PURPOSE: Provided is a surface treatment method of glass products for lusterless glasses by scratching the surface of glasses with glass powder unlike a conventional etching method using acids. The method improves work safety and productivity, and prevents pollution. CONSTITUTION: The surface treatment method comprises the steps of: loading a bottle(to be treated stuff) on an index support(A1) being rotated by some degrees; elevating the bottle to an effective height, and rotating; spraying glass powder(0.01-0.6mm), mixed with water in a ratio of 1:1, over the surface of the bottle under pressure of 3-5kg/cm2 through nozzles(A2, A3); spraying lubricants obtained by diluting the lubricant solution composed of 30wt.% of surfactant, 20wt.% of fatty acid, 50wt.% of solubilizer with 10-50times(based on the weight of the lubricant solution) of water; washing and unloading the bottle.
