Definition
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.
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel

Features
Available in Lots of Colors and Patterns, Generally rough to touch, Very fine grained rock
Clasts are smooth to touch, Easily splits into thin plates, Has High structural resistance against erosion and climate
Archaeological Significance
Formation
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.

All about Ganister and Flint Properties
Know all about Ganister and Flint properties here. All properties of rocks are important as they define the type of rock and its application. Ganister and Flint belong to Sedimentary Rocks.Texture of Ganister is Clastic, Granular, Rough whereas that of Flint is Banded, Rough. Ganister appears Rough and Flint appears Glassy or Pearly. The luster of Ganister is dull while that of Flint is vitreous. Ganister and Flint are available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. The commercial uses of Ganister are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones and that of Flint are creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms.
