The technology of manufacturing special
The name of these inks is completely wrong, since Alizarin does not enter into their composition. Alizarin ink makes preparations from the drawing of ink nuts, and they contain acetic acid. In ordinary ink, the dye is in minute particles floating in the liquid. In alizarinic inks, the presence of a significant portion of acid in them also does not result in the formation of sludge. Acetic acid, which is part of the ink, dissolves also maintains a colorant in the dissolved form, so there is no way to settle the alizarin ink completely or approximately. However, they have a small flaw, which consists in the fact that they dry up quickly, because of what they form on a thick mass, they also have to wipe the feather with a cloth.
For the preparation of office alizarinic ink take:
10 parts of ink, 6 parts of ferrous sulfate,
1 part of gum arabic,
100 parts of vinegar,
20 parts indigo-carmine solution.
The crushed peanut is insisted in vinegar for 4-6 days. Kuporos also gum arabic is dissolved separately in vinegar, and it is necessary to boil them once. Later, as the liquids are merged together, they are also filtered, an indigo-carmine solution is added. The final should not be added at once a large amount, but gradually with each addition, stir the solution.
Aniline paints, which were so widely used in modern techniques of dyeing, also served as a preparation material for ink. Nuts, Kampeshevo logs, iron vitriol, etc., used earlier for the preparation of ink, now retreated to the rear schedule. To obtain aniline ink is taken a well-known aniline pigment also dissolves in water. This solution does not have to be concentrated in any way, because at that time the ink will quickly dry out and also remain unstable on paper. If the concentration is correct, the aniline ink is stable, it easily drains from the pen, does not corrode steel feathers, does not so quickly become thick and does not become covered with mold.
a) Black ink. Dissolve 1 part of the dissolved in water nigrosin or black Reform-schwarz in 10 parts of hot water. In the resulting solution add a solution of 2 parts of gum arabic, diluted in 10 parts of cold water.
b) Red ink. For their preparation take 2 elements of fuchsin or eosin also dissolve in 90 parts of hot water. On cooling, add 2 elements of gum arabic, diluted in 10 parts of cold water.
c) Blue ink. To prepare them take 5 parts resorcinol, pour 30 parts of cold water, but after 2 hours add 640 parts of hot water, in which 20 parts of sugar is dissolved, and 1 share of crystalline oxalic acid. All together well shake, leave not to move a few days also filter.
d) Purple ink. For their preparation, take 10 elements of methyl-fiber, pour 30 parts of cold water, leave for 3-4 hours and add 950 elements of hot water, 10 parts of sugar in powder, also 2 elements of crystalline oxalic acid. Within a period of 2-3 days, the mashing is agitated and then filtered.
e) Green ink. For their production take 1 part of the water soluble green aniline paint also dissolve it in 100-200 parts of boiling water. To get a thicker green color, you can add a little picric acid.
Take 200 pieces of shellac, 300 elements of borax, 3000 parts of hot water, dissolve with heating, filter also add a solution of 100 parts of water nigrosine, 1 picric acid, 3 elements of tannin, 150 parts of ammonia and 75 parts of distilled water.
Hectographic ink is a viscous solution of aniline paint, through which it is possible to obtain, with a hectograph, a mass of prints. The main role here is played by glycerin, which prevents rapid drying of ink.
Making a hectograph
First of all, you need to take the selected grade of carpentry glue, having done with it the preliminary test. Take a small piece of glue and dip it into the water at room temperature. If the glue in the water disperses, then it is in no way suitable for making hectographic mass; If it turns into a gelatinous mass, the glue is suitable for making a hectograph.
500 g of this joiner's glue also 1 kg of technical glycerine is lowered into a newly made tin bowl, in which there should not be the slightest presence of fat. First the glycerin is poured, also brought through a gradual heating to the state at what time the steam will rise from it. Then the carpenter's glue is lowered into the kettle, turned by the act of water into jelly, and the pot is again put on the stove. Heating lasts until the glue is dissolved in glycerin with gentle stirring, so that no air bubbles form. When the heated mass turns yellow, it is poured into a flat zinc box with well-sealed edges of 2-2.5 cm high and left not to move on an even surface until completely cooled, and the hectograph is also ready. If during the transfusion of the mass from the kettle into the zinc box, bubbles form on the surface of the mass, then they can be destroyed by holding a burning ray above them. If the hectographic mass came out extremely strong, and the ink does not stick to it, then it is necessary to melt the whole mass again, adding 50-60 g of glycerin. If you do not have a good carpentry glue at hand, it can be replaced with gelatin. To prepare the mass, 2 kg of gelatin is taken, which is dissolved in 3 kg of technical glycerin with addition of 400 g of talc in powder.
The recipe for preparing a hectographic mass
500 g of gelatin is dissolved in 3 liters of water when heated, during which 6 kg of technical glycerin is added, and 500 g of sulfur borate salt in the powder.
For the preparation of ordinary stationery or school ink by means of infusion or drawing on cold water, take:
3 parts of ink nuts,
2 parts of iron sulfate,
2 parts of gum arabic,
60 parts of water.
The nut is poured into powder and, pouring into a glass bottle, is poured over with water.
In another vessel iron sulphate and gum arabic are dissolved separately. The infusion of the nut must not move for several days, until the water extracts all the tannin from it, whereas as the vitriol also gum arabic is completely dissolved within a few hours. Both solutions are poured together, mixed well and, if left standing for a day or a couple, carefully drained to separate the liquid from the precipitate.
Copying ink is prepared in the same way as if it were ordinary ink, but they act more concentrated in the content of the dye. In addition, sugar is also added to glycerin, a substance that maintains moisture. From this they acquire the property not to be absorbed into the paper and also, when touching the imperfectly dried message with a moist tissue paper, to separate a particle of the dye substance from itself. The amount of both substances is best determined on the samples.
To test copying ink, it is necessary to put a tissue paper (or oilcloth) on a sheet of thick wax paper (also an oilcloth) and water it with water using a wide brush or a sponge. Then cover with a piece of paper, and all this put in a thick book and also push hard to remove excess dampness. Later, put a written sheet of paper, cover it with tissue paper, and put it all back into the book also firmly.
Copying inks for typewriters
Take 3 soap elements, 12.5 glycerin elements, 36 parts water also dissolve when heated. In a friend's vessel, dissolve the right amount of any aniline paint in 72 parts of alcohol and mix the two liquids.
Paint for typewriters
In a porcelain cup, 100 g of glycerin is heated and 100 g of methyl ether are gradually added to the heated glycerin. Later, the mass is cooled and carefully added a little water, stirring non-stop. Water is poured in order to eliminate the granularity of the mass. As soon as the mass takes the form of a viscous bright liquid, the addition of water is stopped. The tape for the typewriter is pulled through this paint and rolled between smooth rollers under strong pressure.
Lithographic inks are used by lithographers to make croutons with a stylus directly on a flint or on a transfer paper.
1. Austrian ink.
For their preparation take:
600 parts of yellow wax,
125 parts of shellac,
75 parts fat,
300 pieces of snow-white soap,
100 parts of mastic,
25 parts of resin,
75 parts of Dutch soot.
To the melted pre-wax, add finely chopped soap and heat until the mass begins to emit an undesirable odor. When cooking, you must be very careful, in case of ignition, the flame is drowned in the lid. And then, at what time the mass will slightly cool, it is poured into molds.
Lithographic inks, as it is known, are preserved in pieces (like Chinese ink) also only by measure of need are ground on a saucer with water to the required density. The good quality of this mass is in many respects sieve from sufficient incandescence of it, so that it is neither greasy nor lean. Both flaws prevent the translation of drawings or font on a lithographic stone.
2. English ink
For their preparation take:
60 parts of yellow wax,
60 pieces of snow-white soap,
80 parts of mastic,
60 parts fat,
120 parts shellac,
10 parts of Venetian turpentine,
11 parts of Dutch soot.
Mastic and shellac put in warmed terpentine, then add lard, wax, soap and soot. All this is well mixed and is rubbed up. The cooled also slightly hardened mass is spread on a nasty flint or glass and cut into bars.
Ink for labeling laundry
Good ink for the label of laundry can be prepared from aniline paints.
Black ink. Take 1 share of nigrosine, soluble in water, 1.5 elements of hydrochloric acid, 22 elements of alcohol. To this solution is added a solution of 7.5 gum arabic elements in 100 parts of cold water.
Red ink. Prepared like, only instead of nigrosin take fuchsin or eosin.
Inks for writing on metals
For writing on zinc take:
15 parts of copper sulphate,
10 parts of potassium chloride,
14 parts of water.
To write on copper also tin:
25 parts of copper sulfate,
10 parts of gum arabic,
5 parts of soot,
10 parts hydrochloric acid,
24 parts of ammonia,
26 parts of water.
To write on iron also became:
20 parts of copper sulphate,
5 parts of vinegar,
5 parts of soot,
10 parts of gum arabic,
60 parts of water.
For writing on tin:
10 parts of copper sulphate,
20 parts of water,
a few drops of hydrochloric acid,
a little gum arabic.
For writing on glass
3 parts of barium sulphate are mixed with 1 part of ammonium chloride and as much sulfuric acid is added to the mixture to form a semi-liquid mass. Since such ink corrodes the glass, it is possible to protect them only in bottles, smeared with paraffin.
Such paint should alienate clean, clear prints and should not dry up on the stamp in any way. Stamp paint is made in different colors, but the most common is purple. The easiest way to act it out of aniline paints.
We give the tested composition of violet stamping paint:
10 parts of methyl violet,
3 parts of gum arabic,
1 part of glycerin,
2 parts of water.
Gum arabic is dissolved in cold water and mixed with glycerin, the powder in the powder is put in a flat-bottomed porcelain mortar and also ground with a porcelain pestle, adding a little gum arabic with glycerin. To obtain other colors, take the appropriate paint, for black - nigrosine, for red magenta, etc.
