Caption: Rock specimen of sandstone from Corsehill Quarry, Annan, Dumfries & Galloway Region, Scotland.
Description: Fine-grained reddish-brown sandstone with uniform texture. The strong red colour is caused by very fine-grained iron oxides which coat the individual quartz sand grains.

This specimen is from the National Portrait Gallery in Queen Street Edinburgh (1885-90), and was obtained during repairs in the 1980s. An advert for Corsehill quarries in 1902 states that the stone is used extensively throughout England, Ireland and Scotland, and has been exported to the United States, Canada, Sweden and Denmark.
