错金银工艺
Gold and Silver Inlay
Inlaying gold and silver wire or sheet into bronze surfaces to create exquisite decorative patterns, exploiting differential thermal expansion of metals for a tight fit.

Scientific Principle
Metal plastic deformation: the high ductility of gold and silver allows them to be hammered into grooves. Thermal expansion coefficients: gold/silver > copper, ensuring an even tighter fit upon cooling.
