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.
Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster

Formation
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.

Ganister vs Anthracite 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 Anthracite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Ganister and Properties of Anthracite. Learn more about Ganister vs Anthracite in the next section. The interior uses of Ganister include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Anthracite include Not yet used. Due to some exceptional properties of Ganister and Anthracite, 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 Anthracite include Cement manufacture, For road aggregate, Making natural cement, Steel production.
More about Ganister and Anthracite
Here you can know more about Ganister and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Ganister and Anthracite consists of mineral content and compound content. The mineral content of Ganister includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Anthracite includes Calcite, Clay, Clay Minerals. You can also check out the list of all Sedimentary Rocks. When we have to compare Ganister vs Anthracite, the texture, color and appearance plays an important role in determining the type of rock. Ganister is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Ganister is Rough and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Ganister vs Anthracite. The hardness of Ganister is 6-7 and that of Anthracite is 1-1.5. The types of Ganister are Not Available whereas types of Anthracite are Semi-anthracite and Meta-anthracite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Ganister is white while that of Anthracite is black. The specific heat capacity of Ganister is 0.92 kJ/Kg K and that of Anthracite is 1.32 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 Anthracite is heat resistant, water resistant.
