Metallic ones are rare, and mainly used in expensive golf club heads. These hard states are not in statistical equilibrium, so things like the temperature are not well defined, and their thermodynamic quantities vary depending on the past thermal history of a sample. In particular, the transition temperature at which they form is dependent on the rate at which they are cooled. Their zero- temperature thermodynamic entropy is nonzero, which is not a violation of the Third Law because they are not crystals. Examples include cold silly putty and cold chewing gum. For ten points, name these often brittle amorphous solids, whose most common example is formed from chains of silica tetrahedra.
