mineraloftheday: Mineral Of The Day #141: Scolecite Mohs Hardness Scale: 5-5.5Category: tectosilicate mineral, zeolite groupFormula: CaAl2Si3O10.3H2O Fun Facts: Scolecite is a common zeolite that occurs with other zeolites in the amygdaloidal cavities (cavities filled with secondary minerals). It is pyroelectric, meaning it generates a temporary voltage when heated or cooled. It is used as a chemical filter, and as mineral specimens. It is named after the Greek word skolec meaning “worm,” referring to its propensity to curl when heated.
