Porto Slate is a muscovite-sericite-schist, which is mined in the north east of the provincial city of Portugal Valongo. It was formed about 400 million years ago in the age of the Ordovician. Today he is one because of its robust surface and its massive blue-gray to deep black hue to the top slate week.
