Broughton Moor slate is a metamorphic volcanic ash from the Borrowdale Volcanic Group formed during the Ordovician period and is between 450-500 million years old. Broughton Moor is a mid green stone, often highlighted by contrasting white veins and beautiful tone changes that reflect its natural origins. It can be extracted in a variety of green tones to add a dark and light green contrast to surfaces, yet purvey the beauty of its natural markings, and has been used for generations to provide cladding, walling, cills, lintols, copings, flooring, stairs and worktops. The richness of Broughton Moor makes it ideal for use in interior furniture and fittings, whether in traditional or modern design schemes.
