predetermined amount of time. Various types of acid can also be inserted into the mixture providing a faster processing time and surface etching not possible with straight abrasion techniques. The processed marble is removed from the drum and sliced in half so to provide two pieces of weathered tile each having a flat mounting surface.
