Typical Minerals
Volcanic Glass. Pumice has cooled too quickly for minerals to form. Chemical composition, however, will be from the bottom of Bowen's Reaction series (i.e. felsic).
Detail Description
     Pumice is a vesicular, foamy, very light weight, light colored rock formed by abundant, rapid gas escape during formation. It is often a pyroclastic product.
