The Society is grateful for the continuing support of Imerys Minerals Ltd in providing accommodation for the archive and in allowing the Society to take custody of artefacts, documents and other material, which is surplus to Imerys’ requirements.



These range from leases or “Setts” to work for china clay, granted to the early china clay companies in the 19th century, to engineering drawings, plans, correspondence and publications from E.C.L.P., ECC and the many other clay companies. They have mostly been catalogued and it is possible to search for information on particular locations or topics.

We have a large collection of Ordnance Survey maps, e.g. 1907 series 1:2500 sheets covering most of Mid Cornwall and North Cornwall and some sheets from West Cornwall and Devon; 1973 series 1:2500 covering most of Mid Cornwall and some of West Cornwall and Devon; and 1906 series 1:10560 covering most of Mid Cornwall and some of Devon.

We also have aerial photographs of the China Clay area dating from 1948.
