THE RESEARCHES OF VOTIVE PICTURE TABLETS-THEIR SKILL OF PAINTING AND FITTINNG MATERIALS TO SUPPORT.HOW DOES IT INFLUENCE TO THEIR STABILITY?

本文以736块石碑为研究对象，通过油画、照片、贴布画等绘画方法，将其分为17类。其中胶彩片占80%以上。在这批作品中，我们可以看到两种典型的胶画：批量生产的和定制的。在批量生产的泥板中，我们经常看到支架和框架的简单装配方法，以及图片的粗糙绘制方法，因为它们的结构脆弱，很容易破碎。另一方面，定制的许愿图片泥板是为了保持其支架的稳定性而设计的。它们的特殊装置例如图片的固定方法（Hibukura-hagi，Ari-dome等）和框架结构，使用榫接系统（Hozo-gumi）。胶画的保护受到其原始质量和绘画方法的影响，特别是由粉笔（Gofun）和黄赭石组成的基础。

Almost all votive picture tablets are painted by glue colors, even though since the Meiji period the materials have been deversified.We investigated 736 tablets and classified them into 17 groups by the painting methods such as oil paintings, photographs and pasted rag pictures. The number of glue colored tablets accounts for over 80% of them. In this group two typical glue paintings can be seen : mass-produced ones and custom-made ones.Among mass-produced tablets we frequently find easy fitting methods of supports and frames, and rough painting methods of pictures, they are easily broken because of their fragile structures.On the other hand, custom-made votive picture tablets are devised in order to maintain their supports stability. Their special devices are for example fixing methods of pictures (Hibukura-hagi, Ari-dome and so on) and the frames structure, using mortis and tenon joint systems (Hozo-gumi).Conservation of glue paintings are influenced by their original quality and painting methods, especially the foundation consisted of Chalk (Gofun) and Yellow Ochre.
