    摘要: A method of making synthetic fireplace logs or the like and the logs so produced. Approximately 80-95% by weight of pulverized coal is mixed with 5-20% by weight of dry paraffin to form a heterogeneous mixture. The mixture is fed into a cylindrical log mold and subjected to pressures of approximately 5,000 to 12,000 psi. The logs are then coated with a liquid paraffin.
