1. A sorting apparatus comprising a feed, an implement, and wear tiles wherein:
the feed delivers a material to be sorted to the implement, the implement sorts the material into at least two groups based on one or more characteristics of the material including a color parameter, one of the at least two groups comprising desired product, the wear tiles cover a portion of the sorting apparatus to substantially prevent the material from contacting the covered portion of the sorting apparatus during sorting, the wear tiles having a color that permeates substantially an entire mass of the wear tiles, the color of the colored wear tiles being sufficiently different from a color of the desired product such that the wear tiles, or portions or pieces thereof, that may mix with the material are sorted by the implement from the desired product, and the wear tiles are produced by firing a composition at or above about 2500° F. from about 45 minutes to about 90 minutes, the composition being selected from the group consisting of, i.
