DESCRIPTION:

This is a full style case binding with tight back and flat spine. It is fully covered in light green cloth and the cover boards are straw board. The cloth covering is lined up with a layer of yellowish coloured paper. There is another layer lining of white paper on the spine. The caps are pulled over the top of the bookblock. A folded stuck-on endband can be seen at the tail. Both the spine and right cover have red title on top of them. 

 

The textblock is sewn on two recessed cord supports, with two kettle stitches at head and tail.  The paper is yellowish coloured  and machine-made. The edges of the texbloock are trimmed. The tipped-on, single bifolio endleaves of machine-made paper are white coloured. The spine of the textblock is lined up with an open-wave cloth. There are several tipped -on plates of single leaf through the textblock. There is printer’s ink through the text, with the colour of black, blue and red.

 

CONDITION:

The binding is in poor condition overall with both the left and right boards detached. The spine covering has discolouration along it and becomes yellowish. It has losses and the lining material comes off. 

 

The textblock is in poor condition overall with sewing getting loose, brittle paper and insect damages. The paper is very fragile and has discolouration throughout the textblock, especially at the foredge side. There are several tears, losses between the pages.  Both the left and right endleaves are separated on the fold and have insect damages. The sewing supports are fragile and the thread is broken at the first few sections, so the first few sections are split and have some tears on the spine edge.

 

TREATMENT PERFORMED:

(1) Cleaning and Resizing:  

      Detached the whole book and laid the leaves separately into water with the temperature of    

      30℃ for half an hour. Changed the water every 10 minutes to help washing out more

      discolouration. And then put the leaves into 0.25% of Methylcellulose solution for 10 minutes

      for sizing. Then dried them out. 

 

(2) Paper treatment: 

     Chose some Chinese tissue which has similar colour to the textblock. Used the mixer and water

     to blend the paper into paper pulp. Add a small amount of methyle cellulose into the  pulp to

     make  them disperse evenly. Took two dishcloths with good quality of water imbibition and put

     them on the table. And then put the bamboo screen beyond it, which was usually used for

     making hand-made paper. Then used a dropper to sip the paper pulp and apply them to the

     tears, missing areas and fragile edges. After the pulp was finished, left the paper unpressed

     until it was half dry. Then pressed it and changed blotter frequently until the paper totally get

     dry. Rebuilt up the section by original order, then resewn the textblock by using the original    

     holes and new sewing supports.  

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

(4) Cover treatment: 

     Separated the textile and cover boards, and then separated the boards and the endpapers.

     Replaced the original boards by using new archival boards. Cut a piece of aerocotton which is    

     close in thickness to the original one and then toned it light green with acrylic paint. When dry,

     used the textile to repair and reinforce the spine of the cloth covering. Lined up the covering

     with a new layer of Chinese paper. 

 

 (4) Reattachment: 

      Used a layer of Chinese paper to line the spine of the textblock. Cut a new piece of archival

      cloth which is 5mm shorter than the height of the textblock and about 40mm wider than the

      spine of the book block. Applied a layer of wheat starch paste to the spine area and then

      centered the cloth on the spine. A hollow spine of kraft paper was made and applied on the             top of the archival cloth. When finished, reattached the case.
