Summary of Cupellation¨Ctemperature Cycle. ¡ª Characteristic temperature cycles in cupellation are shown on Fig. 8, based on measurements taken with a pyrometer ½" above the muffle floor just behind the front row of cupels. The curves apply particularly to buttons from 20 to 25 g in weight and with beads weighing 50 mg or more, cupeled with feathers.
The indicated temperatures are subject to corrections based on the furnace draft, heating and cooling lag, and the pyrometer position.
