This tutorial broken ceramic bowl was put together as an example showing how Lakeside Pottery generally fills in missing pieces using clay and fired ceramic. Terra Cotta and softer ceramic missing pieces are fired to cone 06 (1828 degree F) and porcelain, stoneware and harder clays are fired to … cone 6 (2230 degree F). This method and process is the most complete and reliable way to brings a broken ceramic item with missing pieces closest to it's original states. It is also more difficult to detect the repair visually, with black light or sonar material loop detector.

In this example, this antique bowl broke to several pieces but the base of the bowl was chattered to tiny little pieces and powder, thus, requiring large sections to be filled in.
