Pre-Seima Turbino : 夏商 청동기

[星の王子樣(116.47)]

당시, 대량의 주석(Sn) 광산이 분포해 있던 이르티시 유역의 알타이와 바이칼~내몽골 동남부 사이를

왕래했을 집단의 주류 하플로는 N 타입이었을 것 같다.

당시, 유목화된 N이 청동기와 제련법을 갖고 오르도스~산서성 북부까지 왔을 것 같다.

투르크나 흉노와 살짝 겹치거나, 그 이전의 이야기가 될 듯.

Initially, bronze was made out of copper and arsenic, forming arsenic bronze, or from naturally or artificially mixed ores of copper and arsenic, with the earliest artifacts so far known coming from the Iranian plateau in the 5th millennium BC. It was only later that tin was used, becoming the major non-copper ingredient of bronze in the late 3rd millennium BC.

Tin bronze was superior to arsenic bronze in that the alloying process could be more easily controlled, and the resulting alloy was stronger and easier to cast. Also, unlike arsenic, metallic tin and fumes from tin refining are not toxic.

The earliest tin-alloy bronze dates to 4500 BC in a Vinča culture site in Pločnik (Serbia). Other early examples date to the late 4th millennium BC
