Pumice is a result of a volcanic glass explosion. It is high in silica and low in iron and magnesium content. It is light in colour, rocky foam and floats on water due to so much air in its structure, but will sink as it becomes saturated. Pumice is used in construction materials and in…
Scoria is a highly vesicular, dark coloured volcanic rock. Scoria is a volcanic rock that found along the seashore. The density of Scoria is low due to its many macroscopic ellipsoidal vesicles, but it sinks in water. Scoria is used in purposes of high-temperature insulation, water drainage, road building and landscaping. (OUT OF STOCK)
Clay is extensively pretreated and then heated and expanded in a rotary kiln. Then, the product is sintered at about 1100-1200 °C to produce expanded clay. Expanded clay is strong, thermal insulation, fire resistance and sound absorbent due to its high void content. Expanded clay is used in construction, geotechnical, landscaping, green roof, gardening, roof…
Perlite is a form of volcanic glass that is mined all over the world. Natural perlite dark black or grey coloured amorphous glass. Perlite is a formless volcanic glass that has moderately high water content. Horticultural perlite is made by exposing perlite to heat, which causes the trace water contained in the perlite to expand,…
