To avoid glass marbles leaving scars during the production process, the following measures can be taken:

 1. Control the temperature and humidity of the production environment to ensure that the temperature is not too high or too low, and control the humidity to prevent flaws on the glass surface.

 2. Adjust the production process and adopt better production equipment and processes to reduce the scars on the surface of glass marbles caused by friction. 

3. Workers' skills and experience are also the key to preventing glass marble scars, and it is necessary to conduct training or recruit experienced workers to improve work output and quality of glass marbles.
