Resumo

Sahagún's General History of the Things of New Spain, a Nahuatl text completed in 1555, contains an ethnographic description of cire perdue gold casting. Aboriginal copper casting was not described. However, it is believed that his gold-casting description also constitutes a basically valid description of copper casting. To test this, experiments were undertaken to cast copper bells following Sahagún's description of gold casting and using native materials whenever possible. From the resultant successful casting of several copper bells it is inferred that the above belief is valid.
