Research Abstract

In this study, I researched for making a Dosuriusu. And I made full-dress experiments with strengthen treatment of cultural properties made by clay, on the basis of result researching objects treated by stone strengthen.
I considered the way to strength tests, using needle or digging a hole. And I made choice the way to test using needles. The way i s little damage to objects.
I carried out strength tests three times. I changed blend ratio of WackerOH100 to WackerOM50 considering strength effect and texture keeping.
In the result, I could get strength effect the liquid in the ratio of 1 to l And in comparison color change test, the change was a little.
I made treatment of donated a Dosuriusu as a matter of fact. I got enough strength effect and keeping their texture, and result that the way suits the treatment of Dosuriusu.
