AbstractIn the Bronze Age, large quantities of copper were extracted by means of a complicated multistage process from the ore chalcopyrite, CuFeS2, largely mined in the Eastern Alps and the Carpathians. The methods used for ore dressing and roasting, slagging of the iron and smelting of the copper matte are now well understood; only the final ...

Few settlement sites, which could provide an insight into these changes, have survived the millennia of intensive agriculture well. Even fewer have been systematically and extensively excavated.

Copper tolerance and segregation distortion in aged Paramecium
Experimental Gerontology, 1978The effect of age on copper tolerance and genetic phenomena in Paramecium has been investigated. Regression analysis of paired observations of log median tolerance limit to copper and age in fissions on four different days has shown that there is no reason to reject the null hypothesis that age has no effect on copper tolerance.
