How to Tell When Car Glass Was Produced?

[VonHarley]

There is a small box at the bottom of the glass with a string of numbers below it, from which you can determine the production date. The numbers represent the production year of the glass. Here is some related information about car glass: 1. Car glass manufacturing: By heating the glass in a furnace to near its softening temperature and then quickly transferring it to air grids with different cooling intensities, uneven cooling is applied to create different stresses between the main viewing area and the peripheral areas of the glass. 2. Winter de-icing methods: Physical de-icing, chemical de-icing, natural de-icing, and maintaining consistent temperatures inside and outside the vehicle.
