A ceramics museum is a museum wholly or largely devoted to ceramics, usually ceramic art. Its collections may also include glass and enamel, but typically concentrate on pottery, including porcelain. Most national collections are in a more general museum covering all of the arts, or just the decorative arts. However, there are a number of specialized ceramics museums, with some focusing on the ceramics of just one country, region or manufacturer. Others have international collections, which may be centered on ceramics from Europe or East Asia or have a more global emphasis.
