 1 Includes limestone and oysterahell ured in cement and lime as follows
(in thousand short tons and housassi dollars): 1963, 13,242 tons, $13,580;
1964, 13,657 tons, $14,226, 1965, 12,993 tons, $13,870; 1966, 12,171 tons,
$14,000; 1967, 11,593 tons, $12,911. 
 2 Includes light-colored volcanics, schist, serpentine, river boulders,
and such other stone as cannot properly be classed in any main group; also
marble and slate. 
 
nage increases reported for rubber, paint, and insecticide uses. Comparatively
high average unit prices led to the use of substitute materials, such as
diopside from an Arizona mine, for ceramic use. Exports (all talc) totaled
nearly 1,000 tons. 
 All pyrophyllite mined in 1967 caine from San Diego County deposits although
shipments were made to grinders from stockpiles in Mono and San Bernardino
Counties. Mines in Inyo and San Bernardino Counties yielded all the State's
talc and deposits in Amador, El Dorado, and Los Angeles Counties, all the
soapstone. 
 Grinding plants were operated in 
Alameda County (talc and soapstone), El 
Dorado County (soapstone), Inyo County 
(talc and soapstone), Los Angeles County 
(talc and soapstone), San Bernardino 
County (talc, soapstone, and pyrophyllite), 
and San Diego County (pyrophyllite). 
 
 Other Nonmetals.—Chas. Pfizer & Co., Inc., produced natural and
manufactured iron oxide pigments in an Alameda County plant, the only such
facility in California. Output was 5 percent below that in 1966. Declines
were reported in all categories except manufactured yellows. Basic raw material
for the natural products came from out-of-State sources. 
 Phosphate rock from Idaho mines and pebble phosphate from Florida were shipped
to chemical and fertilizer plants in Contra Costa, San Francisco, and San
Joaquin Counties. Pebble phosphate ship- 
ments into the State rose 44 percent but receipts of phosphate rock from
Idaho by California consumers were nearly 8 percent lower than in 1966. 
 Vermiculite exfoliation plants were operated in Alameda and Los Angeles
Counties by California Zonolite Co., using crude ore received from the company
mine in Montana. La Habra Products Co. exfoliated crude vermiculite, imported
from the Republic of South Africa, in its Orange County plant. Plant products
were used chiefly for lightweight aggregate in plaster and concrete, thermal
and accoustical insulation, and a soil conditioner at nurseries. All sales
except those for aggregate were higher than in 1966. 
 Wollastonite was mined from an open pit near Spanish Springs, Inyo County,
by International Pipe & Ceramics Corp. and near Blythe, Riverside County,
by Chas. Pfizer & Co., Inc. In both instances the mineral was used in
ceramics. Float wollastonite collected in previous years for use as building
and ornamental stone, was not collected in 1967. Total production dropped
substantially. 
 Western Industrial Minerals made a test shipment of kyanite from its Bluebird
No. 1 claim, Imperial County, to a prospective customer in Colorado. 
 In Antelope Valley, Kern County, Great Lakes Carbon Corp. operated furnaces
to produce synthetic graphite used in making anodes, electrodes, and crucibles
and other vessels.
