In 1920 three new pot kilns were added to the Rincon plant and the ones near the ranch house were abandoned. The Standard continuous kilns did not work well except on the dense fine-grained rock. This variety required a greater heat for complete calcination, and the use of the continuous kilns also necessitated selective mining of the limestone to provide a suitable feed. For these reasons they are not now used and all the limestone is now burned at the Rincon plant in three pot kilns. Each kiln has a capacity of 1600 barrels and is provided with four draw doors and four burners.
Fuel oil is used with steam atomization.
The barrels in which the lime is packed are made in a cooper shop at the Rincon plant. From 12 to 15 men are employed including several at the quarry and the balance at the kilns. In 1926 more than twice this number of men were at work. I. X. L. Quarry This quarry, also owned by the above company, is situated in sec. There are three pot kilns on the property.
