• Includes ardmorite, bentonite, black-burning clay, montmorillonite, and shale; clay for architectural terra cotta, artificial abrasives, art pottery, asbestos products, blast furnaces, building brick, coke ovens, cosmetics, decolorizing oils, flower pots, foundries, gas retorts, greenhouse-glass coating, high-grade tile, hollow building tile, insecticides, medicines, modeling, paint, pencil leads, plaster and plaster products, roofing tile, sewer pipe, soap, and steel castings. Slip clay is also included in this column as a matter of statistical convenience.

These totals include 8,520 tons of slip clay valued at $43,609, or $5.12 a ton, from Michigan (630 tons valued at $3,284) and New York (7,890 tons valued at $40,325).

Forty-two States reported clay sold as such in 1923, an increase of 1 (Arizona). The leading 10 States in the order of quantity sold were Pennsylvania (15 per cent of the total for the United States), Missouri (14 per cent), New Jersey (11 per cent), Georgia (9 per cent), Ohio (9 per cent), California (8 per cent), Colorado (6 per cent), Illinois (5 per cent), and Tennessee and Kentucky (3 per cent each). These ten States reported 83 per cent of the total output, and the first five reported 59. per cent. In all these States except Georgia fire clay is the leading kind reported, constituting from 51 per cent of the total output in California to 99 per cent in Missouri.

PRODUCTION BY USES

Statistics showing the production of clay by uses are necessarily incomplete, as many clay miners do not know the purpose to which their clay is put, but it is believed that the figures given in the following table are sufficiently complete to serve as a guide in the study of the uses of domestic clays. In considering these figures it should be borne in mind that they represent chiefly the clay sold as clay by the original producers and do not include the much greater quantities of clay that are burned into clay products by those who mine their own clay.

BARYTES AND BARIUM PRODUCTS1

By C. E. SIEBENTHAL and E. R. PHILLIPS

The value of the domestic crude barytes sold in 1923 was $1,664,156, as compared with $1,123,950 in 1922. The value of the barium products made from both domestic and foreign barytes was $13,735,184, as compared with $11,399,441 (revised figures) in 1922. The industry thus made a notable advance from the slump of 1921. The material sold, or shipped or used, is taken to represent the output.

CRUDE BARYTES

SALES

From 1901 to 1915 the output of domestic crude barytes ranged from 37,000 to 109,000 short tons, and the average was approximately 56,000 tons. The war cut off the foreign sources of supply and thus increased the demand for domestic ore, and the annual output from 1916 to 1920 averaged about 204,000 tons. The shipments of crude barytes from mines in 1923 were 38 per cent greater in quantity and 48 per cent greater in value than in 1922 and were exceeded in quantity only by the output of 1916 and of 1920.
