Sprigs are objects in pottery that are made in molds and attached to decorate ceramic objects. Sprigs are a type of low or bas-relief decoration. To make sprig molds, you can make impressions in clay with already made objects. In the second video that follows, the lady uses, among other things, wooden molding that can be found at most home improvement stores, as does the fourth video. You can also carve simple patterns to easily make ceramic pieces that have a uniform decoration.
Sprig molds can be made out of clay that is bisque fired (1st firing), plaster of Paris, and even silicone. After your sprig molds are ready to use, you simply make the sprigs by pressing clay into the molds. Then the sprigs can be attached to your ceramic piece by lightly scoring both the sprig and the piece, and using liquid clay, or slip to help bind the sprig and the piece together. The white decorations on Wedgwood Jasperware are sprigs, and the cameos that became encased in glass to make sulphides were made with sprig molds too. More information on Jasperware can be found on the Home page under My Favorite Clay Body.
More information on sulphides can be found on the ‘Home’ page under the blog title, ‘Combining Glass Making Skills with Ceramic Skills’ and in the menu above under ‘Glass’ or ‘Ceramics’ with the title, ‘Sulphides.’
