Product Details
This naturally beautiful British slate has outstanding technical characteristics and was formed during the Ordovician period some 450 million years ago in the North West peninsular of Wales.
Adorning the roofs, floors and walls of iconic and heritage projects throughout the UK and the world, Welsh Slate brings a wealth of knowledge and experience within the stone industry.
The Cwt-y-Bugail riven slate is a dark blue slate, which is quarried at the Cwt-y-Bugail quarry, close to Blaenau Ffestiniog in North Wales. This quarry has been operated since the mid 19th Century and is the highest operating industrial site in the UK. During World War II, many of Britain's most valuable paintings and national treasures were stored deep inside the slate caverns for safe keeping!
