Origin
Legend has it that during the Zhou Dynasty, there was a man named Xing Yi who was good at poetry and painting. One day, when Xing Yi was washing his hands in the river, he saw a dark thing floating on the river. He picked it up out of curiosity and saw that it was a piece of unburned pine charcoal, so he threw it into the river. . Xing Yi suddenly found that his freshly washed hands were stained with a dark color. "Since pine charcoal can be used for dyeing, can it be used for writing?" Xing Yi couldn't help but wonder. He quickly chased downstream and fished out the piece of pine charcoal again.
Xing Yi took the pine charcoal home, crushed it with bricks, and ground it into powder.
"What are you doing? Eat quickly!" His wife Wang said, bringing a bowl of wheat porridge to Xing Yi.
Xing Yi glanced at the wheat porridge, and with an idea, he picked up the black powder and sprinkled it into the bowl of wheat porridge.
"Oh, you are crazy!" Wang said in surprise.
Xing Yi smiled and did not answer. He picked up the chopsticks, dipped them into the bowl a few times, and scratched the wall a few times. Black marks appeared on the wall.
"Haha, I found the materials to write poems and paintings!" Xing Yi exclaimed happily. From then on, Xing Yi used liquid mixed with pine charcoal powder to write poems and paintings. This liquid was the most primitive ink in our country.

The main raw materials of ink are carbon smoke, rubber, additives and solutions, etc., which are generally processed by machinery. There are many types of soot, including various minerals, plants and animal raw materials that are produced by combustion or thermal decomposition. In addition to animal glue, glue is mostly used in vegetable glue (gum arabic) or various synthetic glues such as acrylic glue, polyol resin, etc. Additives include various stabilizers, penetrants, wetting agents, preservatives, fragrances, etc.

The main components of ink are bone glue and carbon black. Generally, when ink stains fabrics, it is attached to the surface of the fabric and is easily soluble in water, so water starch slurry can be used to remove stains. First prepare an appropriate amount of glutinous rice or white rice, apply the rice to the contaminated area of ??the fabric, and rub it gently and evenly, so that the starch stickiness in the rice can bring out the carbon black that has penetrated into the fabric fibers. , and then wash the clothes with detergent. Finally rinse with clean water.
Edit this paragraph about squid ink
The composition of squid ink is completely different from the black ink commonly used for writing. The melanin contained in the "ink" produced by squid is a protein that will be broken down over time.
Sepia ink was originally used to stop bleeding. Since the 1990s, sepia ink has attracted widespread attention due to its high anti-tumor activity and outstanding role in enhancing the body's immunity, and has become the main raw material of Japanese health foods. Golden squid has the characteristics of high nutrition, short life cycle (usually one year), fast growth and wide distribution. It is a promising marine aquaculture species and is also the largest and most potentially valuable protein resource in the ocean. For the comprehensive development of golden squid ink health foods and medicines, the following nutrients are provided. The main nutrients of golden squid ink are: 83.93% moisture, 9.18% crude protein, and 0.97% fat; the total amino acid content is 70 mg/g, and the total essential amino acid content is 29.5 mg/g, including 9.7 aspartic acid and 9.7 threonine. 4.7, serine 3, glutamic acid 7.7, glycine 4, alanine 8.6, valine 4.2, isoleucine 5, leucine 8.7, arginine 5.2, phenylalanine 2.8mg/g, etc.** *17 species; it contains trace elements potassium 3756.7, sodium 15832, manganese 20586.3, calcium 19901.7, iron 12.15, copper 7.91, zinc 9.1mg/Kg. Sepia ink is of great interest in the food industry, with breads, spaghetti, Filipino sauces, and a wide variety of Japanese squid ink foods being coveted.
