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:

    “Rational free spirits are the light brigade who go on ahead and reconnoitre the ground which the heavy brigade of the orthodox will eventually occupy.”
    —G.C. (Georg Christoph)

    “Our ideal ... must be a language as clear as glass—the person looking out of the window knows there is glass there, but he is not concerned with it; what concerns him is what comes through from the other side.”
    —Elizabeth Bowen (1899–1973)
