while ftrongly. The Lead purified from all Silver, (which 
they call che Soap of Metals) firft put in, raelts down with the 
Silver, and then the Lead and Copper fwim at the top, and run 
over the tejl. Whofe motion the Finer helps with a l^jog Rod 
of Iron drawn along the furfacc of the Silver towards the fore- 
mentioned flit, and often ftirring all the Metal, that theim- 
purer may the better rife : and by continuing this courfe, fe- 
peration is made in two or three hours. 
The grcateft part of the Lead flies away in fmoak. 
If the Lead be gone before ali the Copper, 'cwill rife in 
fmall red firy bubbles ; and then they fay, the Metal Drives^ 
and mufl: add more Lead, The force of che blaft drives the 
higher Metals to the lower fide of thelV;?, and helps its run- 
ing over^ 
When the Silver is fully fined,it looks like rooft pure Qu'ick- 
filver ; and then they take off their fogs and let ir coole. Jn the 
cooling, the Silver will frequently from the middle fpring up 
in fmail Rayes and fall down again. If moifl: Silver be puc 
into ihat which is melted, 'cwill fpring into the fire. 
A good Tejl will ferve twoor three firings. 
So foon as the Silver will hold together, they take it out of 
theTe/?, and beat it on an Anvile into a round figure, for the 
Melting Pot : which being fet in a Wind-Furnace,rurrounded 
withCaal, and covered with an Iron Cap, that no Charcoal 
fall into it, is then melted. 
If any Drofs or filth be in the Melting-Por, they throw in 
fomeTincal, which gathers the drofs together that it may be 
feparated from if. 
ThefeMeltmg-Pots are never burned, but only dryed, and 
willlafl:a whole dav, if they be not fufFered to cool : but if 
they once cool, they infallibly crack. 
NEXT IS tte JLMOND'FURNACE or Sweep. Here 
are ftparared ail forts of Metals froai Cinders, pares of iMe' -
