ABSTRACT:
A method of restoring damaged portions of paper (Japanese and machine-made) paintings and calligraphic works, which does not require a high degree of skill, retains the original thickness of the work, improves durability after restoration and ensures neutralization of the work and simplification of any further restoration. A raw restoration liquid prepared from paper stock, water and an adhesive such as a liquid extract of Hibisci radix and optionally a colorant is placed in a vat. A target paper work to be restored is laid over a cloth or paper-making sheet which is laid over a filtering sheet-like member fitted into a paper-making frame. The paper-making frame is soaked in the raw restoration liquid so that the fibers contained in the raw restoration liquid are filled into the damaged portions of the paper work. The cloth or paper-making sheet is removed from the paper-making frame while the fibers are dried to the point of dampness. After further drying and removal from the paper-making frame a restored paper work is obtained.
