The Lead, Silver and Copper works at Andreasberg. 



The different furnaces, buildings, &;c. composing this establishment, 

 have of late been newly constructed. The arrangement observed 

 is at once simple and convenient, presenting one of the finest models 

 of metallurgical architecture that we have seen. They are situated in 

 a valley about a mile distant from Andreasberg. The arsenical va- 

 pors emitted, are sensible for some distance around, so much so as to 

 occasion nausea at the distance of an hundred yards : what is remark- 

 able, the workmen here employed, suffer less than those at Franken- 

 charner Hutte ; this may be owing to the difference of activity in the 

 cupelling furnaces of the two places. At the latter of these places, 

 there are three or four furnaces in constant operation, and the vapors 

 disseminated in the atmosphere, injure the health and distort the limbs 

 of those employed at this particular operation, to a horrid de- 

 gree. 



The ores that are treated are those mentioned in speaking of the 

 mines. There are subordinate officers situated in different parts of 

 the mine, whose immediate business it is to put aside those portions 

 of ore, as red silver, &;c. extracted in pieces large enough to admit 

 of their being broken and picked, which is the only preparation that 

 these ores undergo previous to their fusion. The galena and the 

 finer part of the ore is washed as at Clausthal, and elsewhere. 



Product and consumption in 1828. — During this year there were 

 smelted, 399^ rosts of schlich, containing after essays 7,528 marks | 

 loths of silver, and 4,783 qts. 5 lbs. of lead which produced 17,910 

 qts. of lead, containing silver which yielded 7,670 marks, 7 loths of 

 unrefined silver, and 7,074 marks, 7 lots of fine silver, 5,054 qts. of 

 litharge, 6,588 qts. of cupel bottoms and 150 qts. of fine copper. 

 The greater portion of the litharge was reduced. 



Total sum of the expenses in 1828, is equal to 27,401 prussiau 

 dollars, 20 groschens, 5 pfenings.
