2543. Black Printing Ink

2543.    Black Printing Ink. Boil 11/2 gallons old clear linseed oil to the consistence of a thick varnish ; whilst hot, add to it, during constant stirring, first 6 pounds powdered resin, and next 13/4 pounds dry brown soap shavings; then mix in it 21/2 ounces indigo blue, 21/2 ounces Paris blue, and 5 pounds best lampblack. After standing for a week it should be ground.

2544. Black or Colored Printing Ink

2544.    Black or Colored Printing Ink. Balsam copaiba, 9 ounces; lampblack, 3 ounces; Paris blue, 11/4 ounces; Indian red, 3/4 ounce; dry resin soap, 3 ounces. These will produce a superior black ink. By employing white soap instead of yellow, and a sufficiency of some coloring pigment instead of the black, blue, and red mixture, a good colored ink will be obtained.

2545. New Ink for Printers

2545.    New Ink for Printers. A new ink for printers has been invented by Professor Artus, and Mr. Fleckstein, a master-printer at Lichtenhain, which ink is said to be a complete success. The composition of it is as follows: Venetian turpentine, 41/2 ounces; fluid soap, 5 ounces; rectified oleine, 2 ounces; burnt soot, 3 ounces; Paris blue (ferrocyanic acid), 1/2 ounce; oxalic acid, 1/4 ounce; distilled water, 1/2 ounce. The mixing process of this new, beautiful, and cheap ink is described as follows: Gradually warm the turpentine and the oleine together; put the soap on a marble plate, and gradually add, continually rubbing, the mixture of turpentine and oleine; when well mixed, add the burnt soot, which must first be well powdered and sifted; then add the Paris blue, dissolved in the oxalic acid, continually rubbing the composition on the stone, the Paris blue and the oxalic acid having been mixed before with water in the above given proportions. A solution of soda in water is sufficient to thoroughly cleanse the type.

2546. Indelible Printing Ink

2546.    Indelible Printing Ink. Mix 1 pound varnish (such as is used for ordinary printing ink), 1 pound black sulphuret of mercury, 1 ounce nitrate of silver, 1 ounce sulphate of iron, 2 table-spoonfuls lampblack. Thoroughly grind together, adding enough turpentine to reduce to the requisite consistency.

2547. Lithographic Ink

2547.     Lithographic Ink. Grind together 8 parts mastich, in tears, and 12 parts shellac; dissolve carefully by heat in 1 part Venice turpentine; after the mixture is taken from the fire, mix in 16 parts wax and 6 parts tallow; then add, by stirring, 6 parts hard tallow soap in shavings, and finally incorporate in the mass 4 parts lampblack. Heat and stir until thoroughly mixed; let it cool a little, and pour it out on tables, and when cold, cut into square rods.

2548. Lithographic Transfer Ink

2548.     Lithographic Transfer Ink. Melt together 8 parts white wax and 2 parts white soap; and, before they become hot enough to take fire, stir in by degrees sufficient lampblack to make the mixture black; then allow the whole to burn for 30 seconds; when the flame is extinguished, add, a little at a time, 2 parts shellac, stirring it in constantly ; put the vessel on the fire again until the mass is kindled, or nearly so. Put out the flame and allow it to cool a little, and then run it into the moulds. Ink thus made will make as fine or coarse lines as are desired, and its traces will remain unchanged for years before being transferred. When suet enters into the composition of lithographic crayons, it does not keep long, and requires immediate transferring to the stone.
