What is the difference between Spode fine earthenware and Spode bone china?

Fine earthenware is a clay-based ceramic fired and glazed for table use, it is usually opaque, slightly heavier, and well suited to transfer-printed decoration. Spode’s modern Blue Italian line is sold as fine earthenware, which matches the brand’s deep history with printed earthenware patterns. Bone china uses bone ash in the body, giving a lighter feel, a brighter white, and a gentle translucency at thin edges. Spode’s historical role in the development of English bone china is a key piece of its reputation, tied to late-18th and early-19th century advances. When shopping, the product page or base stamp usually states the material. For antiques, material and stamp together help separate a sturdy earthenware daily plate from a finer bone china serving piece intended for formal use.
