To prevent change of form and to give the greatestedge strength, all excess of mercury must be removed in mixing.

(2) Mix thoroughlywith the pestle (Fig. 175) until the alloy and mercury are com-pletely incorporated. (3) Remove to the dry and clean palmof the left hand and work vigorously, rapidly and continuouslywith the fingers of the right hand for from three to five min-utes, squeezing frequently and removing excessive mercuryuntil a characteristic cry of the mass is heard when in closeproximity to the ear. (4) With the thumb and forefinger,forcibly squeeze out all remaining excess of mercury; or.
