How to Read the Date from Car Glass?

[OVanessa]

Method to read the date from car glass: It is represented by numbers and dots. The dots can be either before or after the number. The number indicates the year, while the dots represent the month. If the dots are before the number, it indicates the first half of the year. Subtract the number of dots before the number from 7 to get the month in the first half of the year. If the dots are after the number, it indicates the second half of the year. Subtract the number of dots after the number from 13 to get the month in the second half of the year. Car glass is manufactured by heating the glass in a furnace to near its softening temperature, then quickly transferring it to air grids with different cooling intensities for uneven cooling, creating different stresses between the main viewing area and the peripheral areas. Generally, this process produces zone-tempered glass.
