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.
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

Formation
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

Ganister vs Limestone 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 Limestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Ganister and Properties of Limestone. Learn more about Ganister vs Limestone in the next section. The interior uses of Ganister include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Limestone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Ganister and Limestone, 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 Limestone include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium.
More about Ganister and Limestone
Here you can know more about Ganister and Limestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Ganister and Limestone consists of mineral content and compound content. The mineral content of Ganister includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Sedimentary Rocks. When we have to compare Ganister vs Limestone, 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, Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. Appearance of Ganister is Rough and that of Limestone is Rough and Banded. Properties of rock is another aspect for Ganister vs Limestone. The hardness of Ganister is 6-7 and that of Limestone is 3-4. The types of Ganister are Siliceous rock whereas types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Ganister and Limestone is white. The specific heat capacity of Ganister is 0.92 kJ/Kg K and that of Limestone is 0.91 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 Limestone is pressure resistant.
