Somelors of Gold may be upon powdering of the^^- 
gulus (t\ch iviG0ld) in an Iron-Morter, (for the more cer- 
tain mixture with the Antimony than if it were put in in 
lumps) as alfo by the papers neceffarily ufed* But ic is 
moft probable, that the greateft lofs was by fmall fparks^ 
which continually fly up while the Anttmonj is in a boyling 
hear with the GM\ which is always given it for the better 
facisfaftion concerning the through melting and mixttire* 
Thefe Sparks appear heavy, by their rifing not very high, 
and moft of them falling down again upon the Metal and 
within the Pot ; but many fly over into the fire. 
Thefir Sparks appear to be Gt>W thuss When the Pot 
was covered with a plain fmooth Earthen-cover, fo that 
many of them,uponappu}fe, did ftickto it, and colour'd 
itof a deep-Red 5 Jf. fortU was firft poured on , which 
did not dillolve or fetch off any thing: afccr ^3^. Regm^ 
which did plainly work upon that fubftance, and ran 
off yellow, like a folution of Gold in the fame Wa* 
ter,. 
It is not improbable alfo 5 that fome lofs of Gold may 
be upon the firing of the Jntimony (after the feparation^of 
the Gulden Regulus ) for red^icing it to a Regulus with 
t4rtAr and Nitre ^ which make a vehement conflagration 
with abundant fparkling. 
It hath been fufpededjt hat fomewhat of the Gold may be 
diffipated by the blaft upon the Copels in refining it from 
the Antimony remaining in it. But this is not fo probable ; 
becaufe Gi?/^ hath been melted feveral times with a greater 
proportion of Regulus AnPimmy Simple, than is con* 
xzin^dmthtGolden Regulus, refined from it with the' 
greateft heat and blaft that could be given, without any lofk 
And it is the conftant praflice of fome Refiners , who to 
give their Fin e-G^^W a higher colour for Gildings to put to it 
one third or fourth part of crude Antim^y, or of Regulm of ' 
Antimony^ and with a great heat and ftrong blaft work it off |-
