Brass-tempering
Brass containing the least zinc is the softest and most easily wrought but, with a proportion of one fourth, brass is still perfectly malleable when cold. Hammering increases or creates elasticity in brass, destroys its flexibility, adds considerably to its durability, and imparts magnetic power. If it is desired to draw the temper again, heat to a cherry-red, and immerse the article in water. See BRASS; TEMPERING. Brass to Dull.--See DULLED BRASS.
