Kiln furniture are refractory elements, usually shelves or disks, which are placed between the ceramic pieces stacked in the kiln during firing. Their main function is to prevent the pieces from touching and sticking together as the glazes melt, ensuring that each object maintains its individual shape and finish. This furniture allow the hot air to circulate evenly around the pieces, promoting a homogeneous firing and preventing deformations or defects caused by direct contact between the pieces.
There are different types of kiln furniture depending on the type of kiln and the specific firing requirements. Some are made of insulating materials that help maintain a constant temperature at each kiln level, while others can be of various shapes and sizes to adapt to different types and sizes of parts.
In addition to preventing sticking, kiln furniture contributes to kiln energy efficiency by improving heat circulation and reducing thermal losses. Their correct use can extend the service life of kiln shelves, preventing them from being damaged by direct contact with hot glazeed parts.
Interesting Fact
In the industrial production of ceramic tableware, the implementation of automated separation systems has made it possible to significantly increase the speed and efficiency of firings. These systems use mobile or adjustable kiln furniture that automatically adapt to the type and size of the pieces, reducing preparation time and increasing consistency in the quality of the final products.
Helpful Tip
Keep the kiln furniture clean to prevent glaze or clay residue from adhering to them and subsequently transferring to the pieces in future firings. Regularly inspect the kiln furniture for wear or damage and replace them when necessary to maintain their effectiveness.
