Specialty chemicals produced by its subsidiaries are alkyl benzene sulfonate, azodicarbon amide, methylene stabilizer, dyestuff, poly aluminum chloride, silica flour
, textile auxiliaries, etc.
Clay occurs throughout the matrix, where it is admixed with silica flour
, and as thin (a few millimetres to 60 cm), horizontal to sub-horizontal, lenticular, poorly stratified horizons interbedded with the silica sand.

They are frequently covered with a protective wash, silica flour
or other refractory material.
Other approaches to improve shell removal characteristics include using mixtures of alumino-silicate and fused silica for the backup stucco with fused silica flour
for the slurry; and using one or two intermediate dips of fused silica slurry/fused silica stucco and alumino-silicate sluny/alumino-silicate stucco for the backup dips.
are built with a different material than the one used in the mold, such as clay brick, sand with high-proportion silica flour
or cement-bonded alumina for higher resistance to erosion.
For example, if the shell material is made of mostly fused silica flour
, a large fraction of the flour and the binder can be made to crystallize.
