Witherite

(BaCO3)
The carbonate ore of Barium (BA). It is only found in a few locations worldwide and is named after the Dr. Withering who discovered it. The major worldwide source of Witherite is in the Fallowfield and Settlingstones area of Northumberland - though a further small amount has been found in County Durham. The Settlingstones Mine was the world's major producer of this mineral - used in preference over Barytes (BaSO4) to produce Barium (Ba). It was used in (experimental?) pottery glazes by Josiah Wedgewood.
