Glendyne slate is produced in the town of Saint Marc du Lac Long, Quebec, Canada. This blue/grey slate is available exclusively from Cembrit Blunn Ltd. Glendyne slate has a fast growing reputation for quality due to the exceptional slate deposit and the combination of modern extraction technology with traditional finishing skills. Produced from deposits laid down in the Ordovician era some 500 million years ago this quarry was first opened by British slate quarrymen in the early part of the 20th century.
