Red Cement

The red cement used for uniting glass to metals, is made by melting five parts of black resin and one part of yellow wax; when entirely melted, stir in gradually, one part of red ochre, or Venetian red in fine powder, and previously well dried. This cement should be melted before it is used, and it adheres better if the objects to which it is applied are warmed.

Glue For Uniting Cardboard, Etc

For uniting cardboard, paper, and small articles of fancy-work, the best glue, dissolved with about one third its weight of coarse brown sugar in the smallest quantity of boiling water, is very good. When this is in a liquid state, it may be dropped in a thin cake upon a plate, and allowed to dry. When required for use, one end of the cake may be moistened by the mouth, and rubbed on the substances to be joined.

Flour Paste

The uses of flour paste are very well known. But it will be found a great improvement to add a little alum to it before boiling; it will then work more freely, the particles of flour will not separate from the water, and it will unite surfaces much more firmly.

A paste to resist the attacks of insects may be made by omitting the alum, and putting to each half pint of paste, fifteen grains of corrosive sublimate in powder, and well mixing it. This paste is poisonous.

Rice Glue

Rice glue is a very delicate and suitable article for fancy work. Thoroughly mix rice flour with cold water, let it simmer gently over a slow fire. This is excellent for joining paper, etc., and if properly made and applied, the joining will be found very strong. When dry it is almost transparent.

Cement For Mending Stone, Etc

Mastic Cement

Mastic cement, or mastic glue, suitable for china, glass, the finer stones, marbles, or even for metals, is made as follows: To one ounce of mastic, add as much highly rectified spirits of wine as will dissolve it. Soak an ounce of isinglass in water till quite soft, then dissolve it in pure rum or brandy until it forms a strong glue, to which add about a quarter of an ounce of gum ammoniac, well rubbed, and mixed. Put the two mixtures together in an earthen vessel over a gentle heat, and when well united, put into a small bottle and keep it well stopped. When wanted for use, the bottle must be set in warm water, and the china or glass articles must be warmed before the cement is applied. The broken surfaces, when carefully fitted, should be kept in close contact for twelve hours at least, until the cement is fully set, after which the fracture will be as secure as any part of the vessel, and scarcely perceptible.

How To Mend Alabaster Ornaments

As alabaster objects are composed of several parts, they are liable, from a variety of causes, to become disjoined, and when this occurs the parts may be rejoined by a cement made from the white of one egg mixed with a teaspoonful of quicklime. The cement should be used immediately that it is mixed, and the parts to be joined should be previously damped with lukewarm water.

Cement For Leather

An adhesive material for joining leather, cloth, etc., is made as follows: Take one ounce of gutta percha, four ounces of India rubber, two ounces of pitch, one ounce of shellac, and two ounces of oil. Melt these ingredients together and use the mixture while hot.
