The only difference between these three things is .
The silver that remained at the bottom of the cupel was runoff and solidified into blocks. Since lead was also valuable, it was recovered by placing the litharge (lead oxide) remaining from the cupellation process into yet a third furnace and heated to 250 degC and air was blown through it. The lead was runoff and formed into rods.
