Figures 4 & 5.

Bin Hama's besalèn during a posed smelting session showing the elevated suling and congklok with the bellows boy operating the lamus. Another should be at work (out of frame) pumping air through the subterranean windway. Tentrem's smelting operation. Note the bluish color given off as the heavy-gauge copper wire begins to melt. The small cast disk in the foreground has just been poured and will soon be forged into a bonang kettle.
