Description & Application:
Pumice is a light weight bubbly volcanic glass - essentially a "solid foam" consisting predominantly of silica, SiO2. Deposits of pumice occur throughout the world with notable deposits on Iceland and the Italian island of Lipari.
Being a natural product pumice contains no harmful substances, it is inert with pH of around 8.0. The pebbles are resistant to frost and chemicals, and will not break down in water. They are also non-combustible and have excellent sound and thermal insulation properties.
Applications include the production of lightweight concrete, and building blocks where it is especially useful in the creation of film and theatre sets. Pumice also finds a use as a filter media for potable and industrial waste water as well as odour control.
Our clients have used pumice as pebbles in the public domain in interior and exterior landscaping where the weight of natural pebbles would not be acceptable.
Pumice absorbs colour pigments and fragrance very well and hence is useful in potpourri mixes.
