Ding Feng had to find another method
Chemical dyes have a great harm to the paper
Ding Feng decided to use chestnut shells, rubber bowls, and tea to cook dye
Dyour own dye
In order to cook a paper with similar color to the original cover
He tried more than a dozen times
For the part of the eyebrow of the book "Yonglei Qianfang" that has been acidified
Ding Feng uses vellum In all repair processes, the most important thing is to "slip"
is to use thin strips and paste on the back of the paper to piece together and fix the originally broken book mouth
In order to accurately piece the book leaves as before
Ding Feng decides
First print the leaf frame on the transparent repair board
splicing according to the size of the board frame
Ding Feng discovers
As early as the Qing Dynasty
, a restorator left traces on these two books
by marking the column and supplementing
This ancient colleague completed the information of the original book
so that later generations could also fully understand the original incomplete information
He thought this chance encounter with his predecessors was very interesting:
"It means that I and him (Qing Dynasty restorator)
cooperated to protect this book
but the time period was different."
ml0Ding Feng said that
Ancient Book Repair
is like racing against time

Another batch of books are aging
Always hope that I can be faster
In Nanjing Library Ancient Book Repair Center
and Ding Feng raced against time 12 people
They used professional skills and rigorous attitude
