Amorphous

Amorphous (Gr. a, 'not,' morphē, 'form'), shapeless. In Chemistry, the term amorphous is used to describe the uncrystallised, in opposition to the crystallised, condition of bodies. There are substances which, in certain conditions, are capable of crystallisation, but in other conditions remain amorphous. Thus, pure sugar contains carbon, which appears as an amorphous substance after the sugar has been burned in a platina crucible. The same substance, carbon, appears in its crystallised form in the diamond.
