Both chemical and heat tempering are used to strengthen glass, but they use different processes and have different advantages and disadvantages.<\/p>\n\n\n\n
Glass is immersed in a potassium salt bath, which causes an exchange of ions on the surface of the glass. This creates a layer of compression on the surface, which makes the glass stronger.

Both processes have their own advantages and disadvantages. It is important to weigh these factors carefully before making a decision.<\/p>\n\n\n\n\n
