De Re Metallica, Translated from the First Latin Edition of 1556 by Georg Agricola
Book IX. The German term in the Glossary for _panes ex pyrite_ is
_stein_, the same as the modern German for matte. Orpiment and realgar
are the yellow and red arsenical sulphides. The _cadmia_ was no doubt
the cobalt-arsenic minerals (see note on p. 112). The "solidified
juices" were generally anything that could be expelled short of
smelting, _i.e._, roasted off or leached out, as shown in note 4, p. 1;
they embrace the sulphates, salts, sulphur, bitumen, and arsenical
sulphides, etc. For further information on leaching out the sulphates,
alum, etc., see note 10, p. 564.
