The production of ceramic vessels requires detailed knowledge of the physical properties of different clays and tempering materials, as well as knowledge about how these combine and react under specific firing conditions. Potters knew where to find and identify quality clays sources and understood what materials to add to the clay to prevent it from cracking during drying. They recognized the limits of the tempered clay’s strength during shaping and after firing. Potters also employed a range of techniques and methods in decorating their containers; some of these decorations transmitted important symbolic information as well. Without kilns, special skills were required in using open fires to produce pots. When ceramic-making arrived in Canada, it was adapted to take into account local needs and raw materials.
