How many methods are there for ink processing?

Traditional ink making method; Ordinary ink is used, and pine trees are drained of gum before logging. Where there is no clean hair of rosin, there is a disease that I can't understand when I use tobacco as ink. Where the pine tree smells, a small hole is made in the root of the tree, and the whole body ointment is warm and gushing out. Where the pine smoke burns, it is cut to a certain size. The bow of a ship is considered to be a round object, like a canopy on a ship, which stretches for thousands of feet. The inside and outside and the interface are all made of paper and mats, and smoke comes out of the small holes at regular intervals. Brick under, flue first. Pay for a few days, rest in the cold, and sweep in. Where pine smoke burns, from the beginning to the end, the fire is set to ventilate the smoke. Close to the first and second section is clear smoke, with good ink as the material. The middle section is mixed tobacco as time ink. If it is only scraped for tobacco and sold for printing, calligraphers will still take it and study it for use. The rest are painters and black chalk. Modern Ink Making The modern ink making method is similar to the traditional ink making method since the Ming and Qing Dynasties, but the cigarettes and drugs used are not as elegant as in the Ming and Qing Dynasties, so the quality of ink is not as good as that in Gu Mo. In order to cater to the purchasing power of the public, we take more raw materials that are easy to buy in the market and use mechanical stirring and kneading. In ancient times, medicinal ink was made for acute diseases in distant places, but its efficacy is unknown to many people today. The record is as follows for common sense only. Raw materials of medicinal ink: rhinoceros horn, antelope horn, bezoar, musk, borneol and pearl, gold foil, toad, bear gall and other precious Chinese medicinal materials. Multicolored ink Multicolored ink has five colors: red, yellow, blue, white and green, as well as white, ochre, magenta and cyan. There are actually more than five colors. This kind of ink is very sticky and suitable for writing and drawing. The most used ink is Zhu Mo, which is used to change or indicate documents. Multicolored ink grinds mineral powder very finely, not black smoke. Adding glue is more than making black ink, and the production method is the same as black ink. ?
