Schieferspalterei — Mosel-Rhein-Schieferbergbau
The hand-splitting of Rhenish slate (Mayen-Kottenheimer Schiefer or Moselle slate) into roofing tiles — a tradition central to the visual character of the Rhine and Mosel valley historic townscapes, whose steep-roofed slate-tiled historic buildings define the regional architectural identity. The Schieferspalter reads the correct split plane through a combined visual-and-acoustic assessment of the stone before splitting, identifying the cleavage plane that will produce the correct thin, flat roofing tile rather than an angled split that produces a wedge-shaped piece unsuitable for roofing.
