Bideford Black - a unique, naturally occurring rare pigment only found in Bideford, North Devon (UK). The deposits were formed millions of years ago and were compressed by tectonic plates; the compression helped form the mineral that has a rich black color. It was first discovered in the 17th century and mined for making black ink. It became less popular in the 20th century when many new synthetic inks became available.
