Chamotte

Chamotte

Chamotte is a type of ceramic raw material composed of clay that has been fired and then ground into a fine powder or granules. It is often used as a non-plastic additive in clay bodies to improve their thermal shock resistance, reduce shrinkage, and enhance the texture and appearance of the finished ceramic piece. The inclusion of chamotte in a clay body also helps to minimize warping and cracking during the drying and firing processes. The particle size of chamotte can vary depending on the desired properties of the final product, with coarser grains providing more texture and finer grains contributing to a smoother surface. Chamotte is commonly used in the production of refractory bricks, pottery, sculpture, and other ceramic applications where improved stability and durability are required. The proportion of chamotte in a clay body can range from a small percentage to a significant portion, depending on the specific requirements of the project. The use of chamotte dates back to ancient times, with evidence of its inclusion in ceramic materials found in various archaeological sites around the world
