Chemical Hardening vs. Heat Tempering: A Technical Comparison

Tempering Methods

Heat tempering is standard for flat glass, but chemical hardening is often superior for complex 3D shapes like wine glasses and bowls.

Performance Metrics

Chemical hardening provides higher surface compression without the distortion sometimes caused by rapid cooling in heat tempering.
