Scottish Whin stone
Whinstone is a provincial name used in the quarrying industry to describe any hard dark-coloured rock. Examples include the igneous rocks basalt and dolerite. The material supplied by BBS is quarried throughout central Scotland and is a classified as a quartz dolerite. It can be supplied in a range of colours from dark grey through to a dark green and may occasionally contain a reddish variation. This material has been used extensively throughout Scotland over hundreds of years for kerbs and setts and is today used on exclusive projects where stone heritage is a key factor, such as Rosslyn Chapel and St. Andrews Cathedral, Glasgow.
