teocuitlatl (Mdz70r)
This example of iconography is relevant here for making comparisons with glyphs for gold (teocuitlatl). One of these glyphs appears at the front edge of the bowl as a circle with a quincunx design and painted yellow. This disc is surrounded by red and yellow flames and curling dark smoke. The man making the gold is blowing air through a tube to make the fire hotter for melting the ore. The man wears a (probably white cotten) cape tied at his shoulder and a white loincloth. He sits on a woven reed seat, probably made of petlatl, also given a yellow color by the artist. The gold worker has a tan skin color and the bowl for smelting is a light terracotta, or the same color.
