2496. Cement for Broken China, Glass, &c.
This cement being nearly colourless, possesses advantages which liquid glue and other cements do not.—Dissolve half an ounce of gum acacia, in a wineglass of boiling water; add plaster of Paris sufficient to form a thick paste, and apply it with a brush, to the parts required to be cemented together.

2497. Lime and Egg Cement
Lime and Egg Cement is frequently made by moistening the edges to be united with white of egg, dusting on some lime from a piece of muslin, and bringing the edges into contact. A much better mode is to slake some freshly-burned lime with a small quantity of
boiling
water; this occasions it to fall into a very fine dry powder, if excess of water has not been added. The white of egg used should be intimately and thoroughly mixed, by beating with an equal bulk of water, and the slaked lime added to the mixture, so as to form a thin paste, which should be used speedily, as it soon sets. This is a valuable cement, possessed of great strength, and capable of withstanding boiling water. Cements made with lime and blood, scraped cheese, or curd, may be regarded as inferior varieties of it.
