THere was taken of Crovjn-Gold (which is, as they call 
it, of 2 2 keratts fine, or 7;; and the Alloy is pare 
Silver i part Coffer , more of the Copper for the molt part) 
to the quantity of 7 peny might diwd 10 grains ^ i.e. 178 
graim. This was melted do\\n with two ounces and two 
drachms of Jntimony^dhom fix times as much as the Gold.) 
And becaufe the Gold was put in plates , for the more cer- 
tain melting and mixture^ the firft regulus of Gold being 
feparated from x\\g Antimony ^ both were powdered apart, 
and the regulus in the Melting-Pot laid upon the fame An-^ 
timony, and fo both melted down again* In both which 
meltings fuch an heat was given,as made all of a clear light, 
even red heat, and boiling* Then the Pot was taken out of 
the fire, and all permitted to feparate, fettle, and cool in 
it. Upon breaking the Pot the of G<>W (being ve» 
ry diftinftinthe botroni, and eafily feparated from the ^;?- 
timony') weighed 6 peny weight and i^grdins ( 16^ grains,) 
N.B. That this way of cooling all in the Pots wasob- 
ferved in all the following Experiments, for the more cer* 
tain feparation and fettlemcnt of the Rtgulm , without ef- 
fufion into the Antimony-Uoxn ( as they call it) or hollow 
Iron-Cone. Which effufion, bpconfoundiog and cooling 
the mixture, may be feme hinderance to a more perfefl re- 
paration. And to E)e fure , in the bottom of the Cone 
there is always a thin cruft of the crude Antimony^ trouble- 
fomto be feparated, without raking off fome part of the 
Kegulus. 
Note alfo. That Bi>rax was ufed in every Pot, for 
prevention of the flicking of the Regulus to the bottom, 
and the Antimony to the fides of it ; fo that both were got- 
ten off clean andin full quantity.
