NOVELTY - A molded product made of wood is put into a vacuum carbonization furnace and heated to 80 degrees C at 0.3-0.4 degrees C/minute. Smoking drying process is carried out by raising the temperature to 200 degrees C at 0.5-0.7 degrees C/minute. Pre-carbonization is carried out by increasing the temperature to 400 degrees C at 0.3-0.4 degrees C/minute. Black charcoal is produced by increasing the temperature to 600 degrees C at 1.7-2.5 degrees C/minute. A fine charcoal is produced by increasing the temperature to 1000 degrees C at 2.8-4.2 degrees C/minute. The furnace is then cooled naturally to 80 degrees C, to obtain egg charcoal.    USE - Manufacture of egg charcoal used for environment construction material and daily-use products e.g. wallpaper, paper, nonwoven material, paint, mortar, coating agent, floor material, and construction panels, for removing noxious and unpleasant smell generated by formaldehyde, ammonia, trimethylamine, methylmercaptan, cigarette smoke, refrigerator, and hydrogen sulfide. Can also be used for air purification, water purification, mineral elution, shielding electromagnetic waves, and humidity adjustment.    ADVANTAGE - The method enables manufacture of egg charcoal which emits large amount of far infrared rays. The egg charcoal has excellent electromagnetic wave shielding property, and contributes to health improvement.    DETAILED DESCRIPTION - A molded product made of wood is put into a vacuum carbonization furnace and heated to 80 degrees C at 0.3-0.4 degrees C/minute, and maintained for 0.5-1 hour. Smoking drying process is carried out by raising the temperature to 200 degrees C at 0.5-0.7 degrees C/minute, and maintaining for 0.5-1 hour. Pre-carbonization is carried out by increasing the temperature to 400 degrees C at 0.3-0.4 degrees C/minute, and maintaining for 0.5-1 hour. Black charcoal is produced by increasing the temperature to 600 degrees C at 1.7-2.5 degrees C/minute, and maintaining for 0.5-1 hour. A fine charcoal is produced by increasing the temperature to 1000 degrees C at 2.8-4.2 degrees C/minutem and maintaining for 0.5-1 hour. The furnace is then cooled naturally to 80 degrees C, to obtain egg charcoal.
