- Name: Ceramic kiln
- Manufacturer: Nabertherm
- Type: N200H
- Description of method:
A ceramic kiln is a specialized oven designed to fire ceramics and pottery at high temperatures, typically ranging from 800 °C to 1000 °C for low to medium-temperature ceramics. Its primary function is to apply controlled heat to raw clay pieces or glazed pottery to achieve a durable and hardened final product. The kiln operates by heating the interior chamber through electrical elements or gas burners, depending on the model. As the kiln heats up, the temperature inside is carefully regulated to ensure the clay or glaze undergoes the appropriate transformations. For ceramics fired at temperatures up to 1000 °C, the process generally involves two main stages: Bisque Firing: This initial firing transforms raw clay into a hard, durable body. It also removes any remaining moisture and organic impurities from the clay. Glaze Firing: In this second stage, the ceramics are coated with a glaze, and the kiln is heated to a high enough temperature to melt and fuse the glaze onto the surface, creating a smooth, glossy finish. Kilns with a maximum temperature of 1000 °C are suitable for firing low-fire ceramics like earthenware and stoneware, where the temperature allows for proper vitrification and glaze fusion without exceeding the material’s capabilities. These kilns provide precise control over temperature, ensuring consistent and high-quality results for ceramic artists and manufacturers.
