(11) A good liquid blacking may be prepared by mixing 3 lb. lampblack with 1 qt. stale beer, and 1/2 pint sweet oil, adding thereto 1 oz. treacle, 1/4 oz. green copperas, and 1/4 oz. logwood extract. This furnishes a blacking which polishes easily and well.
To 30 parts syrup, contained in a boiler, add 9 of lampblack and 1 1/2 of finest bone-black, and mix the whole intimately together. Heat 1 1/2 part guttapercha, cut into small pieces, in a kettle over a coal-fire, until it is nearly all melted, add to it gradually, under constant stirring, 2 1/2 parts olive oil, and when the guttapercha is all dissolved, 1/2 part stearin. Pour the latter mixture, while still warm, very slowly and gradually into the first-mentioned mixture, and when the whole has been thoroughly incorporated, add a solution of 2 1/10 part gum Senegal in 6 of water, likewise stirring. Finally, the product may be aromatised by the addition of 1 1/10 part rosemary or lavender oils. This blacking produces a fine gloss of a deep black. It is not injurious to leather.
(14) Take ivory- or bone-black, any quantity, and to every pound put 1 1/2 oz. measure of sulphuric acid, and well triturate it. It will become damp, like snuff. Next add cod oil, 2 oz. to the lb. If liquid add treacle, 3 oz. to the lb., and small beer to mix, or stale beer if for paste, enough to make up into a paste. Foots sugar is preferable to treacle, and a better black is got by adding 1/4 oz. to the lb. of Prussian blue. It is improved if laid up light for a day or two after the first manipulation, and again' after the second, as a decomposition takes place.
(15) A fine, brilliant, elastic dressing for leather can be made as follows: - To 3 lb. of boiling water add, with continual stirring, 1/2 lb. white wax, 1 oz. transparent glue, 2 oz. gum Senegal, 1 1/2 oz. white soap, and 2 oz. brown candy. Finally, add 2 1/2 oz. alcohol, and, after the whole is cooled, 3 oz. fine Frankfort black. The dressing is thinly applied to the leather with a soft brush, and after it is dried it is rubbed with a piece of fine pumice and polished with a stiff brush.
(16) 7 lb. each ivory black and treacle, well mixed with 2 qt. boiling water; add 2 lb. 10 oz. vitriol, and the previously thin liquid will become quite thick. After the effervescence has ceased, add 1 pint of any common oil - fish oil is the best. If you want it liquid, add stale beer or vinegar.
(17) Useful blacking for leather may be made thus: - Dissolve 11 lb. of green vitriol and 5 lb. tartaric acid in 9 gal. water. After the settling, draw off the clear liquid; then boil 16 lb. logwood with about 18 gal. water and 11 gal. of the fluid. Let the boiled mixture stand for about 8 days, pour it off from the sediment, dissolve in it 2 lb. grape sugar, and mix this liquid with the green vitriol solution. The blacking so obtained may be made still brighter by mixing the logwood decoction with 4 lb. aniline black-blue before the addition of the vitriol. The application of the blacking is very simple. The leather is first well brushed with a solution of soda, or still better with a spirit of sal-ammoniac, in 25 times as much water, to get rid of the grease. The blacking is then applied with the proper brush for the purpose.
(18) Finishing Black
Mix together 1/2 oz. each gelatine and indigo, 1 oz. logwood extract, 2 oz. crown soap, 8 oz. softened glue, and 1 qt. vinegar; heat the whole over a slow fire, and stir until thoroughly mixed. Apply with a soft brush, and polish with a woollen cloth.
(19) Mix a quantity of bone-black with equal parts of neats'-foot oil and brown sugar, in proportions to produce a thick paste; then with vinegar and sulphuric acid in proportions of 3 parts of the former to 1 of the latter.
(20) Melt 2 lb. wax, and add 1/4 lb. washed and well-dried litharge by screening it through a fine sieve; then add 6 oz. ivory black, and stir until cool, but not cold; add enough turpentine to reduce it to a thin paste, after which add a little birch or other essential oil to prevent it from souring.
(21) A liquid black is made by mixing 3 oz. ivory black with 1 tablespoonful citric acid, 2 oz. brown sugar, and a small quantity of vinegar, afterward adding 1 oz. each sulphuric and muriatic acids; mix the whole together, and add a sufficient quantity of vinegar to make 1 pint in all.
(22) Vinegar, 2 pints; soft water, 1 pint; glue (fine), 4 oz.; logwood chips, 8 oz.; powdered indigo, 2 dr.; potash bichromate, 4 dr.; gum tragacanth, 4 dr.; glycerine, 4 oz. Boil, strain, and bottle.
(23) A German journal gives the following: - Mix 200 parts shellac with 1000 of spirit (95 per cent.) in a well-stoppered bottle. Keep in a warm place for 2-3 days, shaking frequently. Separately dissolve 25 parts Marseilles soap in 375 of warmed spirit (25 per cent.), and to the solution add 40 of glycerine. Shake well and mix with the shellac solution. To the mixture add 5 parts nigrosin dissolved in 125 of spirit. Well close the vessel and shake energetically, and then leave the mixture in a warm place for a fortnight.
(24) Ivory black, 6 lb.; treacle, 4 lb.; gum arabic (dissolved in hot water), 2 oz.; vinegar, 2 gal.; sulphuric acid, 2 1/2 lb.; indiarubber dissolved in about 1 pint of oil, 2 oz. Mix well together. This blacking may be applied by means of a brush, or a small sponge attached to a piece of twisted wire.
(25) Boot Top Liquid
Oxalic acid, 1 oz.; white vitriol, 1 oz.; water, 30 oz. Dissolve, and apply with a sponge to the leather, which should have been previously washed with water; then wash the composition off with water, and dry. This liquid is poisonous.
(26) A waterproof blacking, which will give a fine polish without rubbing, and will not injure the leather: - 18 parts beeswax, 6 spermaceti, 66 turpentine oil, 5 asphalt varnish, 1 powdered borax, 5 vine twig (Frankfort) black, 2 Prussian blue, 1 nitro-benzol. Melt the wax, add powdered borax, and stir till a kind of jelly has formed. In another pan melt the spermaceti, add the asphalt varnish, previously mixed with the turpentine oil, stir well, and add to the wax. Lastly add the colour previously rubbed smooth with a little of the mass. The nitro-benzol gives fragrance.
