Welsh Slate for house signs

Slate is stone created from the very fine mud and sediment of prehistoric swamplands laid down over millions of years. This ancient history defines the very nature of Slate.
Fine layers of silt laid down over millions of years – layer after layer, compress and harden and to form a stone that can be very hard and tough.

Most types of slate are resistant to weathering and untypically for a natural stone, high in tensile strength. This allows us to make and supply longer and narrower house name plaques than is possible in sandstone etc.
The high tensile strength of slate is due to the layered or laminated nature of the stone, this can best be seen by the application of Slate as roofing tiles. Slates can be along split down very thin to form a strong light weight roofing covering that has been used for thousands of years and indeed is still widely used to day.
