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:
“Memory is not an instrument for exploring the past but its theatre. It is the medium of past experience, as the ground is the medium in which dead cities lie interred.”
—Walter Benjamin (1892–1940)
“They are, as it were, train-bearers in the pageant of life, and hold a glass up to humanity, frailer than itself. We see ourselves at second-hand in them: they show us all that we are, all that we wish to be, and all that we dread to be.... What brings the resemblance nearer is, that, as they imitate us, we, in our turn, imitate them.... There is no class of society whom so many persons regard with affection as actors.”
—William Hazlitt (1778–1830)
