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:

    “If there were one who lived wholly without the use of money, the State itself would hesitate to demand it of him. But the rich man—not to make any invidious comparison—is always sold to the institution which makes him rich.... Thus his moral ground is taken from under his feet.”
    —Henry David Thoreau (1817–1862)

    “The awaited scream rises,
    the shattering
    of glass and the cracking
    of bone
    a polar tumult as when
    black ice booms....”
    —Denise Levertov (b. 1923)
