Sintering is an important step in ceramic manufacturing, involving the transformation of compacted ceramic powders, known as the green body, into solid and durable structures. Through controlled heating below the material’s melting point, particles bond together, resulting in densification and the formation of a cohesive ceramic mass. This process, which may also include grain growth, is instrumental in producing a variety of ceramic products, from tiles to advanced components for electronics and industry. The specific sintering conditions are tailored to the type of ceramic material and the desired properties of the final product, showcasing the versatility of this technique in creating robust and functional ceramic structures.

In the context of pizza ovens, firebrick cooking tiles and Biscotto stones do undergo sintering when they are fired in a high-temperature kiln, while pizza oven domes, made using air-dry refractory castable, do not.
