Pure copper was found in nature as early as the Stone Age, and knives and chisels repeating forms of stone objects were manufactured of it by beating. The oldest metal tool in Finland so far is a copper groove chisel, which goes back to the end of the Stone Age Huurre The object has been influenced by the early metal culture of Eastern Europe, which had a strong effect on Inner and Northern Finland for two or three millennia. In Lapland, the curved iron daggers of the ancient Sillankorva dwelling place in Kuosku, Savukoski foreshowed the beginning of independent iron manufacture Erä-Esko These daggers, which obviously date from the 5th century BC, were brought from Eastern Russia, from the area of the Ananino culture by the lower course of the River Kama Carpelan Bronze articles were often cast in moulds made of steatite or clay. The desired form could be obtained by using wax running out of the mould while being burnt.

I am employed as a researcher forskare through a Starting Grant from Vetenskapsrådet. My project involves measuring both 14C and stable isotopes δ18O and δ13C on single foraminifera, thus producing palaeoclimate data independent of core depth. Other research interests include geochronologies, palaeomagnetism, strontium isotopes, computer modelling, open access publishing and pizza not Swedish pizza. There is water at the bottom of the ocean. Download CV.
