Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.

Scoria vs Sandstone 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. Scoria vs Sandstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Scoria and Properties of Sandstone. Learn more about Scoria vs Sandstone in the next section. The interior uses of Scoria include Decorative aggregates and Interior decoration whereas the interior uses of Sandstone include Countertops, Decorative aggregates and Interior decoration. Due to some exceptional properties of Scoria and Sandstone, they have various applications in construction industry. The uses of Scoria in construction industry include Cement manufacture, Construction aggregate, For road aggregate, In landscaping and drainage works and that of Sandstone include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.
More about Scoria and Sandstone
Here you can know more about Scoria and Sandstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Scoria and Sandstone consists of mineral content and compound content. The mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica and mineral content of Sandstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Scoria vs Sandstone, the texture, color and appearance plays an important role in determining the type of rock. Scoria is available in black, brown, dark grey to black, red colors whereas, Sandstone is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Scoria is Glassy and Vesicular and that of Sandstone is Rough. Properties of rock is another aspect for Scoria vs Sandstone. The hardness of Scoria is 5-6 and that of Sandstone is 6-7. The types of Scoria are Basaltic Scoria and Andesitic Scoria whereas types of Sandstone are Grey Sandstones, Crystallized Sandstones, Hard Sandstones , Carbonate Cemented Sandstones and Ganister. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Scoria and Sandstone is white. The specific heat capacity of Scoria is 0.84 kJ/Kg K and that of Sandstone 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.Scoria is heat resistant, impact resistant, pressure resistant, wear resistant whereas Sandstone is heat resistant, impact resistant, pressure resistant.
