Application: Praseodymium Oxide, also called Praseodymia, used to colour glasses and enamels; when mixed with
certain other materials, praseodymium produces an intense clean yellow colour in glass. Component of didymium
glass which is a colourant for welder's goggles, also as important additive of Praseodymium yellow pigments
