Anotations

Scope note:

A siliceous sandstone from Derbyshire, England; it is also considered a gritstone, specifically a Darley Dale gritstone. It is even-grained and exceedingly hard, making it an excellent choice for ashlar and paving work. Its silica content is so high, however, that trade unions have been known to ban its use owing to the danger of silicosis; whenever possible, Stancliffe sandstone is now only worked by wet methods.
