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

Famous quotes containing the words ground and/or glass:
“The professional celebrity, male and female, is the crowning result of the star system of a society that makes a fetish of competition. In America, this system is carried to the point where a man who can knock a small white ball into a series of holes in the ground with more efficiency than anyone else thereby gains social access to the President of the United States.”
—C. Wright Mills (1916–1962)
“My glass shall not persuade me I am old
So long as youth and thou are of one date,
But when in thee time’s furrows I behold,
Then look I death my days should expiate.”
—William Shakespeare (1564–1616)
