Mineral Fusible Cement. 85 
A. Iron kettle or pot, for melting, on either a coal or coke fire. 
B. Ladle for taking out the cement, and other purposes. 
C. Small kettle to contain so much cement from the large kettle A, 
as may be used in twelve minutes. 
D. Fine wire brush for using the cement in a pure state, when 
coating or lining tanks, bottoms of boats, &c. 
E. Roller to be used for making fair surfaces. 
F. Machine used when doing horizontal work, (such as floors, &c.) 
and followed by the roller E, to make the fair surface.* 
. An iron for remedying irregularities of surface of new work or 
filling in and making good to settlements straight joints and other simi- 
lar purposes. 
H. A vessel to be used for filling in joints, and difficult parts. 
N. B.—The common bricklayer’s trowel, can be used when the 
cement is guaged with sand; but when used in its pure state for 
building brickwork, the best mode is to dip the bricks into the kettle ; 
as by so doing, the whole surface will be covered, and yet nothing 
wasted.

spread it well to the depth of one fourth of an inch. The vessel is to be tilted in this 
ease, by means of the ete below at (6). a stiffened by cooling, the cement 
is easily warmed again : 
+ The dipping, itis presumed, need be applied only to the sides of the bricks, or at 
least not to their faces, unless the bricks be porous.
