Making Japanese paper(Washi): its splendor and difficulty

Making Japanese paper(Washi): its splendor and difficulty

1) Fried rice and papermaking

"Paper making (making Japanese paper:和紙)" and "fried rice" dishes are very similar. You may hear a voice saying, "Well, uhhhhhhh?", But it is natural because the similarities are strong.

The rationale goes back to the principle of "paper making". The English word "paper" means "paper" as well, but the Egyptian "papyrus", which is the etymology of the word, cannot be called paper. Papyrus is made by "knitting", "fermenting", and "fusing fibers" of the trunk fibers of gramineous plants. It's a kind of knitting.

On the other hand, "paper" is made by tapping and loosening the skin of the trunk of a plant (especially bast fibers: Jinpisen-i), dispersing it in water, and scooping it up with a net. The manufacturing principle is completely different. It is the originality of the ancient Chinese that the reconstruction work is started after making it uniform in the water. Given the importance of paper as an information medium, this invention will undoubtedly be one of the top three inventions of mankind.



On the other hand, the rice suitable for "fried rice" is "indica rice". This type of rice does not have "stickiness", and the grains do not stick to each other, resulting in a smooth "fried rice". However, this property is not suitable for Japanese "rice", and it is fresh in my memory that indica rice, which was urgently imported during the 1993 rice crop failure, had the lowest evaluation. By the way, "sticky" japonica rice (rice of the strain made in Japan) is not originally suitable for fried rice. But you can make delicious "fried rice". What to do is to put it in a colander and wash it with running water to separate the grains and remove the "stickiness". If you make fried rice after processing it, it will be a wonderfully delicious fried rice. In this case, "stickiness" is a drawback.

By the way, the work just mentioned ... Isn't this similar to the process of dispersing paper fibers in water? -That's right, this is the similarity between "paper making" and "fried rice" that I call. Entrusting everything to the unpredictable movement of water ... this is the greatest "action" of mankind. At this time, we do not discriminate against any material. In Suozi:
荘子)'s words, would it be all-in-one(万物斉同) If the information medium is called Paper, FP, CD, MD, DVD, etc. are also excellent papers.

The Chinese way of thinking pervades life in general. Cheers to their wisdom  !!

A word of the day: Good ancestors do not necessarily mean good offspring. Living in a heritage
If you do that, you'll end up in a merciless China like you are now. In that sense, China is center of the world thought(中華思想) is the biggest enemy of Chinese people.

2) "Paper making" and "Environmental chemistry analysis" Japanese paper special feature

I studied environmental chemistry analysis at the Department of Urban Engineering, Faculty of Engineering, University of Tokyo, Sanitary Engineering (currently called the Environmental Science Course ...). In particular, I worked on the chemical analysis of "water".

The job is to check the concentration of various impurities contained in water (PPM, PPB, PPT, etc.), and in a sense, it is unique that it does not check "water" itself.
There are various tools for examining these impurities, but the basic operation is "titration", which examines impurities by coloring them. For trihalomethanes and dioxins, gas chromatographs (GS), and for heavy metals, atomic absorption (genshikyukou). May also be used. (There will be more advanced equipment now.)

These experiments require step-by-step pretreatment of the sample. If you do not follow the procedure, no data will be output.

By the way, when I abandoned the above world (including environmental chemistry analysis) and lived in the mountains, I noticed that there were mulberry trees (kouzo:楮)in the mountains, and I thought I should do it. Then, as I learned this technology, I felt that it was very similar to environmental chemistry analysis, and I thought, "I am a resident of environmental chemistry analysis."
The fact that proper paper cannot be produced without proper procedures is exactly the same as environmental chemistry analysis.



Of course, my "skills as a papermaker is not as good as a regular papermaker, but I think I can be a spokesperson for them. Currently, Houses doing papermaking all over Japan. Is it less than 50 houses?

A word of the day: I once asked a visiting professor of sanitary engineering if I could make papermaking compulsory, but he refused without any notice. Well, I've been convinced that they haven't made any academic progress in 20 years because of this level.

3) Mental aspects of papermaking

Mr. Tetsuo Tange(哲夫 丹下), a manufacturer of Bi-neutralized paper in Kurashiki City, Okayama Prefecture, is a very famous master of Washi . It is said that many painters and calligraphers have voluntarily made paper of any quality, and the Ganpishi (torinokoshi:鳥の子紙)was previously used as the paper for the Dai-nokyo in Showa era at Todaiji.

When I visited Mr. Tetsuo Tange, He thoughr he could present a book for me, (even including a paper sample) called "Until the Handmade Japanese Paper is Made" (written by Tetsuo Tange himself). I got a thick book. He got liked me.He signed…

"Paper is made with the heart" -Yes, to make paper, you need a mental state that is commensurate with it.

Also, when I asked another papermaker, Mr. Shosaku Tanaka (昭作 田中)of Ogawa Town, Saitama Prefecture, looked at my face (although I somehow wanted to shave the beard that had been stretched until then).

And said a word, "No one who makes paper has a beard." I think this is about right. In my experience. Among the paper-making shops that were introduced in "Quarterly Washi" (Wagami-do: currently closed), there was a person who stretched his beard in Tokushima prefecture.(exception)

By the way, I think that "paper making" is the highest-ranked technology like "swordsmith". This is because one step of the work involves "pushing" things into the water. The state of water in that moment cannot be controlled. There is discontinuity. In the case of pottery, it will be hard to work discontinuously.

And a series of processes including "piercing" that is repeated for each scoop. This repetition should not be considered "purifying the soul"?

A word of the day: I named my poor Japanese paper "Zeus Paper", but I think it is quite good as a printer paper.
