I go by ActualJoe, an actual average Joe working on reverting nonconstructive edits. I would consider myself pretty open to opinions and mistakes, and I will take most things lightly, although I will do my job and try and keep vandalism from happening on Wikipedia.
Celestine is a mineral consisting of strontium sulfate (SrSO4). It is named for its occasional delicate blue color. Celestine and the carbonate mineral strontianite are the principal sources of the element strontium, commonly used in fireworks and in various metal alloys. The mineral occurs as crystals, and also in compact massive, and fibrous forms. It is found worldwide, mostly found in sedimentary rocks, usually in small quantities. Pale blue crystal specimens, as shown in this photograph, are found in Madagascar.
