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:
“Like plowing, housework makes the ground ready for the germination of family life. The kids will not invite a teacher home if beer cans litter the living room. The family isn’t likely to have breakfast together if somebody didn’t remember to buy eggs, milk, or muffins. Housework maintains an orderly setting in which family life can flourish.”
—Letty Cottin Pogrebin (20th century)
“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)
