Welsh Slate is a type of metamorphic rock primarily found in Wales. It is formed from shale that has undergone intense heat and pressure, resulting in a dense, durable material. Known for its distinctive blue-grey color, Welsh slate is often used in roofing, flooring, and various architectural applications due to its weather resistance and aesthetic appeal. The extraction of Welsh slate has a long history, particularly in regions like Snowdonia. The slate industry played a significant role in the local economy during the 19th century, with many quarries operating to meet the high demand for this versatile stone. Today, Welsh slate remains a popular choice for construction and design projects.
