The invention relates to the technical field of decorative materials, and discloses a stone-like glass mosaic which comprises the following components, by weight: 20-30 parts of glass raw material, 10-15 parts of waste glass, 2-8 parts of borax, 2-5 parts of quartz powder, 2-7 parts of fluorite, 1-3 parts of a dispersing agent, 2-4 parts of zinc oxide and 5-10 parts of a surface treating agent. The surface treating agent is prepared from the following components, by weight: 10-15 parts of nano glass powder, 5-12 parts of pearl powder, 2-8 parts of chinastone powder, 2-5 parts of toughening agent, 1-3 parts of binder and the balance of water. The stone-like glass mosaic prepared by the invention has better wear resistance and hardness, reduces the probability of cracks in the preparation process, also reduces the glass viscosity and surface tension, improves the preparation efficiency, improves the scratch resistance and stain resistance of the surface of the stone-like glass mosaic byusing the cooperation of the surface treating agent, and enhances the quality of the stone-like glass mosaic. The stone-like glass mosaic has the advantages of no dust accumulation on the surface, self-cleaning in rainy days, durability, high novelty, hard texture and stable performance, can maintain the smoothness and glossiness of the surface for a long time, and the decorative effect can be enhanced.
