What is indigo dyeing? No. 7 "To dye"

It is very important to manage the dyeing liquor in order to dye better until the end of the life of the indigo that was built. The management method also depends on the dyer, but I will explain it here as well, using the method I learned.

I wrote [Life of indigo], but the dyeing liquor is a treasure trove of microorganisms. Among them, indigo management can be said to be how to prepare an environment where microorganisms such as reducing bacteria, which are useful for dyeing, can live in good health. In other words, it can be said that we are raising creatures.

For management, we perform [stirring], [administration of lye and lime], [temperature control], and [administration of bran] when necessary. Various administrations are like microbial rice. Therefore, if you misunderstand the amount and timing when you need it, the microorganisms will lose their energy, and in the worst case, it may become irreparable, which makes staining impossible. Also, regarding agitation, some microorganisms that dislike oxygen and those who like it live together, and it is necessary for those who like it. If you stir too much, it will be difficult for microorganisms that dislike oxygen to spend time.

Instead of thinking "people-centered", such as managing according to information and dyeing according to the schedule of people, observe indigo closely and what if indigo was a person? Think and face each other. ]
 

It is a summary of the words that the teacher said many times.

By looking into the jars every day, checking the state of the liquid level, measuring the temperature, and dyeing with bare hands at the time of dyeing, you can also feel the current state and make a comprehensive judgment there. Bubbles called [Ainohana] that appear on the surface of the liquid are also barometers for measuring the condition.
With good health management, if I dye an appropriate amount of my jar every other day, it will reach the end of its life in about two and a half months.
 

Ai's life.

It was just built in adolescence full of genki. The color is dark and you can dye a clear color.
It is a middle age after one month. The first powerful color will gradually disappear. Old age from about 2 months ago. It becomes lighter and light blue at the end, and one day it becomes impossible to dye.

If you have a lot of jars, dye them one by one with jars of different ages to make a finish that matches the product.

The end of life means that the pigments contained in indigo have been completely exhausted by the action of microorganisms and have been used up.

The jars that collect on the bottom of the jar of the dyed liquid that has been used up can also be used as fertilizer for the fields.
