J. P. Glaser
J. P. Glaser was Julius Peter Glaser, born on November 18, 1876, in San Francisco to the parents of
Peter J. and Mary Glaser. His father Peter was a native of Germany, born in 1845, and immigrated to the
United States in 1868. He arrived in San Francisco, California, in 1872 and set up shop as a bake
oven builder. A year later, he married Mary, whose surname is unknown, and they had seven children, among
which was our subject Julius Glaser.
In 1894, Julius joined his father's oven building business as a contractor and bricklayer. It wasn't until 1898,
that Julius had earned the title of oven builder while working with his father at their shop at 1303 Stockton
Street in San Francisco. In 1901, Julius married Marie C. Rossi, and they had six children.
The Glasers had built brick ovens in the bakeries and restaurants in San Francisco and throughout the
rest of northern California over the next 60 years. The ovens were described as large and the best for
firing an even temperature. One oven that they had built in Weed, California, measured 17 feet on the side.
Some of these ovens are still operating in bakeries and restaurants.
The bricks from these ovens apparently were handmade by Julius Glaser, who imprinted his name on the
face of each brick. These were specially made bricks for the ovens that he built. Because they are square,
they may more appropriately be called refractory blocks. No description was found of how Glaser made his bricks.
It is possible that he obtained the raw fire clay from one of the brick dealers in San Francisco that sold
them. He very likely used his own furnace or kiln to fire the molded blocks. The exact years of when the marked
bricks were made are unknown, but it may have been from as early as 1906 to as late as 1940.
The 1906 earthquake and fire in San Francisco had destroyed the Glaser shop on Stockton Street. Julius Glaser
moved to 2072 Union Street in San Francisco, and that is where he probably continued to operate his
business. What became of his father Peter after 1906 is unknown as he was no longer listed with the business
nor living in San Francisco. About that time, the business was known as J. P. Glaser and Company. Exactly
when Glaser ovens ceased to be made is also unknown, though it had to be prior to 1953. Julius Glaser passed
away on April 18, 1953, in San Francisco, at the age of 76 years.
J. P. Glaser Block
The Glaser block is a white square refractory block with uneven, dull edges and dull corners. The surface
faces are flat and smooth. Some may display cracks and pits. In some of the pits can be seen subrounded
white grains of clay or altered feldspar constituting about 7 percent of the clay body. Centered across the
large face is the name "J. P. GLASER" set in recessed serif-style block letters inside a tight rectangular
outline of a name plate. The periods are square shaped. The letters are about 3/4 inch in height and span
about 7 inches in length across the face. This block was made using the soft-mud process and hand pressed
into a mold. Length 9, width 9, height 3.
