Descriptions of inlay sometimes give an exact wire-heating temperature, such as 550°C, but the museum source does not verify that figure. The Metropolitan Museum’s technical note describes true inlay this way: grooves are cut into steel, and soft precious-metal wire is hammered into them. That provides a supported account of the basic mechanism, not a recipe with one fixed temperature; the relevant temperature would depend on the metal and process.
