It is found as strontium sulfate ([[Strontium|Sr]][[Sulfur|S]][[Oxygen|O]]<sub>4</sub>), which is commonly used in [[fireworks]] and in some metal [[alloy]]s. Often occuring in crystallized formation, celestine derives its name from the [[Latin]] word for [[celestial]], ''caelestis''.<ref>{{cite dictionary|title=Celestine|dictionary=Collins English Dictionary|via=collinsdictionary.com|url=https://www.collinsdictionary.com/dictionary/english/celestine}}</ref> == References == {{Reflist}} [[Category:Ores]] [[Category:Minerals]] {{sci-stub}}
