5. • Pumice is used more extensively as a building
material outside the United States,
whichexplained the large global production of
pumice relative to that of the United States.
• In Europe, basic home construction uses
significantly less gypsum wallboard because
stone and concrete are the preferred building
materials. Prefabricated lightweight concrete
walls, which may contain pumice as lightweight
aggregate, are often produced and shipped to
construction locations.
• Because of their light weight, strength, and
cementitious properties, pumice and pumicite
perform well in European-style construction. In
2017,
• Turkey was the leading exporter of pumice to
Asia and Europe.

10. Superior Quality Pumice
An industrial materials company can be very good at what they do—competitive pricing,
logistical expertise, consistency on spec, innovative and efficient production methods—
but without a quality product, the high ground simply can’t be held. And while we pride
ourselves on all of the above...we also count ourselves fortunate that our pumice
deposit is world-class.
Over 70-percent of our processed pumice is exported into countries and regions that
often have domestic pumice sources nearby—because our customers require a
superior quality pumice product.
Worldwide, our pumice enjoys advantages in whiteness (GE brightness of 84), hardness
(Mohs’ scale 6), density (specific gravity of 2.35 g/cc) and natural purity. Our deposit
has a confirmed yield in the millions of tons. Three modern processing facilities and a
state-of-the-art testing lab ensure we can consistently deliver to the ordered
specification.
