Harbison-Walker History First founded in 1865 as the Star Fire Brick Company, Harbison-Walker has been producing world class refractories for over 140 years. Harbison-Walker has been supplying refractory products to the oil refining industry since the 1940's and in 1998 it acquired A.P. Green Industries who, at the time, was one of the largest suppliers of refractory to the oil refining industry in the world.
