Amorphous solids can best be described by what they are not. They are materials that exhibit elastic response like crystalline solids, but possess no crystal‐like long‐range order in the spatial arrangements of their atoms. Amorphous materials could be inorganic or organic and are also known as glasses and vitreous solids. Glasses are increasingly being used in wide‐ranging branches of science and technology. Bulk amorphous metals (aka metallic glasses) are increasingly being used as engineering materials owing to their extraordinary isotropic properties, including high strength, corrosion resistance, formability, and even biocompatibility (Khan et al. 2017; Jafary‐Zadeh et al. 2018). Molten minerals quenched to an amorphous state are used as analogs for magma (molten rocks) deep inside the surface of Earth (Davidovits 2005).
