Image 1:Piece of #WALDENSTEIN ore from Carinthia. Image 2: underground in the mine, the shiny Grey are the ore seams.
The ore is composed of dark Grey bladed hematite ( #specularite in English/ #Eisenglimmer auf Deutsch) and also contains pyrite (the yellow mineral in image 1). This ore is actually used as an industrial mineral and is the basis for rustproof paints, esp those used to on iron bridges. Can't rust that which is already rust😎
