A mosaic of slate

This slate from Canada, a Quebec discovery at the Pavillon des nouveautés, is like a puzzle. Cut by a computer controlled water jet cutter, in the plant of L'Ardoisière, Prévost, it reproduces a pattern of 18 different tiles, and sells with spacers and a precise plan. It costs $ 16.95 per square foot for a Terra-Nova uncalibrated stone covering (about 3/8 inch thick), and $ 22.95 for another calibrated stone (exactly 5/8 inch). thickness). Canadian slate, very dense and non-porous, does not crumble over time, unlike Chinese slate.
