paragraphs describe the steps used to process each of the six categories of clay. Table 11.25-1 summarizes these processes by clay type. Kaolin - Kaolin is both dry- and wet-processed. The dry process is simpler and produces a lower quality product than the wet process. Dry-processed kaolin is used mainly in the rubber industry, and
