It is allowed to settle; then the clear liquor is drawn ofl into evaporatingvessels. These may be of two kinds. The surface-evaporating furnace, shown in Ji(/. 613, is a very admirable invention for econo-?^ mizing vessels, time, and fuel. The grate, A, and fire-place, are separated from theevaporating laboratory d, bj a doublefire bridge b, c, having an interstitialspace in the middle, to arrest the com-munication of a melting or igniting heattoward the lead-lined cistern D.
