The following are a few recipes for making uncoranion inks, which may be used by fancy writers; and as they are not to be found on sale, they must be very useful to some of our readers:-
Gold Ink. - Mosaic gold, 2 parts; gum arabic, 1 part; are rubbed up with water until reduced to a proper condition.
Silver Ink. - Triturate in a mortar equal parts of silver foil and sulphate of potassa, until reduced to a fine powder; then wash out the salt, and mix the residue with a mucilage of equal parts of gum arabic and water.
Brown Ink. - Digest powdered catechu, 4 parts, with water, 60 parts, for some hours; filter and add sufficient of a solution of bichromate of potassa, part in 16 of water.
Yellow Ink. - Macerate gamboge, 1 part (or ½); alum, ½ part; gum arabic 1 part, in acetic acid, 1 part; and water 24 parts.
Blue Ink. - Triturate best Prussian blue, 6 parts, with a solution of 1 part of oxalic acid in 6 of water, and towards the end of a quarter of an hour or so, add gradually gum arabic, 18 parts, and water, 280. Pour of clear.
Red Inks. - 1. Pernambuco wood, 4 parts; alum and cream of tartar, of each, 1 part, with 30 of water; boil down to 16 parts, let stand, pour off, filter and dissolve in the liquid gum arabic, 1½ parts, white sugar, 1 part.
2. Digest powdered cochineal, 8 parts, and sal tartar. 16 parts in 144 of water, for 24 hours. Then biul up with powdered (potash) alum, 4 parts, and add 24 of cream of tartar, with 3 parts of tartaric acid, and when effervescence has ceased, another part of the acid, or enough to produce the color. Let cool, filter, and boil the residue on the filter with 12 parts of water; filter again, mix the liquids and dissolve in them 24 parts of gum arabic, and lasly 1/3 part of oil of cloves. No iron vessels must be used in this process.
3. Digest powdered cochineal, 10 parts; oxalic acid, 2 parts; dilute acetic acid, 80 parts; distilled water, 40 parts for 36 hours. Then add powdered alum, 1 part; gum arabic, 1 to 10, shake up, let stand for 12 hours and strain.
4. Dissolve 1 part of carmine in 8 to 10 parts of aqua ammonia, and add mucilage of gum arabic sufficient to reduce it properly.
Violet Ink. - 8 parts of logwood and 64 parts of water; boil down to one-half, then strain and add 1 part of chloride of tin.
Green Inks. - 1. Digest 1 part of gamboge with from 7 to 10 parts of the blue ink.
2. To powdered bichromate of potassa, 8 parts contained in a porcelain dish, add oil of vitriol, 8 parts, previously diluted with 64 of water; then heat and while evaporating add gradually 24 parts of alcohol, and reduce to 56 parts, which filter, and in the clear liquid dissolve 8 parts of gum arabic.
Crimson Ink. - A beautiful crimson ink is made by mixing red ink, No. 1, with the violet ink; about equal parts will answer.
The parts given are those of weight, not measure. The mucilage of gum arabic prevents the pine particled of color falling to the bottom in the form of sediment. Sugar gives to inks a glossy appearance, but very little of it should be used, as it is liable to make the ink sticky.
