Sitter

Sitter

The sitter is a mechanical device used in kilns to automatically shut down the kiln when the desired temperature is reached. It works by means of a support that holds a pyrometric cone or a pyrometric rod, which deforms and releases a mechanism that interrupts the kiln's power supply. This system is widely used in electric kilns, especially in small or medium-sized workshops, as it allows precise firing without the need for constant supervision. The sitter is especially useful for beginners, as it eliminates much of the uncertainty associated with temperature control. However, it requires regular maintenance and proper calibration to ensure optimal performance. Despite being a relatively simple technology, it has revolutionized modern ceramics by enabling safer and more reliable firings.

Interesting Fact

The sitter was introduced to ceramics in the 20th century as a practical solution to avoid overfiring and improve the energy efficiency of electric kilns. Prior to its invention, ceramists had to manually monitor the kiln temperature for hours at a time.

Helpful Tip

Make sure that the pyrometric cones used are compatible with the firing temperature you wish to achieve. Regularly inspect the sitter mechanism to verify that it is clean and functioning properly. Consider combining the sitter with an external timer as an additional safety measure.
