Fills with toned japanese tissue and additional in-painting with acrylics and pastels. Adhered with wheat startch paste:
Seperating, Humidification, Flattening:
These were two objects, adhered together with some sort of water-soluble paste. I seperated them with a methyl cellulose poultice and then passively humidified them to flatten. I also had to do some light mending with japanese tissue and wheat starch paste.
Washing and Lining:
The highly-acidic newsprint were washed in a bath of calcium hydroxide at a pH of about 7.5. They were then lined with methyl cellulose onto tengujo japanese tissue.
This was a basic moriki repair, where I consolidated the corners and used a white eraser to clean dirt of the covers. I toned the moriki with color pastels and used SC6000 to get the leather-like sheen.
Because I was unable to print out a few labels, here are some 'unofficial' photos. I will retake these with the appropriate signage, and hopefully better quality.
Here are a few I have done at U of I.
Before Treatment--This book, from the 1890s, had a complete cover, but needed a complete re-sew of the text block (the original sewing was broken in many places). I guarded every page and re-sewed the text onto three linen chords (the original sewing structure). The boards were then re-attached.
After Treatment--In order to protect the decorative frontispiece, I hinged in a protective, chemically neutral tissue. The spine cover was lined with commerically dyed moriki to strengthen the cover joint.
Before Treatment--This Russian language book was a simple spine treatment, and an example of previous do-it-yourself repair. The sewing remained in tact, so additional support to the text block was added via wheat-starch paste, Japanese tissue and book cloth. Also, potentially damaging tape carriers were removed and new endsheets were attached.
After Treatment--Much of the original spine labeling was kept and applied to the new book cloth. Additionally, commerically manufactured headbands were attached to make the final product look cleaner.
