What can damage the quality of glass?

1. Scratches:Glass is susceptible to scratches from abrasive materials, such as steel wool or sand, which can leave permanent marks on the surface.

2. Etching:Prolonged exposure to certain chemicals, acids, or alkaline solutions can etch or corrode the glass surface, causing it to become dull or appear cloudy.

3. Thermal Shock:Sudden changes in temperature, such as extreme heat followed by rapid cooling, can cause glass to crack or break. This is especially true for thin or unevenly tempered glass.

4. UV Radiation:Over time, exposure to ultraviolet radiation from sunlight can cause glass to become discolored or lose its transparency, particularly if it contains impurities or certain types of coatings.

5. Environmental Factors:Corrosive elements in the atmosphere, such as salt spray, pollutants, or moisture, can gradually deteriorate the quality of glass, especially in coastal or industrial areas.

6. Physical Stress:Excessive pressure, weight, or mechanical stress can cause glass to crack, break, or deform.

7. Cleaning Methods:Improper cleaning methods, such as using harsh abrasives or cleaning solutions that are not compatible with glass, can damage the surface or leave residue that affects its clarity.

8. Manufacturing Defects:Faulty manufacturing processes, such as impurities in the glass composition, bubbles, or inclusions, can compromise the quality and integrity of the glass.
