A manufacturing method for a gravel bone mold is provided to improve convenience of conveying and prevent breakage of bone mold by forming liquid bone powder in a mold shaped like gravel. A manufacturing method for a gravel bone mold comprises a melting step(S1) of melting bone powder with the weight of 100 percentages by mixing ratio of oxygen and gas of 7 to 3 in reductive response atmosphere raised by high temperature of more than 2000 degrees; an additives mixing step(S2) of mixing one of yellow earth or ceramic powder selected as colorant and strength reinforcement to the melted bone powder, to set the liquid bone powder with the weight of 100 percentages against the weight of 10 percentages for 5 minutes by mesh granularity of 400 to 600; and a molding step(S3) of molding the liquid bone powder completed through the additives mixing step in a mold shaped like gravel. |
