Definition
Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt
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.

Formation
Tachylite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.

Tachylite vs Ganister 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. Tachylite vs Ganister characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Tachylite and Properties of Ganister. Learn more about Tachylite vs Ganister in the next section. The interior uses of Tachylite include Decorative aggregates and Interior decoration whereas the interior uses of Ganister include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Tachylite and Ganister, they have various applications in construction industry. The uses of Tachylite in construction industry include Cutting tool, Knives, Landscaping, Scrapers and that of Ganister include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.
More about Tachylite and Ganister
Here you can know more about Tachylite and Ganister. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tachylite and Ganister consists of mineral content and compound content. The mineral content of Tachylite includes Feldspar, Olivine and mineral content of Ganister includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Tachylite vs Ganister, the texture, color and appearance plays an important role in determining the type of rock. Tachylite is available in black, dark brown colors whereas, Ganister is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Tachylite is Glassy and that of Ganister is Rough. Properties of rock is another aspect for Tachylite vs Ganister. The hardness of Tachylite is 5.5 and that of Ganister is 6-7. The types of Tachylite are Not Available whereas types of Ganister are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Tachylite is vermilion while that of Ganister is white. The specific heat capacity of Tachylite is 0.56 kJ/Kg K and that of Ganister is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Tachylite is heat resistant, impact resistant, wear resistant whereas Ganister is heat resistant, impact resistant, pressure resistant.
