Smoke
Smoke is a collection of airborne solid and liquid particulates and gases emitted when a material undergoes combustion or pyrolysis, together with the quantity of air that is entrained or otherwise mixed into the mass. It is commonly an unwanted by-product of fires (including stoves, candles, oil lamps, and fireplaces), but may also be used for pest control (cf. fumigation), communication (smoke signals), defensive and offensive capabilities in the military (smoke-screen), cooking (smoked salmon), or smoking (tobacco, cannabis, etc.). Smoke is used in rituals, when incense, sage, or resin is burned to produce a smell for spiritual purposes. Smoke is sometimes used as a flavoring agent, and preservative for various foodstuffs. Smoke is also a component of internal combustion engine exhaust gas, particularly diesel exhaust.

Famous quotes containing the word smoke:
“As far as I can see, this autumn haze
That spreading in the evening air both ways
Makes the new moon look anything but new
And pours the elm-tree meadow full of blue,
Is all the smoke from one poor house alone....”
—Robert Frost (1874–1963)
“O women, kneeling by your altar-rails long hence,
When songs I wove for my beloved hide the prayer,
And smoke from this dead heart drifts through the violet air
And covers away the smoke of myrrh and frankincense;
Bend down and pray for all that sin I wove in song....”
—William Butler Yeats (1865–1939)
“Smoking ... is downright dangerous. Most people who smoke will eventually contract a fatal disease and die. But they don’t brag about it, do they? Most people who ski, play professional football or drive race cars, will not die—at least not in the act—and yet they are the ones with the glamorous images, the expensive equipment and the mythic proportions. Why this should be I cannot say, unless it is simply that the average American does not know a daredevil when he sees one.”
—Fran Lebowitz (b. 1950)
