The term "lead crystal" is, by technicality, not an accurate term to describe "lead glass", as glass, anamorphoussolid, lacks a crystalline structure.

As the temperature increases, anamorphoussolidwill become less viscous.

In the limit of small crystallites, as the volume fraction of grain boundaries approaches 100%, the material ceases to have any crystalline character, and thus becomes anamorphoussolid.

Solids that are neither crystalline nor polycrystalline, such as glass, are called "amorphous solids", also called glassy, vitreous, or noncrystalline.
