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:
“One need not be a great beau, a seductive catch, to do it effectively. Any man is better than none. To shrink from giving so much happiness at such small expense, to evade the business on the ground that it has hazards—this is the act of a puling and tacky fellow.”
—H.L. (Henry Lewis)
“... this I conceive to be no time to prate of moral influences. Our men’s nerves require their accustomed narcotics and a glass of whiskey is a powerful friend in a sunstroke, and these poor fellows fall senseless on their heavy drills.”
—Clara Barton (1821–1912)
