Stockton Fire Brick Company, Livermore Plant
Gladding, McBean & Company, Livermore Plant
History
In 1937, the Stockton Fire Brick Company purchased the closed plant and property of the
Livermore Fire Brick Works after it was abandoned by W. S. Dickey Clay Manufacturing
Company of Kansas City, Missouri. This brick plant stood on Stanley Blvd. at Railroad
Avenue, between the Southern Pacific and Western Pacific railroads on the west side
of Livermore. The Stockton firm used the Livermore plant to supplement the manufacturing
of its own line of fire brick at the Stockton plant in San Joaquin
County and the Pittsburg plant in Contra Costa County. Fire clay was shipped by rail
from Amador and Placer counties, where the company either owned or leased clay pits.
The process and equipment used were the same as used by the former Dickey Clay Company.
Although I have not been able to verify all of their bricks yet, it is possible that
the Stockton Fire Brick Company made the Stockton, Carnegie, and GASCO brand
named fire brick at the Livermore plant. This plant produced only fire brick.
On December 11, 1943, the Stockton Fire Brick Company was acquired by
the Gladding, McBean & Company of Lincoln, California. The Gladding, McBean &
Company continued the production line of fire brick at the Livermore plant to
supplement the Pittsburg plant in Contra Costa County, which it also had acquired from
the Stockton firm. The fire clay was shipped by rail from Placer and Amador counties,
where the company owned some clay pits. The MANTEL brand fire brick was among the
fire brick made by this company at the Livermore plant. Rejected MANTEL and GASCO fire
bricks were found by author on the Livermore plant site.
The operation of this plant was described in a 1950 California Journal of Mines report
as follows: Buff colored fire clay from company owned deposits at Lincoln, Placer
County, was shipped in and unloaded from a siding directly into the storage sheds.
The raw clay was fed to the dry-pan grinding machines by means of a mobile hopper
and short conveyor belt. After grinding, the clay passed by bucket elevator to the
screens and then to a Bonnet single-screw auger where water was added. The mix was
extruded as three narrow ribbons of stiff mud. An automatic wire-cutting machine
simultaneously cut each ribbon into four brick units which were carried by belt
conveyor to one of two stamping machines. Here, the company name and brick type
were imprinted on each unit. The units were hand-loaded to narrow-gauge cars,
hand-trammed a short distance, and the cars were transferred to standard-gauge
cariages. The carriages were hand-trammed to the drying tunnels which were equipped
two sets of narrow-gauge tracks to accommodate the cars. There were 10 drying tunnels
in parallel, each about 70 feet in length. After drying, the bricks were loaded
into the kilns for firing. There were six round 10-burner gas-fired down-draft kilns,
about 26 feet in diameter, serviced by two rectangular stacks about 50 feet high.
Two smaller muffle kilns about 15 feet in diameter, were serviced by one 50-foot stack.
Special joints and fittings were hand-molded.

Charles Perry was the last superintendent at the
Livermore plant for Gladding, McBean & Company.
From the Livermore News, 1948
From 1946 to 1948, William Zinszer was superintendent of the Livermore plant. He
was succeeded by Charles Perry from July 1948 until the plant closed on February 28,
1949. The brick plant was razed and the abandoned property stood vacant for four
decades before the plant site was finally converted into the Brickyard Shopping Center,
anchored by the K-Mart store. Today, a small plaque on a brick monument, which displays
some of the old Livermore bricks, stands as a reminder of the former Livermore brick
plant.

Bricks of the Stockton Fire Brick Company and Gladding, McBean & Company

Face of the Stockton fire brick imprinted with the GASCO brand name.
GASCO fire brick made at the Livemore plant is dark salmon with smooth surfaces that show
crazing, small cracks, and minor blister pits. The salmon clay body appears to be a distinguishing
feature of the bricks made at this plant, compared to the yellow clay body made at the Stockton
plant and white clay body made at the Pittsburg plant. A grog of angular white quartz, up to
1/4 inch across, constitutes about 10 percent of the volume. On one
face is imprinted the brand name GASCO in recessed block letters that span a length of 3 5/8
inches and is 11/16 inch high. The name is on a rounded rectangular plate 6 1/8 inches long
and 7/8 inch high. Plate and name are centered on the face of the brick. Extruded, wire-cut,
stiff-mud, repressed process. Manufactured from 1937 to 1949 at the Livermore plant.
Length 8 1/4, width 4 1/2, height 2 1/2.

Face of the Gladding, McBean & Company fire brick imprinted with the MANTEL brand name.
MANTEL BRICK fire brick made at the Livermore plant is grayish white with a fine clay body
containing subangular white quartz grog, up to 1/8 inch across. The quartz constitutes about
10 percent of the volume. The surface is smooth with minor crazing. Edges are straight and
the corners are worn or broken. The face displays cured wire-cut grooves and pits up to 1/4 inch
across. The brand name is imprinted on one of the faces on two lines in recessed block letters.
The top line is MANTEL, which spans a length of 3 3/16 inches and is 1/2 inch high. The bottom
line is BRICK, which spans a length of 2 1/8 inches and is 1/2 inch high. Both names are on
a rounded rectangular name plate 7 1/8 inches long and 5/8 inch high. Extruded, wire-cut, stiff-
mud process. Manufactured from 1943 to 1949 at the Livermore plant by Gladding, McBean &
Company. Length 7 7/8 - 8 1/2, width 3 3/4 - 4, height 2 1/2 - 2 3/4.
