Moriage refers to the raised or beaded pattern found on pieces of porcelain or pottery. This technique was particularly popular in the 19th century and into the early 20th. The pattern was applied using “slip” – the same liquid clay from which porcelain and pottery is usually made.
Nippon pieces employ this technique quite often. In addition, moriage dragon designs are fairly common.
