Great Tew Ironstone

Great Tew ironstone (a ferruginous limestone) has been extracted from The Great Tew Quarry in Chipping Norton, Oxfordshire since the early 17th Century - and is now the only active ironstone quarry in the UK. This very distinctive stone is medium to course grained with its colour varying from orange/brown, dark brown to white with some fine grained mineral veins.

Mainly used for traditional house building from the South of Oxford to the North of Lincolnshire, as well as restoration projects where conservation grade ironstone is required.
