=Ink.= _Syn._ ATRAMENTUM, L. Coloured liquid employed for writing with a pen. Ink is made of various substances and colours; but at present we shall confine our attention to the tanno-gallic compounds, to which the term, when standing alone, is almost exclusively applied.
_Prep._ 1. Aleppo galls (well bruised), 4 oz.; clean soft water, 1 quart; macerate in a clean corked bottle for 10 days or a fortnight, or even longer, with frequent agitation, then add of gum Arabic (dissolved in a wine-glassful of water), 1-1/4 oz.; lump sugar, 1/2 oz.; mix well, and afterwards further add of sulphate of iron (green copperas, crushed small), 1-1/2 oz.; agitate occasionally for 2 or 3 days, when the ink may be decanted for use, but is better if the whole is left to digest together for 2 or 3 weeks. When time is an object, the whole of the ingredients may at once be put into a bottle, and the latter agitated daily until the ink is made; and boiling water instead of cold water may be employed. _Product._ 1 quart of excellent ink, writing pale at first, but soon turning intensely black.
2. Aleppo galls (bruised), 12 lbs.; soft water, 6 galls.; boil in a copper vessel for 1 hour, adding more water to make up for the portion lost by evaporation; strain, and again boil the galls with water, 4 galls.; for 1/2 an hour; strain off the liquor, and boil a third time with water, 2-1/2 galls., and strain; mix the several liquors, and while still hot, add of green copperas (coarsely powdered), 4-1/2 lbs.; gum arabic (bruised small), 4 lbs.; agitate until dissolved, and after defecation strain through a hair sieve, and keep it in a bunged-up cask for use. _Product._ 12 galls.; very fine and durable.
3. Aleppo galls (bruised), 14 lbs.; gum, 5 lbs; put them in a small cask, and add of boiling soft water, 15 galls.; allow the whole to macerate, with frequent agitation, for a fortnight, then further add of green copperas, 5 lbs., (dissolved in) water, 7 pints; again mix well, and agitate the whole once daily for 2 or 3 weeks. _Prod._ Fully 15 galls. Resembles No. 1.
4. Galls (bruised), 9 lbs.; logwood chips (best Campeachy), 3 lbs.; boil as in No. 2; to the strained mixed liquors, add of gum arabic and green copperas, of each (bruised small), 4 lbs.; simmer or digest until dissolved, and at once strain through a hair sieve into the store-cask or jars. _Prod._ 16-1/2 galls. Excellent, but inferior to the preceding.
5. Galls (bruised), 2 lbs.; logwood chips, green copperas, and gum, of each 1 lb.; water, 7 galls.; boil 2 hours, and strain. _Prod._ 5 galls. A superior ink for retail.
6. Galls (bruised), 1 lb.; logwood, 2 lbs.; gum (common), 1 lb.; green copperas, 3/4 lb.; water, 8 galls.; proceed as last. _Prod._ 6 galls. Common, but fit for all ordinary purposes.
The following formulæ are for some of the advertised inks, or are those recommended by the authorities whose names are attached to them:--
7. (ANTI-CORROSIVE.) Same as 'Asiatic ink.'
8. (ASIATIC.) Galls, 4 lbs.; logwood, 2 lbs.; pomegranate peel, 2 lb.; soft water, 5 galls; boil as in No. 2, then add to the strained and decanted liquor, when cold, of gum Arabic, 1 lb.; lump sugar or sugar candy, 1/4 lb.; dissolved in water, 3 pints. _Product._ 4-1/2 galls. Writes pale, but flows well from the pen, and soon gets black.
9. (Brande.) Galls, 6 oz.; green copperas and gum Arabic, of each 4 oz.; soft water, 3 quarts; by decoction.
10. (Chaptal.) As No. 4 (nearly), adding sulphate of copper, 1/2 lb. Full coloured, but less durable and anticorrosive than the preceding.
11. (Desormeaux.) Galls, 1 lb.; logwood chips, 4 oz.; water, 6 quarts; boil 1 hour, strain 5 quarts, add of sulphate of iron (calcined to whiteness), 4 oz.; brown sugar, 3 oz.; gum, 6 oz.; acetate of copper, 1/4 oz.; agitate twice a day for a fortnight, then decant the clear, bottle, cork up for use. Writes a full black, and otherwise resembles No. 10.
12. (Elsner.) Galls (powdered), 42 oz.; gum Senegal (powdered), 15 oz.; distilled or rain water, 18 quarts; sulphate of iron (free from copper), 18 oz.; liquor of ammonia, 3 dr.; spirit of wine, 24 oz.; mix these ingredients in an open vessel, stirring frequently until the ink attains the desired blackness. This formula is said to give a deep black, neutral ink that does not corrode steel pens.
13. (EXCHEQUER.) Galls (bruised), 40 lbs. (say 4 parts); gum, 10 lbs. (say one part); green sulphate of iron, 9 lbs. (say one part); soft water, 45 galls., (say 45 parts); macerate for 3 weeks, employing frequent agitation. "This ink will endure for centuries."
14. (Guibourt.) Galls (in powder), 50 parts; hot water, 800 parts; digest 24 hours, strain, and add of green sulphate of iron and gum Arabic, of each 25 parts; when dissolved, add the following solution and mix well:--Sal ammoniac, 8 parts; gum, 2 parts; oil of lavender, 1 part; boiling water, 16 parts. Said to be indelible.
15. (JAPAN.) This is a black and glossy kind of ink, which may be prepared from either of the above receipts by calcining the copperas until white or yellow, or by sprinkling it (in powder) with a little nitric acid before adding it to the decoction (preferably the former), by which the ink is rendered of a full black as soon as made. The glossiness is given by using more gum. It flows less easily from the pen than other inks, and is less durable than ink that writes paler and afterwards turns black. It is unfitted for steel pens.
16. (Lewis.) Bruised galls, 3 lb.; gum and sulphate of iron, of each 1 lb.; vinegar, 1 gall.; water, 9 quarts; macerate with frequent agitation for 14 days. To produce 3 galls. Fine quality, but apt to act on steel pens.
17. (PREROGATIVE COURT.) Galls, 1 lb.; gum Arabic, 6 oz.; alum, 2 oz.; green vitriol, 7 oz.; kino, 3 oz.; logwood raspings, 4 oz.; soft water, 1 gall.; macerate at last. Said to write well on parchment.
18. (Ribaucourt.) Galls, 1 lb.; logwood chips and sulphate of iron, of each 1/2 lb.; gum 6 oz.; sulphate of copper and sugar candy, of each, 1 oz.; boil the first two in soft water, 2-1/2 galls., to one half, then add the other ingredients. Full coloured, but somewhat corrosive, as No. 10.
19. (Dr Ure.) Galls, 12 lbs.; green copperas and gum Senegal, of each 5 lbs.; as No. 2 (nearly). To produce 12 galls.
20. (Dr Wollaston.) Galls, 1 oz.; sulphate of iron, 3 dr.; gum, 1/4 oz.; cold water 1/2 pint; put into a bottle and shaken together every day for a fortnight or longer. A good durable ink, which will bear diluting.
21. (_Pharmaceutische Zeitung._) By adding ferrocyanide of potassium to ordinary ink, an indelible writing ink may be obtained. The removal of such an ink by an acid would result in the production of Prussian blue.
_General Commentary._ According to the most accurate experiments on the preparation of black ink, it appears that the quantity of sulphate of iron should not exceed 1/3rd part of that of the galls, by which an excess of astringent vegetable matter, which is necessary for the durability of the colour, is preserved in the liquid. Gum, by shielding the writing from the action of the air, tends to preserve the colour; but if much is employed, the ink flows languidly from quill pens, and scarcely at all from steel pens. The latter require a very limpid ink. The addition of sugar (especially of moist sugar) increases the flowing property of the liquid, but makes it dry more slowly, and frequently to pass into an acetous state, in which condition it acts injuriously on the pen. Vinegar, for a like reason, is not calculated for the menstruum, as it rapidly softens quill or horn, and corrodes iron and steel.
To ensure the permanency of the colour of the tanno-gallic inks, the best Aleppo or blue nut-galls must alone be used. No second or inferior quality should be employed. A contrary practice, often adopted for the sake of economy, is nearly always followed by unpleasant results and often by considerable loss.
The only improvement of importance which has been made in the manufacture of writing ink from the common materials, during the last few years, is the practice of first roasting the gall-nuts, which is now adopted by a few of the houses most celebrated for their COPYING INK. In this way a portion of pyrogallic acid is formed, which is very soluble in water, and strikes an intense bluish-black colour with the protosulphate or green sulphate of iron. From galls so treated an ink may be made to write black at once. Care must, however, be taken to avoid any loss of materials by volatilisation.
To prevent any tendency to mouldiness in ink, a few bruised cloves, or a little oil of cloves, or, still better, a few drops of creasote (carbolic acid) may be added. The last two should be previously dissolved in a small quantity of strong vinegar, or rectified spirit. With the same intention some of the large makers allow the ink to become covered with a skin of 'mould' in the cask, to render it less liable to undergo the same change when subsequently bottled. Formerly the practice was to add a little spirit for the same purpose.
Sumach, logwood, and oak-bark are frequently substituted for galls in the preparation of common ink. When such is the case, only about 1/6 or 1/7th of their weight of copperas should be employed. Inks so made possess little durability.
The very general use of steel pens of late years has caused a corresponding demand for easy-flowing inks, many of which are now vended under the titles of WRITING-FLUIDS, STEEL-PEN INK, ANTICORROSIVE INK, &c. The greater number of these are prepared from galls in the preceding manner; but a less quantity of gum is employed, and greater attention is paid than heretofore to avoid every source of 'greasiness' among which smoke and dirty utensils are, perhaps, the principal. The blue 'writing fluids,' which either maintain their colour or turn black by exposure to the air, are, in general, prepared from ferrocyanide of potassium, or from indigo, and are fully noticed in another place. COPYING INK, another variety of ink of recent introduction, is characterised by its suitableness to metallic pens, and by furnishing a transcript by means of the 'copying press' or 'copying machine.' (See _below_.)
The inks prepared by the first four of the above formulæ are very durable and limpid, and will bear dilution with nearly an equal bulk of water, and still be superior in quality to the ordinary inks of the shops. See GALLS, IRON, WRITING FLUID, and _below_.
=Ink, Blue and Blue black.= See WRITING FLUID.
=Ink, Brown.= 1. A strong decoction of catechu; the shade may be varied by the cautious addition of a little weak solution of bichromate of potash.
2. A strong decoction of logwood, with a very little bichromate of potash.
=Ink, Carbon.= Dissolve real Indian ink in common black ink, or add a small quantity of lampblack previously heated to redness, and ground perfectly smooth, with a small portion of the ink.
=Ink, Carmine.= Heat a scruple of carmine with 3 oz. of water of ammonia for some minutes, a little below boiling, and add 15 to 20 gr. of gum. (The inkstand must be kept well closed.)
=Ink, Chrome.= See GREEN INK and WRITING FLUID.
=Ink, Coloured.= Inks of various colours may be made from a strong decoction of the ingredients used in dyeing, mixed with a little alum or other substance used as a mordant, and gum Arabic. Any of the ordinary water-colour cakes employed in drawing, diffused through water, may also be used as coloured ink. See BROWN, GREEN, and RED inks, &c.
INK, COPYING. This is usually prepared by adding a little sugar or other saccharine matter to ordinary black ink, which for this purpose should be very rich in colour, and preferably made from galls prepared by heat, as noticed above. Writing executed with this ink may be copied within the space of 5 or 6 hours, by passing it through a press (COPYING PRESS) in contact with thin unsized paper (BANK-POST), slightly damped, enclosed between two sheets of thick oiled or waxed paper, when a reversed transcript will be obtained, which will read in proper order when the back of the copy is turned upwards. In the absence of a press a copy may be taken, when the ink is good and the writing very recent, by rolling the sheets, dully arranged on a ruler, over the surface of a flat smooth table, employing as much force as possible, and avoiding any slipping or crumbling of the paper. Another method is to pass a warm flat-iron over the paper laid upon the writing. The following proportions are employed:
1. Sugar candy or lump sugar, 1 oz.; or treacle or moist sugar, 1-1/4 oz.; rich black ink, 1-1/2 pint; dissolve.
2. Malt wort, 1 pint; evaporate it to the consistence of a syrup, and then dissolve it in good black ink, 1-1/4 pint.
3. Solazza juice, 2 oz.; mild ale, 1/2 pint; dissolve, strain, and triturate with lampblack (previously heated to dull redness it a covered vessel), 1/4 oz.; when the mixture is complete, add of strong black ink, 1-1/2 pint, mix well, and in 2 or 3 hours decant the clear.
_Obs._ After making the above mixtures, they must be tried with a common steel pen, and if they do not flow freely, some more unprepared ink should be added until they are found to do so.
=Ink, Gold.= From gold in the state of a impalpable powder, ground up with a little gum water. The brilliancy of the writing performed with this ink is considerable, and may be increased by burnishing.
=Ink, Green.= 1. From sap green dissolved in very weak alum water.
2. A strong solution of binacetate of copper in water, or of verdigris in vinegar.
3. (Klaproth.) Verdigris, 2 oz.; cream of tartar, 1 oz.; water, 1/2 pint; boil to one half, and filter.
4. (Winckley.) Bichromate of potassa, 3 parts; hot water, 8 parts; dissolve, add of rectified spirits, 4 parts, mix, and further add of sulphuric acid, q. s. to liberate the chromic acid, avoiding excess; next evaporate to one half, dilute with water, filter, and add to the filtrate rectified spirit, 4 parts together with 3 or 4 drops of sulphuric acid (if required), to precipitate any remaining potash salt; lastly, decant and preserve the liquid until it assumes a rich green colour.
5. A solution of recently precipitated hydrated oxide of chromium in liquor of ammonia, diluted with distilled water, q. s. A magnificent dark-green liquid, perfectly anti-corrosive.
=Ink, Horticultural.= _Prep._ Chloride of platinum, 1/4 oz.; soft water, 1 pint; dissolve, and preserve it in glass. Used with a clean quill to write on zinc labels. It almost immediately turns black, and cannot be removed by washing. The addition of gum and lampblack, as recommended in certain books, is unnecessary, and even prejudicial to the quality of the ink.
2. Verdigris and sal ammoniac, of each 1/2 oz.; levigated lampblack, 1/2 oz.; common vinegar, 1/4 pint; mix thoroughly. Used as the last, for either zinc, iron, or steel.
3. Blue vitriol, 1 oz.; sal ammoniac, 1/2 oz. (both in powder); vinegar, 1/4 pint; dissolve. A little lampblack, or vermilion, may be added, but it is not necessary. As No. 1; for iron, tin, or steel plate. Some of the preparations described below under '_Incorrodible ink_' are also used by gardeners and nurserymen.
=Ink, Incorro''dible.= This name has been given to several preparations of a resinous character, capable of resisting the action of damp and acids.
_Prep._ 1. Boiled linseed oil, ground with lampblack and Prussian blue, of each q. s. to impart a deep black colour. It may be thinned with oil of turpentine.
2. Good copal or amber varnish, coloured with either plumbago or vermilion.
3. Trinidad asphaltum (genuine), 1 part; oil of turpentine, 4 parts; colour (as last) q. s.
4. (Close.) Cobalt (in powder), 25 gr.; oil of lavender, 200 gr.; dissolve by a gentle heat, and add of lampblack, 3 gr.; indigo 1 gr. (both in impalpable powder); or vermilion, q. s.
5. (Hausmann.) As No. 3 (nearly). Resists the action of iodine, chlorine, alkalies, and acids.
6. (Sheldrake.) Asphaltum dissolved in amber varnish and oil of turpentine, and coloured with lampblack.
Coarsely powdered anacardium nuts (the fruit of the _Anacardium orientale_) are macerated in a well-closed bottle with petroleum ether, for some time. Upon allowing the latter to evaporate spontaneously, a syrupy residue is left, and this, when applied to linen or cotton cloth, imparts to them a brownish-yellow colour, which instantly changes to a deep black on the addition of ammonia or lime water. (Böttger.)
_Obs._ The above are also frequently called 'indelible' or 'indestructible inks.' They are employed for writing labels on bottles containing strong acids and alkaline solutions. The last five are very permanent, and are capable of resisting the action of iodine, chlorine, alkaline lyes, and acids, together with all the operations of dyeing and bleaching, and at once offer a cheap and an excellent material for marking linen, &c., as they cannot be dissolved off by any menstrua that will not destroy the fabric. They must be employed with stamps, types, or stencil plates, by which greater neatness will be secured than can be obtained with either a brush or pen. See HORTICULTURAL INK, INDELIBLE INK, &c.
=Ink, Indel'ible.= _Syn._ INDESTRUCTIBLE INK. _Prep._ 1. Lampblack (previously heated to dull redness in a covered vessel), 1/4 oz.; triturate with good black ink (gradually added), 1 pint. Resists chlorine, weak acids, and weak alkaline lyes, in the cold.
2. (Bezanger.) Lampblack ground in a lye of caustic soda, combined with a mixture of gelatin and caustic soda. Said to be indelible, and to resemble genuine China ink.
