=== Construction and manufacturing ===
In the [[construction]] and manufacturing fields, it is used in lightweight [[plaster]]s, concrete and [[mortar (masonry)|mortar]], [[Thermal insulation|insulation]] and ceiling tiles.<ref name="usgs">Wallace P. Bolen [http://minerals.usgs.gov/minerals/pubs/commodity/perlite/myb1-2009-perli.pdf Perlite] USGS 2009 Minerals Yearbook</ref> It may also be used to build [[composite materials]] that are [[Sandwich structured composite|sandwich-structured]]<ref>Md Arifuzzaman and H.

Perlite filters are fairly common in filtering [[beer]] before it is bottled.{{citation needed|date=March 2021}}

Small quantities of perlite are also used in [[foundry|foundries]], [[cryogenic]] insulation, and [[ceramics (art)|ceramics]] (as a clay additive).<ref>{{cite journal |last1=Moradi |first1=L. |last2=Mirzaei |first2=M. |title=Immobilization of Lewis acidic ionic liquid on perlite nanoparticle surfaces as a highly efficient solid acid catalyst for the solvent-free synthesis of xanthene derivatives |journal=RSC Advances |date=2019 |volume=9 |issue=35 |pages=19940–19948 |doi=10.1039/c9ra03312b|pmid=35514727 |pmc=9065349 |bibcode=2019RSCAd...919940M }}</ref> It is also used by the explosives industry.<ref>[http://www.freepatentsonline.com/4940497.html Emulsion explosive composition containing expanded perlite] United States Patent 4940497</ref>
