Silica has an important use in the form of silica brick or "ganister" for lining furnaces and converters in which acid slags are formed.

The use of manganese as standard practice at this time is not referred to,[70] but the rotary converter and the use of ganister linings are mentioned for the first time.

The suitability of a fireclay for the manufacture of the various fireclay goods depends upon its physical character as well as upon its refractoriness, and it is often necessary to mix with the clay a certain proportion of ground firebrick, ganister, sand or some similar refractory material in order to obtain a suitable brick.

Among such substances are fireclay and firebricks, certain sandstones, silica in the form of ganister, and Dinas stone and bricks, ferric oxide and alumina, carbon (as coke and graphite), magnesia, lime and chromium oxide--their relative importance being indicated by their order, the last two or three indeed being only of limited use.

Silica is used in furnace-building in the forms of sand, ganister, a finely ground sandstone from the Coal Measures of Yorkshire, and the analogous substance known as Dinas clay, which is really nearly pure silica, containing at most about 2½% of bases.
