A bstract The staining of silica brick was found to occur in a critical temperature range of 900°‘ to 1000°C. Concurrently the brick had to be “soaked“ in this temperature range and exposed to an oxidizing atmosphere. Stained brick could be “cleaned up” or staining prevented by manipulation of the foregoing set of conditions as well as by additions of 4.5% or more of lime. The experimental data examined in the light of the system CaO‐Fe 2 O 3 ‐SiO 2 suggest that the colorant is the mineral dicalcium ferrite.
