Which risk disproportionately increased during late Bronze Age mold-making?

💡 Explanation

Arsenical bronze uses arsenic as a hardening agent; therefore, heating molds risks sublimation and inhalation of highly toxic arsenic fumes, because loss of structural integrity during heating could lead to the element contaminating local air, rather than uniform copper composition.
