A ceramics museum is a museum wholly or largely devoted to ceramics, normally ceramic art, whose collections may include glass and enamel as well, but will usually concentrate on pottery, including porcelain. Most national collections are in a more general museum covering all the arts, or just the decorative arts, but there are a number of specialized ceramics museums, some concentrating on the production of just one country, region or manufacturer. Others have international collections, which may concentrate on ceramics from Europe or East Asia, or have global coverage.
