WELSH SLATE: (Pictured- Welsh slate Wine rack)
Welsh slate is proven to be the toughest natural slate product known to man. It has the longest lifecycle when compared to any other slate and is available in a wide variety of colours.
All of this slate was formed during the Palaeozoic Era, at a time, when what we today know as north Wales was buried beneath the sea.
It was during the Cambrian period that mud, pebbles and sand collected at a depth of 1,525 m. in the Caernarfon area.
During the Ordovician period, volcanoes erupted on the seabed & over time, sediment buried what we now call slate to a depth of around 7,600 m.
Violent disturbances during the Silurian and Devonian periods pressed the already formed rocks together.
Both these sedimentary and volcanic rocks were folded by this pressure into mountains and formed part of a chain running approximately from the north-east to the south-west.
Welsh slate has many uses and I have included some of my favourites in our latest photo album.
Enjoy!
