Web26 nov. 2024 · What is Perlite Made of? Volcanic rock or glass make up the majority of perlite. It develops when naturally occurring minerals solidify and entrap water in them as they cool after being molten lava. Perlite is a kind of rock or glass when found in its natural form. The raw volcanic rock or glass is heated to produce white lightweight perlite. WebPearliteis generally observed to nucleate at austenite grain boundaries and grow into the parent phase as approximately spherically shaped grains. These grains are called nodules and are composed of a number of structural units called colonies in which all of the plates are parallel.
