What is a biscuit in the context of ceramics?

In the context of ceramics, a biscuit refers to unglazed porcelain that has been fired once but has not yet been coated with glaze. This stage in the ceramics process is critical, as the biscuit ware is porous and provides a surface for subsequent glazing. The term "biscuit" highlights the transition between raw clay and the final glazed product, showcasing the distinct characteristics of the material that is ready for the next steps in the ceramic process.

Understanding the term is important in ceramics, as it emphasizes not just the material's physical properties but also its theoretical implications in design, strength, and the ability to accept glazes during further processing.
