a bellows. From the crucible is a small pipe through which the molten
bismuth runs down into a dipping-pot, and from this cakes are made.
On a dump thrown up from the mines, other people construct a hearth
exposed to the wind, a foot high, three feet wide, and four and a half feet
long. It is held together by four boards, and the whole is thickly coated at
the top with lute. On this hearth they first put small dried sticks of fir wood,
then over them they throw broken ore ; then they lay more wood over it,
and when the wind blows they kindle it. In this manner the bismuth drips
out of the ore, and afterward the ashes of the wood consumed by the fire and
the charcoals are swept away. The drops of bismuth which fall down into
the hearth are congealed by the cold, and they are taken away with the
tongs and thrown into a basket. From the melted bismuth they make
cakes in iron pans.
