A link to Stockton - The Stockton Fire Brick Factory

Several different kinds of branded firebricks are scattered around Harris Ranch. They include:

 An unknown "N..." branded brick.

 

 

A "DIABLO" branded brick.



 



Two different versions of "CARNEGIE" branded brick.

Both the "DIABLO" and "CARNEGIE" bricks were produced by the Stockton Fire Brick Company and each has a very interesting company biography.

"CARNEGIE" was originally manufactured by the Carnegie Brick & Pottery Factory of Carnegie, California (now a ghost town) who were in operation from 1902 to 1911. According to the linked website the many of the former employees of Carnegie Brick & Pottery went on to work for the Stockton Fire Brick Company.

"DIABLO" was originally produced by the Stockton Fire Brick Company. The company was sold to Gladding, McBean and Co (Jim Graves) in 1942. Gladdings, McBean and Co continued production of the brand for an unknown time. Through various mergers and transitions the company is still in operations today under the name of Gladdings, McBean.
