Home · Dicalite / Dicaperl Minerals
Perlite is one of nature's most versatile and efficient minerals. It is formed by molten rock—volcanic glass—processes that trap water into the perlite matrix over geologic time periods.
What is Perlite? Definition from MaximumYield
Perlite, recognizable as those small white bits present in your potting soil, is an amorphous volcanic glass that is used in commercial and horticulture practices. This mineral is different from other volcanic minerals as it can expand up to 13 times its original size when heated, resulting in a lightweight material.
