Nitro-benzole, which is the chemical name for this artificial otto of almonds, has a different odor to the true otto of almonds, but it can nevertheless be used for perfuming soap.
A factory which distilled a good standard tar for roofing paper recovered, besides benzole and naphtha, also about ten per cent. of creosote oil, used for one hundred parts raw paper, 176.4 partially distilled tar.
Another method which the writer recommends is the following, due to Mr. Swan: Immerse a sheet of paper in a solution of India rubber, 4: 100 of benzole, and let dry, which requires a few minutes.
To transfer, soak the proof in tepid water, apply it on the material prepared, as it will be explained further on, and when dry, imbue the support from the back with benzole, to soften the India rubber, and strip.
The plates can be developed on the plates so waxed, but for “full gloss,” that is, for enameled pictures, a film of collodion is applied on the plates, which then, instead of being waxed, should to be simply flowed with a solution of India rubber 1 to 100 of benzole:
Get a large wide-mouthed bottle and pour the balsam and benzole into it.
Take hold of the slide by one corner and pour on to it a sufficient quantity of the balsam and benzole to cover it.
Then after exposure, brush over the India rubber solution on the carbon tissue, apply upon it the support when the benzole is evaporated, and pass the whole under a rolling press to secure adhesion, then develop.
Then pour back all the superfluous varnish into the bottle from one corner of the slide; the varnish remaining will rapidly harden, as the benzole evaporates quickly, and the hardening may be hastened by applying a little heat, but while hardening the slides should be protected from dust.
For tranferring on any material, a sheet of paper is immersed in a solution of India rubber cement in 20 parts of benzole, dried, coated with the gelatine solution, sensitized, etc., by operating in the ordinary manner.
