Mirabilite is unstable and quickly dehydrates when exposed to dry air, turning into the powder thenardite.  It owes its name to Johann Rudolph Glauber who dubbed it “sal mirabile” (“wonderful salt”) when he inadvertently synthesized it while working with sulfuric acid and salt. It is also known as Glauber’s salt.</skos:scopeNote><skos:inScheme rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en"/><skos:related rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31373651"/><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=14072388"> <skos:prefLabel xml:lang="es">mirabilite (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=9838443"> <skos:prefLabel xml:lang="ca">mirabilite (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch>  <dct:created>2026-03-30 20:32:58</dct:created>  </skos:Concept></rdf:RDF>
