with the metal, and expofing it in the coppcl to a violent 
fire a long while. The impurities of the metal will then 
COP 
be carried ’tfff in drofs, which is called the litharge of gold

COPTER-MINE,/! A place whence copper is dug. 
The principal copper-mine in England is on the ifle of 
Anglefey, which contains a bed of ore forty feet in thick- 
nefs, and is (aid to produce upwards of four thoufand 
tons of copper annually. Confiderable mines of copper 
are alfo found in Spain, France, Norway, Hungary, Swe¬ 
den, &c. The Japan copper is faid to be purer, and to 
have a greater fpecific’ gravity than any ether. A very 
rich copper-mine has been difcovered in the State of 
New Jerfey, in North America ; but the proprietors, 
have not yet fucceeded in working it. This mine was 
difcovered by a perfon who, palling along about three 
o’clock in the morning, obferved a blue flame, about, 
the fize of a man, ilfuing from the earth, which after¬ 
wards foon died away : he marked the place with a flake, 
and when the hill was opened, feveral large lumps of 
virgin copper were found. This promifes to be very 
valuable to the American States.

COPTER AS,/ [ kopperoofe , Dut. couperotfe, Fr. from 
being fuppofed to be found in copper-mines only. ] A 
name given to three forts of vitriol; the green, the bluifh 
green, and the white, which are produced in the mines 
of Germany, Hungary, and other countries. But what 
is commonly fold here for copperas, is. an artificial vitriol, 
made of a kind of ftones found on the fea-fliore in Eflex, 
Hampfhire, and fo weftward, ordinarily called gold ftones 
from their colour. They abound with iron, and are ex- 
pofed to .the weather in beds above ground, and receive 
the rains and dews, which in time breaks and diffolves 
the ftones : the liquor that runs off is pumped into boil¬ 
ers, in which is firft put old iron, which, in boiling, dil'-' 
folves. This factitious copperas, in many refpeCts, agrees 
with the native green vitriol. Chambers. Hill. —It may be 
queftioned, whether, in this operation, the iron or cop¬ 
peras be tranfmuted, from the cognation of copperas with 
copper, and the iron remaining after converfion. Brown. 
In chemiftry, green copperas is called fulphat of iron ; 
blue copperas, lulphat of copper ; and white copperas, 
fulphat of zinc. For their natural and artificial produc¬
