Production Method for Sheets of Glass with a Diffuse Finish, and Resulting Sheet of Glass

A glass sheet with diffuse finish produced by the process of:

• a) Providing a sheet of glass;
• b) Providing a first immersion of the glass sheet in a first acidic solution for a predetermined time, to remove impurities from the glass;
• c) Rinsing or washing the glass sheet once it has been immersed in the first acidic solution to remove the remaining acidic solution and avoid the formation of undesirable lines and marks in the glass;
• and
• d) Providing a second immersion step to said glass sheet in a second acidic solution for a second predetermined time to generate a diffuse finish on both sides of the glass,
• wherein the process generates in the glass sheet, in at least one side, a diffuse surface comprising:
• a peak-valley roughness (Rt) of about 5.9244 μm;
• an Ra roughness of about 0.7081 μm;
• an RMS roughness of about 0.8764 μm;
• a solar transmission of at least 84%;
• a solar reflectance of about 7.3%;
• a light transmission of about 88.5%;
• and UV transmission of about 64.2%.

• wherein the process includes in the glass sheet, in at least one side, a diffuse surface without attack, comprising:
• one peak-valley roughness (Rt) of about 0.0641 μm;
• an Ra roughness of about 0.0091 μm;
• and an RMS roughness of about 0.0111 μm.
