Ty Powdwr/Magazine at Cwt-y-Bugail Quarry Ty Powdwr was where the Powdwr Du (lit. "black powder" i.e. gunpowder) was stored. Gunpowder was used in the slate quarrying industry rather than dynamite or gelignite as the former gave a 'gentler' explosion which could dislodge blocks of rock, some weighing tens of tons, without shattering them.
