Biscuit

Biscuit is porcelain without glaze, resembling marble or stone in appearance. Its surface is matte and velvety to the touch. It was especially popular in 19th-century sculpture, when it was used to create figurines, decorative panels, and portraits. Such porcelain is more difficult to clean and requires careful handling, as the unglazed surface absorbs dirt.

Interestingly, collectors sometimes jokingly call biscuit "diet porcelain" – for its lack of shine, as if they saved on it. It is the matte surface that creates a luxurious soft effect and emphasizes the details of the modeling.
