XRF Spectroscopy for Art Examination Metal pewter

This lesson examines pewter, a tin-based alloy widely used from medieval times to the modern era. By comparing three objects—a 17th-century plate, a 19th-century painting support, and a 20th-century vase—students explore how pewter composition evolved as awareness of lead toxicity increased and new metals were introduced to improve performance and safety. https://chsopensource.org/courses/xrf...
