Shell-lac Cement

Fine orange shell-lac, bruised, 4 oz., highly rectified spirit 3 oz. Digest in a warm place, frequently shaking, till the shell-lac is dissolved. Methylated spirit may be substituted for spirit of wine, where the smell is not objectionable. A most useful cement for securely joining almost any material. See Glue, Liquid.

Shell-lac Cement without Spirit

Boil 1 oz. of borax in 16 oz. water, add 2 oz. powdered shell-lac, and boil in a covered vessel till the lac is dissolved. Cheaper than the above, and for many purposes answers very well. Both are useful in fixing paper labels to tin, and to glass when exposed to damp.

Cheese Cement, for Earthenware, etc

Glass Flux, for mending broken China, etc

In liquid chloride of zinc marking from 50° to 60° of Baume's areometer, dissolve 3 per cent. of borax or sal ammoniac: add oxide of zinc which has been heated to redness, until the mass is of a proper consistence. The cement, when hard, becomes as firm as marble. It may be cast in moulds, like plaster of Paris, or used in the construction of mosaic works, etc. - M. SOBEL,
