Note 12 — MEXICAN COPPER TOOLS.
Stephen Salisbury translation
In Molina’s vocabulary a suggestion can be found for what technical purposes tin might have been employed. The word teputzlacopintli is translated with cañuto de estaño, para horadar piedras preciosas (cylinder of tin for perforating precious stones). We may, therefore, presume that the holes bored through the well known green jade trinkets, were drilled by the aid of the mentioned cañuto de estaño.
