A gritty yellow clay was mined on the property. The clay was elevated by a tramway from the
clay pit to the bins. A pugmill mixed and tempered the clay, which was then fed through a continuous
cutting, stiff-mud machine, with a capacity of 75,000 bricks per day. The green bricks were dried in
two large drying sheds utilizing steam for heat, with a capacity of 25,000 bricks per day. When ready,
the green bricks were fired in two 16-compartment Hoffman kilns. Two tall round chimneys provided the
draft from the kilns. The bricks were shipped on schooners at the company's wharf and by rail.
Baden red bricks were used in the first brick business building erected by Herman Gaerdes
on Grand Avenue in South San Francisco in 1898. Baden bricks were also used in the Lind Meat
Market at 221-223 Grand Avenue, as well as the brick stack at the Steiger Pottery, and the buildings
of W.P. Fuller Paint Company, all of South San Francisco, and The Ghiradelli and other buildings in
San Francisco. No bricks were produced between 1900 and 1902, when the company agreed to cease
production under the orders of the local Brick Manufacturers Trust, of which it was a member.
The Baden brick plant shut down permanently in 1906. In February 1907, the Alexander Brick and
Terra Cotta Company attempted to reopen the Baden plant, under the direction of Robert Alexander
of Alameda. The company's office was located at 58 Second St., San Francisco. Improvements were
made to the wharf and new machinery was placed. But operations halted in October 1907, when the C.W.
Raymond Company of Oakland attached the brick plant for failure to pay for the machinery supplied
by them. Evidently, no bricks were produced by the Alexander Brick and Terra Cotta Company. The plant
was razed shortly after the property was disposed of in 1919.

Red repressed brick has a compact, smooth surface of a stiff-mud extrusive process.
The color is uniform and may display tiny white and black clasts, rounded and
up to 1/4 inch across, and rare shell fragments. The clay body is also full of
quartz sand and a round black mineral (magnetite?). Both faces display curved
wire-cut marks on a pitted surface. The edges may have repressed markings. The
sides and ends may have transverse extrusion grooves and stack indentions.
Length 8, width 4, height 2 3/8.
