Whatfocvcr is meked in the melting Furnace, is let out through an 
liole at the bottom thereof into the pan, which is plac'd in the earth be- 
fore it, and, thus expos'd, it immediately acquires an hard fcum, drofs, 
loaf or cake, which being often taken off from the top, the metal re- 
maining in it becoms purer to which is added Lead, and after fome time 
the melted metal is taken out. Then being again melted in the Driving 
Furnace, the Lead, or what elfe remains mixt with the Silver is driven off 
by the blowing two great bellows, and runs over in the form of Litharge: 
that which firft comes over is theWhite, and that which laft, being longer 
in the fire, is the i??^, not that it is Litharge of Gold, both being dri- 
ven off from the A me metal. 
As Chremnltz, Gold-ore hath Silver in it, fo mott of the Schemm^ 
Silver-ore holds fome Gold which they feparate by melting the Silver, 
then granulating it, and afterwards by diffolving it in Aquafortis^ where- 
by the Gold is lett at the bottom, and is afterwards melted- the J^qua 
fortis is diftilledfrom the Silver, and ferveth again for ufe. 
The Silver then feparated from all its former afTociats, is fent to Chreny 
»/V^, where they coyn it into pieces of a mixt metal ( which is the com- 
iHon Money of the Country,) after this manner : They melt it with a- 
bout the fame quantity of Copper , and run it into Bars, which they beat 
out ; then foftning them in the fire, draw them out to an exad thinnefs 
between two Steel- Wheels; then they cut them out into round pieces 
with an Inftrument like a Shomakers Punk , and then boil them with Tar- 
tar and Salt, (hake them in a Sack with Small- coal and Water, dry them in 
'a Kettle perforated , and afterwards they are drawn between two Wheels, 
in which they receive their Stamp.
