Clavijero believed that the extreme toughness of hard copper was the result of a special tempering process and Guillermo Dupaix, who was of the same opinion, travelled to then-New Spain in 1806 and found metal pieces in Oaxaca which he referred to as “red copper chisels”.

Clavijero creía que la extrema tenacidad de este material se debía a un temple especial, y lo mismo creyó Guillermo Dupaix, quien en 1806 viajó a la entonces Nueva España, refiriéndose a unas piezas metálicas que halló en Oaxaca como “cinceles de cobre rojos” .
