User's instructions solid tusche for lithography.
Tusche disolved in destilled water is called watertusche. Watertusche does not create a homogeneous grey tone, because the tusche does not completely dissolve in the water, but mixes with water as well. Dry, the particles of grease can be seen with the naked eye. The effect of an aquarel. If watertusche is painted on a stone and dries, something shows up like a topographical map, with lots of lines. If the tusche has been dried with warm air, the tone will be slightly more equal.
Normal tap water cannot be used for tusche, because of the lime in the water.
Make a saucer and /or the stick a bit warm with a stove of hairdryer. Take the stick and melt/rub some on the saucer. Pour some destilled water on the saucer. Dissolve the tusche by rubbing it with a finger. Watertusche is not stable. It cannot be kept for a long time. Watertusche is always freshley made.
Making turpentine tusche (of other solvent)
Tusche dissolved in turpentine can give nice equal half tones, in contrary with watertusche. Dissolving in terpentine is the best, but thinner, white spirit and other solvents can be used as well. Preparing is the same as water tusche.
