A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.
From gan′is-ter i.e a hard, close-grained siliceous stone, often forming the stratum which underlies a coal-seam

Archaeological Significance
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.
