Abstract

A study on adhesives for document mending was conducted by blending pulgasari(funori) with wheat starch paste. Pulgasari is usually used for the ‘facing’ process in paper conservation. 7 types of samples, shinpul, gopul, pulgasari blended adhesives were prepared and were applied on Hanji and their effect was assessed and quantified with instrumental methods. Adding pulgasari was shown effective to lower the artifact’s acidity and to increase the document’s flexibility. Adhesive force and viscosity and the degree of greenness and yellowness tended to rise as the ratio of pulgasari blended became higher. In microscopic observation, it showed less void and thicker film as the pulgasari ratio became higher. In the document mending experiment, the higher the ratio of pulgasari, the less stain and less contraction were shown. Blending pulgasari with wheat starch paste can be used as an alternative method to overcome the drawbacks of gopul and shinpul in document mending.
