_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

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.
