A hand-poured glaze, black and iridescent, that stands out against the matt white bisque porcelain: this is the distinguishing feature of the "Obsidian" collection. Named after the unfathomable, deep black volcanic glass, each fragment of which shimmers in its own unique way, every single object in the collection by Stefanie Hering is likewise unique. The sophisticated glaze settles differently on each piece, creating new effects and colour facets every time, from almost translucent grey to impenetrable black.
