vitreous

Definition

Of or resembling glass; glassy.

Etymology

From Middle French vitreux, from Latin vitreus (“glassy, transparent”), from vitrum (“glass”). The terms vitreous (positive) and resinous (negative) electricity were coined in 1733 by Charles François de Cisternay du Fay, who studied the different behaviour of glass and resin when rubbed with silk and fur, respectively.

Example Sentences

• "Pressing his fingertips against the rippled, vitreous surface, he had the odd sensation that were he to apply sufficient pressure the glass would give way like a permeable membrane, and he would be able to pass right through it, but when he pushed harder, the surface remained cold and unyielding."
