238 MINERALS YEARBOOK, 1972 drocarbons was consumed in the manufactu-re of 2,930 million pounds of carbon black. This quantity was 43.1 million gallons more than was consumed in 1971. Yields from liquid hydrocarbons in 1972 averaged 4.96 pounds per gallon, compared with 4.92 pounds in 1971. The yield from natural gas dropped to 5.02 pounds from 5.06 pounds per thousand cubic feet. Natural gas feedstock continued to decrease to 53.9 billion cubic feet, and production from natural gas declined to 271 mill-ion pounds, 51.5 million pounds below the 1971 level. CONSUMPTION AND USES Domestic sales of carbon black increased 10.3% to 3,147 million pounds. Rubber industry consumption increased 10.3% to 2,954 million pounds and accounted for 93.9% of the U.S. total. Sales for use in the manufacture of ink increased 9.7% to 82.5 million pounds. The oil-furnace-type carbon black, known as "Short Ink," was used in manufacturing ink for printing newspapers. Carbon black produced by the channel process, known as "Long Ink," was used in lithographic or halftone printing ink. Consumption of carbon black in paint manufacturing had the greatest increase, 14.5%. The volume of carbon black used in paints increased to 21.4 million pounds. Miscellaneous uses, including chemical, food, and plastics, increased 9.1% to 84.8 million pounds. STOCKS Inveistory of carbon black at yearend 1972 was 238 million pounds, 19.7% less than comparable yearend stocks in 1971. Largest contributor to the decline was thermal black inventories, which declined from 68 million to 17 million pounds. HAF and SAF were the only grades of fur- siace -blacks that had significantly higher yearend 1972 stocks than at yearend 1971. Respectively, these stocks were 14.6 million and 1.0 million pounds higher. Inventory of channel -black at yearend 1972 was 7.7 million pounds, 2.0 million pounds less than yearend 1971 stocks. FOREIGN TRADE Carbon black exports totaled 111.3 million pounds, a decrease of 51.9 million pounds from the 1971 total. Value of exports totaled $14.9 million, $5.5 million less than the value of 1971 exports. Furnace black accounted for 89% of exports. Leading recipients of carbon black produced in the United States were Canada, 19.7 million pounds; Netherlands, 16.0 million pounds; France, 13.8 million pounds; and Japan, 8.0 million pounds. These four countries accounted for approximately one-half of U.S. exports. Most carbon black imported into the United States was specialty grades. Total imported volume was 7.24 million pounds, of which 6.02 million pounds was acetylene black. Major suppliers of acetylene black to the U.S. were Canada, 5.72 million pounds, and East Germany, 0.25 million pounds. Brazil expor-ted 66,138 pounds of bone black to the U.S. Other major exporters of carbon black to the U.S. included West Germany, 0.58 million pounds, and Indonesia, 0.52 million pounds. WORLD REVIEW Carbon black production continued to increase worldwide. Decreased production was not reported for any country. Total world output was estimated to be 7.07 billion pounds. Insufficient data were available to make reliable estimates of output for several countries. (See table 11.) Japan, with an increase of 10.6%, had a high rate of growth. However, the United States, with an increase in output of 184 million pounds, had the largest volume increase.
