Sprigging or sprigged decoration is a technique for decorating pottery with low relief shapes made separately from the main body and applied to it before firing. Usually thin press moulded shapes are applied to greenware or bisque. The resulting pottery is termed sprigged ware, and the added piece is a "sprig". The technique may also be described by terms such as "applied relief decoration", especially in non-European pottery.

Pâte-sur-pâte is a French term meaning "paste on paste". It is a method of porcelain decoration in which a relief design is created on an unfired, unglazed body, usually with a coloured body, by applying successive layers of (usually) white porcelain slip with a brush. Once the main shape is built up, it is carved away to give fine detail, before the piece is fired. The work is very painstaking and may take weeks of adding extra layers and allowing them to harden before the next is applied.
