Thaum ntxov li 3000 BC, cov neeg pib tsim thiab siv tooj. Txawm li cas los xij, Tin Bronze cov khoom ua los ntawm tooj liab smelting yog muag dhau, khoov yooj yim, Tin Bronze thiab sai sai ua npub. Tom qab ntawd nws tau tshawb pom tias cov tin tau sib xyaw rau hauv tooj liab los ua tooj liab-tin alloy-bronze. Cov khoom siv tooj dag tau yooj yim dua rau smelt thiab ua dua li cov tooj liab ntshiab, Tin Bronze thiab nyuaj dua li tooj liab ntshiab (yog tias tus nqi hardness ntawm tin tau tsim rau 5, ces lub hardness ntawm tooj liab yog 30, Tin Bronze thiab lub hardness ntawm tooj yog 100 ~ 150), Tin Bronze uas yog hu ua qhov no hauv keeb kwm Lub sijhawm ntawd yog Hnub Nyoog Bronze.
Phau ntawv" Zhou Li · Dongguan · Guren" thaum lub sijhawm Warring States Lub Sijhawm nyob hauv Suav teb piav qhia txog kev nplua tooj tooj, qhia txog cov feem sib txawv ntawm tooj liab thiab tin siv ntau yam tooj dag:" Kub muaj rau (ntsiab lus). Rau lub ntsiab lus ntawm kub. (Tooj liab) Thiab cov yajthem yog ib qho, Tin Bronze nws yog kev sib raug zoo ntawm lub tswb nrov thiab qhov txav chaw; lub tsib yog kub thiab cov tin yog cov, Tin Bronze yog tus taus; lub quarter yog kub thiab lub tin yog tus, nws yog Qi ntawm halberd;
Kub thiab tin nyob hauv ib qho, Tin Bronze uas txhais tau tias qhov tawg loj yog cov sib npaug; qhov thib tsib yog kub thiab yaj yog ob, uas txhais tau hais tias xaj raug txiav thiab raug tua; cov kub thiab tin yog ib nrab, Tin Bronze uas hu ua daim iav (daim iav). Hluav Taws). ” Qhov no qhia tau hais tias ntau tshaj li 3,000 xyoo dhau los, Tin Bronze cov neeg ua haujlwm ntawm peb lub teb chaws tau paub tias kev ua tooj ua npuas nrog cov laj thawj sib txawv yuav tsum muaj cov khoom sib txawv, Tin Bronze thiab cov khoom sib tshooj ntawm cov khoom siv hlau siv los ua rau tooj dag kuj yuav tsum sib txawv.
