VI.—A paste with which wall paper can be attached to wood or masonry, adhering to it firmly in spite of dampness, is prepared, as usual, of rye flour, to which, however, are added, after the boiling, 8 1/3 parts, by weight, of good linseed-oil varnish and 8 1/3 parts, by weight, of turpentine to every 500 parts, by weight.
VII.—Paste for Wall Paper.—Soak 18 pounds of bolus (bole) in water, after it has been beaten into small fragments, and pour off the supernatant water. Boil 10 ounces of glue into glue water, mix it well with the softened bolus and 2 pounds plaster of Paris and strain through a sieve by means of a brush. Thin the mass with water to the consistency of a thin paste. The paste is now ready for use. It is not only much cheaper than other varieties, but has the advantage over them of adhering better to whitewashed walls, and especially such as have been repeatedly coated over the old coatings which were not thoroughly removed. For hanging fine wall paper this paste is less commendable, as it forms a white color, with which the paper might easily become soiled if great care is not exercised in applying it. If the fine wall paper is mounted on ground paper, however, it can be recommended for pasting the ground paper on the wall.
Label Pastes:
Pastes To Affix Labels To Tin.
The following formulas for pastes of the type indicated were proposed by Leo Eliel:
| I.— | Tragacanth | 1 ounce |
|---|---|---|
| Acacia | 4 ounces | |
| Thymol | 14 grains | |
| Glycerine | 4 ounces | |
| Water, sufficient to make | 2 pints |
Dissolve the gums in 1 pint of water, strain, and add the glycerine, in which the thymol is suspended; shake well and add sufficient water to make 2 pints. This separates on standing, but a single shake mixes it sufficiently for use.
| II.— | Rye flour | 8 ounces |
|---|---|---|
| Powdered acacia | 1 ounce | |
| Glycerine | 2 ounces | |
| Oil of cloves | 40 drops |
Rub the rye flour and acacia to a smooth paste with 8 ounces of cold water; strain through cheese cloth, and pour into 1 pint of boiling water, and continue the heat until as thick as desired. When nearly cold add the glycerine and oil of cloves.
| III.— | Rye flour | 5 parts |
|---|---|---|
| Venice turpentine | 1 part | |
| Liquid glue, a sufficient quantity | ||
