Alizarin ink

The name of this ink is completely wrong, since alizarin does not enter into their composition. Alizarin inks make preparations from the extract of ink nuts, and in their composition is acetic acid. In ordinary inks, the dye substance is in the smallest particles floating in the liquid. In the alizarin inks, the presence of a significant portion of the acid and glue for the formation of sludge in no way results from the presence of ink. Acetic acid, which is part of the ink, also dissolves the dye in solution, therefore there is no sludge in alizarin inks at all or there is no way at all. However, they have a small flaw, which consists in the fact that they quickly dry up, which is why they have to wipe the pen with a cloth to form a thick mass.

For the preparation of office Alizarin ink take:

  • 10 parts of ink nut, 6 parts of ferrous sulfate,

  • 1 part gum arabic,

  • 100 pieces of vinegar,

  • 20 parts of indigo carmine solution.

Pounded nutlet insist in vinegar for 4-6 days. The vitriol is also dissolved as gum arabic separately in vinegar, and it is necessary to boil them once. After the fluids are merged together, they are also filtered, and an indigo-carmine solution is added. The final one should not be added at once a large amount, however, gradually mix the solution with each addition.

Aniline ink

Aniline dyes, which have received such wide distribution in modern technique of dyeing art, also served as material for ink preparation. Ink nuts, a log log, iron sulfate, etc., which were previously used to prepare the ink, now retreated to the rear schedule. To obtain aniline ink is taken known aniline pigment is also dissolved in water. This solution is not forced to be concentrated, because at that time the ink will dry quickly and is also fragile on paper. With the right concentration, aniline inks are consistent, they easily flow from the pen, do not corrode steel feathers, do not thicken as quickly, and are not covered with mold.

a) Black ink. Dissolve 1 part of nigrosine dissolved in water 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 and dissolve in 90 parts of hot water. After cooling, add 2 gum arabic elements diluted in 10 parts of cold water.

c) Blue ink. To prepare them, they take 5 parts of resorcinol, pour 30 parts of cold water, but after 2 hours 640 parts of hot water are added, in which 20 parts of sugar are also dissolved 1 proportion of crystalline oxalic acid. All together, shake well, leave not to move for several days and filter.

d) Violet ink. For their preparation, take 10 elements of methyl violet, pour 30 parts of cold water, leave for 3-4 hours and add 950 elements of hot water, 10 parts of sugar in the powder and 2 elements of crystalline oxalic acid. Within 2-3 days, the mash is shaken and then filtered.

e) Green ink. To obtain them, take 1 part of water-soluble green aniline dye and also dissolve it in 100-200 parts of boiling water. To get a greener color, you can add some picric acid.

Endless ink

Take 200 elements of shellac, 300 elements of borax, 3000 parts of hot water, dissolve when heated, also add a solution of 100 parts of water nigrosine, 1 elements of picric acid, 3 elements of tannin, 150 parts of ammonia and 75 parts of distilled water.

Hectographic ink

Hectographic ink is a viscous solution of aniline dye, through which you can get, with the help of a hectograph, a lot of prints. The main role here is played by glycerin, which prevents the ink from drying out in a hurry.

Black ink

Red ink

Blue ink

Purple ink

Green ink

  • 10 parts nigrosine,

  • 90 parts of water

  • 10 parts glycerol.

  • 10 pieces of magenta,

  • 10 parts of alcohol

  • 10 parts glycerol,

  • 70 parts of water.

  • 10 parts of blue aniline,

  • 15 parts alcohol

  • 10 parts glycerol,

  • 80 parts water.

  • 10 parts of methyl violet,

  • 5 parts glycerol,

  • 70 parts of water or 10 parts of methyl violet,

  • 8 parts of 20% acetic acid,

  • 4 parts glycerin,

  • 70 parts of water.

  • 10 pieces of indigo carmine,

  • 10 parts of picric acid,

  • 30 parts alcohol,

  • 10 parts glycerol,

  • 80 parts water.

Hectograph production

First of all, you need to take the selected grade of wood glue, having done the following test with it. Take a small piece of glue and immerse it in water at room temperature. If the glue disperses in water, then it is in no way suitable for the manufacture of a hectographic mass; if it turns into a gelatinous mass, then the glue is suitable for making a hectograph.

500 g of such wood glue and 1 kg of technical glycerin are dipped in a newly made tin pot, in which there should not be the slightest presence of fat. At first, glycerin is poured, and is brought to the state at which time the steam will rise from it, by means of gradual heating. Then the joiner's glue is turned into the pot, turned into water by jelly, and the pot is put on the stove again. Heating lasts until the glue dissolves completely in glycerin with gentle stirring so that no air bubbles form. When the heated mass becomes yellow, it is poured into a flat zinc box with well-sealed edges with a height of 2-2.5 cm and left not to move on a flat surface until complete cooling, also the hectograph is ready. If at the time of the mass transfer from the pot to the zinc box, bubbles form on the surface of the mass, then they can be destroyed by holding the burning torch above them. If the hectographic mass is extremely strong and the ink does not stick to it at all, then it is necessary to melt the whole mass again, adding 50-60 g of glycerin. If there is no good wood glue on hand, then 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 the addition of 400 g of talc in the powder.

Recipe for preparing hectographic mass

500 g of gelatin are dissolved in 3 liters of water when heated, at the time of which 6 kg of technical glycerol is added, also 500 g of sulfur-barium salt in the powder.

Stationery ink

  For the preparation of ordinary stationery or school ink by insisting or drawing on cold water take:

  • 3 pieces of ink nuts,

  • 2 pieces of iron sulphate,

  • 2 pieces of gum arabic,

  • 60 parts of water.

The nutlet is pounded into powder and, poured into a glass bottle, is poured with water.

Iron sulfate and gum arabic are dissolved separately in another vessel. The infusion of a nutlet should not move for several days until the water removes all the tannins from it, while the vitriol also gum Arabic completely dissolves within a few hours. Both solutions are poured together, mixed well and also, allowing to stand for a day or a couple, carefully poured to separate the liquid from the precipitate.

Copy Ink

Copy inks are prepared in their composition in the same way as if they are also ordinary inks, only they act more concentrated in the content of the dyeing substance. In addition, sugar is also added glycerin - substances that support moisture. From this, they acquire the property not to soak into the paper and also, when touching an incompletely dried message with a wet tissue paper, to separate a particle of dye substance from themselves. The amount of both substances is best determined on samples.

To test copying ink, you need to put tissue paper on a sheet of thick wax paper (or oilcloths) and wet it with water using a wide brush or sponge. Then cover with running paper also put all this into a thick book and also press hard to extract excess moisture. After this, put the written sheet of paper, cover it with tissue paper and put it all in the book again and press it firmly.

Copy ink for typewriters

Take 3 elements of soap, 12.5 elements of glycerin, 36 parts of water also dissolve when heated. In a friend's vessel, dissolve the required number of any aniline dye in 72 parts of alcohol and mix both liquids.

Paint for typewriters

In a porcelain dish, 100 g of glycerin is heated and 100 g of methyl violet is gradually added to the heated glycerin. After this, the mass is also cooled and gently added to a little water, stirring non-stop. Water is poured to remove grit mass. As soon as the mass becomes a viscous bright liquid, the addition of water is stopped. The tape for the typewriter is pulled through this ink as well between the smooth rollers under strong pressure.

Lithographic ink

Lithographic ink is used by lithographers to make pen tokens directly on flint or on transfer paper.

1. Austrian ink.

For their preparation they take:

  • 600 pieces of yellow wax,

  • 125 pieces of shellac,

  • 75 pieces of fat,

  • 300 pieces of white soap,

  • 100 pieces of mastic,

  • 25 parts of resin

  • 75 parts of Dutch soot.

Finely chopped soap is added to the melted wax and heated until the mass starts to produce an undesirable smell. When cooking you need to be very careful, in the case of ignition, the flame is silenced by the lid. And then, at what time the mass will cool slightly, it is poured into molds.

Lithographic ink, as it is known, is stored in pieces (like Chinese ink), also only to the measure of need, rubbed on a saucer with water to the required thickness. The good quality of this mass is largely due to its sufficient incandescence, so that it can neither be oily nor skinny. Both flaws prevent the transfer of drawings or font on a lithographic stone.

2. English ink

For their preparation they take:

  • 60 pieces of yellow wax,

  • 60 pieces of white soap,

  • 80 pieces of mastic

  • 60 pieces of fat,

  • 120 pieces of shellac,

  • 10 pieces of Venetian turpentine,

  • 11 pieces of Dutch soot.

Mastic and shellac are put in the heated turpentine, then fat, wax and soap are added to the soot. All this is well mixed and pounded. The cooled and slightly hardened mass is laid out on a nasty flint or glass and cut into bars.

Ink for laundry tags

Good ink for labeling linen can be prepared from aniline dyes.

Black ink Take 1 share of nigrosine, soluble in water, 1.5 elements of hydrochloric acid, 22 elements of alcohol. A solution of 7.5 gum arabic elements in 100 parts of cold water is added to this solution.

Red ink. They are prepared similar, but instead of nigrosine they take fuchsin or eosin.

Ink for writing on metals

To write on zinc take:

  • 15 pieces of copper sulfate,

  • 10 parts of potassium chloride,

  • 14 parts of water.

For writing on copper also tin:

  • 25 parts of copper sulfate,

  • 10 pieces of gum arabic,

  • 5 pieces of soot,

  • 10 parts of hydrochloric acid,

  • 24 parts of ammonia,

  • 26 parts of water.

For writing on iron also became:

  • 20 pieces of copper sulfate,

  • 5 parts vinegar,

  • 5 pieces of soot,

  • 10 pieces of gum arabic,

  • 60 parts of water.

For writing by tin:

  • 10 pieces of copper sulfate,

  • 20 parts of water

  • a few drops of hydrochloric acid

  • little gum arabic.

For writing on glass

3 parts of barium sulphate mixed with 1 part of ammonium chloride are also added to the mixture so much sulfuric acid to form a semi-liquid mass. Since such ink corrodes the glass, you can only save them in flasks smeared with paraffin inside.

Stamp paint

Such paint should alienate clean, clear prints also should not dry out on the stamp. Stamp paint is made in different colors, but the most commonly used purple. The easiest way to act it from aniline paints.

We give a proven composition of purple stamp paint:

  • 10 parts of methyl violet,

  • 3 pieces of gum arabic,

  • 1 part glycerol,

  • 2 parts of water.

Gum arabic is dissolved in cold water and also mixed with glycerin, the powder in the powder is put into a flat-bottomed porcelain mortar and also ground with a porcelain pestle, adding little gum arabic with glycerin. For other colors, take the appropriate paint, for black - nigrozin, for red fuchsin, etc.
