PURPOSE: A manufacturing method of a stone for the construction usage is provided to use molten slag generated from a steel manufacture and high temperature melting process as a by-product. CONSTITUTION: A manufacturing method of a stone for the construction usage using molten slag comprises the following steps: melting slag by heating to 1,3500~1,500deg C; inserting the molten slag to a preheated mold; and cooling the molten slag 300 deg C per hour inside a furnace. The mold is preheated to 700~1,400deg C. The maximum temperature of the furnace is more than 1,000deg C.
