Ground Glass

Ground glass is glass whose surface has been ground to produce a flat but rough (matte) finish.

Ground glass surfaces have many applications, ranging from mere ornamentation on windows and table glassware to scientific uses in optics and laboratory glassware.

Famous quotes containing the words ground and/or glass:

    “To say that authority, whether secular or religious, supplies no ground for morality is not to deny the obvious fact that it supplies a sanction.”
    —A.J. (Alfred Jules)

    “Here in the centre stands the glass. Light
    Is the lion that comes down to drink. There
    And in that state, the glass is a pool.
    Ruddy are his eyes and ruddy are his claws
    When light comes down to wet his frothy jaws”
    —Wallace Stevens (1879–1955)
