 THE MINERAL INDUSTRY OF PENNSYLVANIA 453 
REVIEW BY NONFUEL MINERAL COMMODITIES 
NONMETALS 
 Cement.—Nationally, Pennsylvania ranked first in 1979 in the production
of masonry cement and third, behind California and Texas, in the production
and production value of portland cement. Masonry cement was produced at 17
plants in 8 counties. Compared with the data for 1978, shipments in 1979
decreased, but value increased. 
 Portland cement was produced at 17 plants in 7 counties. Shipments and production
value decreased in 1979, compared with the data for 1978, owing to a decline
in the housing and construction industries. The leading producing counties
were Northampton and Lawrence. Other producing counties included Allegheny,
Berks, Butler, Lehigh, Montgomery, and York. 
 Major producers of portland and masonry cement included Amcord, Inc., Coplay
Cement Manufacturing Co., Medusa Corp., National Gypsum Co., and U.S. Steel
Corp. There has been little change in use patterns 
during recent years. Of the 6.5 million short tons of cement sold in 1979,
approximately 54% was used by ready-mix companies, 28% was used in concrete
products, 12% was used by building supply dealers, and the remaining 6% was
used for other purposes. 
 Clays.—During 1978, 36 companies operated 85 clay and shale mines
in 23 of Pennsylvania's 67 counties. The industry's structure was similar
in 1979, but the production of clay and shale decreased in comparison with
that of 1978. Clearfield County, with 12 operations, was the leading producing
county. Other major counties, in descending order of production, were Lawrence,
Berks, Beaver, York, and Armstrong. 
 The average unit value of clay and shale increased to $7.42 per short ton
in 1978, and unit values continued to increase in 1979. Clay and shale were
used mainly in the manufacture of face brick, firebrick, cements, flue linings,
refractory products, and sewer pipe. Leading producers were GlenGery Corp.,
Medusa Corp., Hanley Co., and Resco Products, Inc.

 Graphite.—Airco Speer Carbon Co. and Stackpole Carbon Co. (both
in
Elk County), and Charles Pfizer & Co., Inc. (in Northampton County),
produced synthetic graphite for use in the manufacture of anodes, graphite
shapes, crucibles and vessels, and electric-motor brushes. 
Gypsum.—Imported gypsum was calcined 
by United States Gypsum Co. in Philadelphia County. Calcined gypsum was used
mainly in the manufacture of prefabricated prod- 
ucts, such as regular wallboard, type-X wallboard, and lath. These products
were used extensively in home and commercial construction. 
 Iodine.—Whitmoyer Laboratories, Inc., in Lebanon County, and West-Agro
Chemical, Inc., in Washington County, imported crude iodine from other States,
which was used in the manufacture of pharmaceuticals, catalysts, and sanitation
products.
