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:
“Having interr’d her Infant-birth,
The watry ground that late did mourn,
Was strew’d with flow’rs for the return
Of the wish’d Bridegroom of the earth.”

“Lay down, lay down the bigly bier,
Lat me the dead look on;
Wi’ cherry cheeks and ruby lips
She lay an’ smil’d on him.
O ae sheave o’ your bread, true-love,
An’ ae glass o’ your wine,
For I hae fasted for your sake
These fully day [is] nine.”
—Anna Gordon Brown (1747–1810)
