Granulation

(gran-u-la's hun.) [From L. granum, a grain.] (Metall.) A proce by which metal is formed into granular ma es; performed, generally, by pouring the metal, while in a fluid state, into water. Should it require to be finely triturated, it must be made to pa through a perforated ladle or sieve. If the particles are intended to be spherical, it must be poured from such a height that they will be cold before reaching the water: -shot is made in this manner-hence the great altitude of the structures called shot-towers.-(Med.) The minute, grain-like, fleshy bodies which form on the surfaces of ulcers and suppurating wounds, and serve both for filling up the cavities and bringing nearer together and uniting their sides. The color of healthy granulations is a deep florid red, and they always have a tendency to unite. When livid, they are unhealthy, and have only a languid circulation. [s. 420]
