An Amorphism, in chemistry, crystallography and, by extension, to other areas of the natural sciences is a substance or feature that lacks an ordered form. In the specific case of crystallography, an amorphism is a material that lacks long range crystalline order at the molecular level. In the history of chemistry, amorphism was recognised even before the discovery of the nature of the atomic crystalline lattice. The concept of amorphism can also be found in the fields of art, biology, archaeology and philosophy as a characterisation of objects without form, or with random or unstructured form.
