The purpose of this research is to develop new commodities made of the Nachiguro stone powder and useful method for industrial field. We examined several processing methods for the Nachiguro stone powder. When the Nachiguro stone powder was sintered in the atmosphere using the electric furnace, it became the brown sintered object. On the other hand, the Nachiguro stone powder was sintered in the reducing atmosphere that used carbon powder. The sintered object with the same color as the Nachiguro stone was manufactured.
