Provided is a method for surface frosting of glass product, wherein a glass product is first immersed in a pre-treatment solution having a composition including water (H2O) 60-80 wt %, hydrofluoric acid (HF) 10-20 wt %, and nitric acid (HNO3) 10-20 wt % for approximately 5 seconds to remove grease/oil and/or contamination from a surface of the glass product, then immersed in a frosting solution having a composition including nitric acid (HNO3) 15-40 wt %, ammonium hydrofluoride (NH4HF2) 30-60 wt %, hydrofluoric acid (HF) 0-10 wt %, water (H2O) 0-45 wt %, and hydrochloric acid (HCl) 0-1 wt % for approximately 1-5 minutes, and finally rinsed with water. As such, the surface of the glass product so treated forms a surface texture that provides smooth tactility of hand touch and shows an outer appearance of a scale like pattern formed on the surface of the glass product.
