Fact 2251 — was inlay wire heated to 550°C
AI-generated with OpenAI image generation. Prompt: “Photorealistic editorial cover for a museum article on precious-metal wire inlay techniques. Macro view of a decorative steel sample with thin gold wire set into shallow ornamental grooves on a dark work surface, no readable text, no weapons, no people, no logos. Museum-quality light reveals fine craft detail, portrait 4:5.”
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.
