Without a regular structure. Amorphous minerals do not have a repeating crystalline matrix. Glass, for example, is amorphous because it is cooled in the kiln quickly enough that no crystals have an opportunity to form.

Glass vs. Crystalline
In ceramic technology the term 'glass' is contrasted with the crystalline state, it is seen as a "super-cooled liquid". When crystalline materials solidify the molecules have opportunity to orient themselves in the preferred pattern during freezing whereas in a glass the random orientation of molecu...
When ceramic melts are cooled they prefer to solidify as an organized molecular structure. Given sufficient time and sympathetic chemistry, they will form a crystalline structure. But if cooling is faster they solidify as a glass.
Crystals can grow in cooling glaze melts if one or more of the fol...
