Nero Bernino

Nero Bernino is a natural grey-green slate from the Bernina Pass in the canton of Graubünden (Grisons) in eastern Switzerland. Chemically, it belongs to the group of hydrated aluminium silicates. When grinded, the relatively bright, crystalline slate makes a beautiful, medium grey stone powder. Due to the containing glimmer particles, it has a great shimmer, and is intense in color. As pigments, slate black and slate grey are not well-known among artists, although the greyish-green slate powder from the Swiss Alps is suitable for all techniques: The pigment can be used in acrylics, oil, tempera, watercolor/gouache, fresco/ lime, ceramic, silicate binder, waterglas, and cement/tadelakt.
