The Smelting of Sulfide Ores of Copper in Preconquest Peru

Publikováno v: American Antiquity. 25:59-65

Doubts that the Peruvian Indians could smelt copper ores in pre-Columbian times are unjustified, although archaeological evidence for the very effective wind furnaces described by early chroniclers is scanty. Oxide and carbonate ores from shallow dep

Results of a Chemical Examination of Some Specimens of Roman Glaze from Tarsus

Autor: Earle R. Caley

Publikováno v: American Journal of Archaeology. 51:389-393

The proportion of lead in ancient glazes is higher than in modern lead glazes. Probably such high proportions of lead were deliberately used in order to obtain glazes that melted at conveniently low temperatures. The presence of high proportions of l

Gravimetric Determination of Lithium by Precipitation as Trilithium Phosphate

Autor: George A. Simmons, Earle R. Caley

Publikováno v: Analytical Chemistry. 25:1386-1389

Previous attempts to separate and determine lithium quantitatively as phosphate have not been successful. A method is described by which lithium is precipitated as phosphate in 50per thousand 2-propanol with choline phosphate as a reagent. By this me
