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)
“More Safe, and much more modest ‘tis, to say
God wou’d not leave Mankind without a way:
And that the Scriptures, though not every where
Free from Corruption, or intire, or clear,
Are uncorrupt, sufficient, clear, intire,
In all things which our needfull Faith require.
If others in the same Glass better see
‘Tis for Themselves they look, but not for me:
For MY Salvation must its Doom receive
Not from what OTHERS, but what I believe.”
—John Dryden (1631–1700)
