Celestite is found in sedimentary stone usually in conjunction with halite and dolomitic limestone. Specimens have been found in England (Bristol), Italy (Sicily), Mexico (Matehuala) and the U.S. (Ohio, California). Celestite is mined as a source of strontium. It is also used in the manufacture of ceramics, glass, and fireworks.</skos:scopeNote><skos:inScheme rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en"/><skos:broader rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31320469"/><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_es/index.php?tema=14072413"> <skos:prefLabel xml:lang="es">celestite (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_ca/index.php?tema=9838467"> <skos:prefLabel xml:lang="ca">celestite (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch>  <dct:created>2026-03-30 20:32:58</dct:created>  </skos:Concept></rdf:RDF>
