400. _Cement for Alabaster._

Take of white bees' wax one pound, of rosin a pound, and three quarters

of alabaster. Melt the wax and rosin, then strew the alabaster over it

lightly, (which should be previously reduced to a fine powder.) Stir the

whole well together, then knead the mass in water, in order to

incorporate the alabaster thoroughly with the rosin and wax. The

alabaster, when mended, should be perfectly dry, and heated. The cement,

when applied, should also be heated. Join the broken pieces, bind them,

and let them remain a week. This composition, when properly managed,

forms an extremely strong cement.
