Origin of vitreous
- From Latin vitreus from vitrum glass
From American Heritage Dictionary of the English Language, 5th Edition
- The terms vitreous (positive) and resinous (negative) electricity were coined in 1733 by Charles FranÃ§ois de Cisternay du Fay, who studied the different behaviour of glass and resin when rubbed with silk and fur, respectively.
- From Latin vitreus (“glassy, transparent"), from vitrum (“glass").
