초록
Recently, Korean food culture has westernized and the consumption of meat has been increased. As a result an enormous amount of disposal of bone is generated and most of them are buried without reutilization. By making bone ash using pig bone, the possibilities of application are examined. The purpose of this study is to establish a manufacturing process of bone ash for the celadon bone body using pig bone. The calcination of the pig bone was mostly to change to the calcium phosphate hydroxide $(Ca_5(PO_4)_3OH)$. The celadon body mixed with pig bone ash 8%, $CaCO_3$ 9%, when fired at $1240^{\circ}C$ under reduction atmosphere, shows 0.1% of water absorption, 65.23 MPa of bending strength.
