The fine, white clay mined near here was used at this shop from the 1840s to 1912 to make pitchers, jars, crocks, churns, flower pots, and ornamental urns, which were used locally and shopped out of county. In the 1870s the shop, built by Alberry Johnson, was a major industry in Pottersville (later Oletha) Wm. C. Knox later bought the plant and hired J. L. Stone as the chief artisan. John Fowler then became owner and was joined by his son E. J. Fowler about 1900. Men dug kaolin clay from pits and hauled it to the plant, where mules provided labor to grind the clay to powder and it was fashioned into ceramics. Historically, kaolin -- still mined today from the deposits nearby -- has been used to make fine porcelain and china. It ranks with gas, oil, and stone as a major commercial resource in Limestone County. During the 19th century, vast natural resources throughout the state were creating new enterprises. Cattle and cotton headed the list of products, which also included lumber, iron ore, stone, and salt, as well as finished articles such as cloth, iron kettles, soap, flour, brick, and matches. These businesses, although crude and not of the "luxury" type, initiated the industrial growth of Texas. (1967)
