PURPOSE: A manufacturing method of light weight artificial marble excellent in color stability, like no discoloration, is provided to express various colors and shorten the process by using calcined quartz powder and calcined natural stone chips, dolomite. The artificial marble is used for sanitation fixture, bottom material and sink board. CONSTITUTION: The method comprises the steps of: preparing quartz(SiO2) powder calcined at 1100-1300deg.C for preventing discoloration, Al(OH)3 as a filler and a resin or calcined quartz powder, dolomite chips calcined at 600-1100deg.C for light weight and a resin, where the hardener is added 1-1.5times as much as the resin and the promoter is added 0.5-1.2times as much as resin; mixing them by ultrasonic wave; degassing it; filling a mold with the mixture and vibration-mixing it; hardening it by adding at 60-65deg.C for 30-40min.; and demolding it.
