Abstract
A colored refractory material for lining an instrument/apparatus used at a high temperature is formed by mixing a powder of a raw material containing ceramics with a coloring agent and kneading with a liquid using a binder. The refractory material is put in lining for a portion being in contact with a high temperature molten substance or being exposed to a high temperature atmosphere, and is dried by heating while adjusting a temperature and a heating time on the basis of color change on the surface of the refractory material.
