Slate and its UK Locations
The slate industry is worldwide, with 90% of Europe’s natural slate used for roofing originating in Spain. The US also possesses important producing regions, with the state of New York being home to The Slate Valley area, being one of the places in the world where coloured slate (which is not grey or blue) is obtained.
Today, however, we’re putting the spotlight on the slate industry closer to home, here in the UK. Major slate mining regions exist in areas of the UK. Let’s take a closer look at these quarries and what kinds of slate are mined here.
North Wales – Penrhyn Quarry
The Welsh slate industry has an extensive history. It began in the Roman period, when slate was used to roof the fort at Segontium, now Caernarfon. The first large-scale slate mining in North Wales began with the opening of Penrhyn Quarry in 1782 (back then known as Cae Braich y Cafn quarry). However, the first reference to slate extraction from Penrhyn is from back in 1570, when it was mentioned in a Welsh poem.
In the 19th century, along with Dinorwic Quarry, Penrhyn Quarry dominated the Welsh slate industry. They were the world’s largest quarries. The main pit of Penrhyn Quarry is nearly one mile long and 370 metres deep, it was worked by nearly 3,000 quarrymen. It still remains Britain’s largest slate quarry today, but its workforce is now nearer 200, and was superseded in size by slate quarries in China, Spain and the US.
At UK Slate, we stock slate from Penrhyn Quarry, including:
Welsh Heather Blue – This beautiful slate comes in heather blue or purple, and its striking colour is incredibly rare in the industry.
North Wales – Cwt-y-Bugail Quarry
Cwt y Bugail Quarry is located above Ffestiniog in North Wales. It first worked as a trial pit around 1840 and produces dark blue grey slate. Today it is an open cast quarry, whereas slate was originally mined in deep caverns and pillars. In fact, during World War II the quarry was used to store art treasures from the National Gallery and the Tate Gallery for safe keeping.
At UK Slate, we stock this stunning dark blue grey slate:
Welsh Dark Blue Grey – This slate is used by architects worldwide, it is renowned for its stunning looks, reliability and ease to work with and is regarded as one of the finest slates in the world.
Cumbria – Kirkby, Broughton Moor, Elterwater, Tilberthwaite Valley and Honister Slate Mine
Parts of Cumbria have significant history with the slate industry, dating back 400 years. The industry exploded in the 18th and 19th century in response to the demand for slate roofing as a result of the industrial revolution, and the growth of towns in Northern England.
Today the slate industry in Cumbria is just a fraction of what it was, but it is still active at Kirkby, Broughton Moor, Elterwater, Tilberthwaite Valley and Honister Slate Mine.
At UK Slate, we stock slate mined in Cumbria, including:
Westmorland Green – Quarried for over 400 years, this slate provides an exquisite finish to a home. It is quintessentially British with its distinctive green colour which is created from the metamorphosed volcanic ash of the Borrowdale Volcanic group of mountains in the heart of the Lake District.
