Preserved examples of various forms of spoons used by the ancient Egyptians include those composed of ivory, flint, slate and wood; many of them carved with religious symbols. During the Neolithic Ozieri civilization in Sardinia, ceramic ladles and spoons were already in use. In Shang Dynasty China, spoons were made of bone. Early bronze spoons in China were designed with a sharp point, and may have also been used as cutlery. The spoons of the Greeks and Romans were chiefly made of bronze and silver and the handle usually takes the form of a spike or pointed stem. There are many examples in the British Museum from which the forms of the various types can be ascertained, the chief points of difference being found in the junction of the bowl with the handle.
