Flint
Flint is a hard, sedimentary cryptocrystalline form of the mineral quartz, categorized as a variety of chert. It occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones. Inside the nodule, flint is usually dark grey, black, green, white, or brown in colour, and often has a glassy or waxy appearance. A thin layer on the outside of the nodules is usually different in colour, typically white and rough in texture. From a petrological point of view, "flint" refers specifically to the form of chert which occurs in chalk or marly limestone. Similarly, "common chert" (sometimes referred to simply as "chert") occurs in limestone.

Famous quotes containing the word flint:
“Without passion man is a mere latent force and possibility, like the flint which awaits the shock of the iron before it can give forth its spark.”
—Henri-Frédéric Amiel (1821–1881)
“I see you boys of summer in your ruin.
Man in his maggot’s barren.
And boys are full and foreign in the pouch.
I am the man your father was.
We are the sons of flint and pitch.
O see the poles are kissing as they cross.”
—Dylan Thomas (1914–1953)
“O sovereign mistress of true melancholy,
The poisonous damp of night disponge upon me,
That life, a very rebel to my will,
May hang no longer on me. Throw my heart
Against the flint and hardness of my fault,
Which, being dried with grief, will break to powder
And finish all foul thoughts. O Antony,
Nobler than my revolt is infamous,
Forgive me in thine own particular,
But let the world rank me in register
A master-leaver and a fugitive.”
—William Shakespeare (1564–1616)
