reburn

Reburn refers to the process of reheating a material that has already undergone a high-temperature treatment. This is often done to modify its properties or to prepare it for a subsequent step. For example, in ceramics, a bisqued piece (fired once) may be reburnt at a higher temperature to achieve full vitrification, resulting in a denser and stronger product. In metallurgy, reburning can be used to anneal or temper metals, altering their hardness, ductility, and strength. This process is distinct from a primary firing or heat treatment, as it involves a material that has already experienced at least one cycle of high heat. The specific temperature, duration, and atmosphere of the reburn are critical parameters that determine the final characteristics of the material. Understanding the reburn process is essential for controlling the quality and performance of many manufactured goods.
