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.
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

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.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

Ganister vs Quartzite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Ganister vs Quartzite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Ganister and Properties of Quartzite. Learn more about Ganister vs Quartzite in the next section. The interior uses of Ganister include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Ganister and Quartzite, they have various applications in construction industry. The uses of Ganister in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar and that of Quartzite include Arrowheads, As dimension stone, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone.
More about Ganister and Quartzite
Here you can know more about Ganister and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Ganister and Quartzite consists of mineral content and compound content. The mineral content of Ganister includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Ganister vs Quartzite, the texture, color and appearance plays an important role in determining the type of rock. Ganister is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Ganister is Rough and that of Quartzite is Lustrous. Properties of rock is another aspect for Ganister vs Quartzite. Hardness of Ganister and Quartzite is 6-7. The types of Ganister are Siliceous rock whereas types of Quartzite are Orthoquartzite and Metaquartzite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Ganister and Quartzite is white. The specific heat capacity of Ganister is 0.92 kJ/Kg K and that of Quartzite is 0.75 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Ganister is heat resistant, impact resistant, pressure resistant whereas Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
