Glass-en-am′el.
This is applied to a semi-lucid or an opaque glass, which owes its milkiness to the addition of binoxide of tin. The transparencies which are hung in windows or form shades for lamps are of the semi-lucid character, and are miscalled porcelain transparencies. Watch-dials have an opaque, glass-enameled face on a metallic backing. See enamel.Glass-Engrarers' lathe. |
