Kumnyaka we-1200 BC abanye abantu baafunda ukwenza izixhobo ze-iron nezixhobo zemfazwe. Ezi ke zazomelele kunjalo nje zinamandla kune-bronze kwaye ke oku kwaba lithuba elifanelekileyo dvantage ikwimfazwe. Kungoku nje ixesha lezixhobo ze-iron nezixhobo zemfazwe libizwa ngokuba yi-Iron Age. Ii-metals bezisoloko zibaluleke kakhulu kwimbali yoluntu nakwi-mpucuko. I-iron ne-steel zazibalulekile ekwenzeni oomatshini. IGold ne-silivere wzazisetyenziswa njengemali ukuze kuvunyelwe abantu uba bashishine, oko kuthetha ukuthi, kutshintshiselwane ngempahla anangee-nkonzo zemisebenzi kwimigama .emide.

Umzekelo, masithi ubude bakho babuziisentimitha ezingama-60 xa kanye wawunonyaka omnye ubudala, baza bonyuka baziisentimitha ezingama-85 xa wawuneminyaka emi-2 uzelwe, baphinda bonyuka ubude bakho baziisentimitha ezingama-95 xa uminyaka mi-3 uzelwe. Apha engqondweni yakho ungazikrwelela umgca ongqalileyo onqumla kuphawu lwesentimitha ezingama-50 ubude kumgca obheka phezulu. uphinde uzobe owesibini umgca onqumla uphawu olubonakalisa umnyaka om-1 ubudala kumgca oxwesileyo oya ngasekunene. Apho idibana khona le migca mibini ikumfanekiso-ngqondweni wakho (masithi kusemdibanisweni wayo), ungabeka ichaphaza njengophawu lwakho. Inene, le migca ikumfanekiso-ngqondweni wakho, idla ngokwenziwa kwiphepha legraf (khawujonge apha ngezantsi). Ukuzotywa kwalo mdibaniso kuthiwa ""luphawu lwamanqaku eesentimitha ezingama-50 ngonyaka om-1''.

Kwiminyaka engaphaya kwama-9000 abantu baqala ngokwenza izinto nge-metal, xa babefumananisa okokuba bangayifumana njani na i-copper kwi-ore yayo. Baza ke ngoko bafunda okokuba yenziwa njani na ialloy eyomeleleyo, ibronze, ngokugalela i-tin kwi-copper. Malunga neminyaka engama-3000 eyadlulayo, babhaqa i-iron. Bathi besagalela intwana ye-carbon kwi-iron, bafumanisa okokuba bangenza i-alloy ebalulekileyo - esi-steel.

Satyagraha eyaziwa nje nge ndlu ka Gandhi iyiMuseum ne ndlu yaba vakashi ifumaneka eJohannesburg. lendlu yeyeka Mahatma Gandhi waye hlala futhi esebenza khona ngonyaka ka 1908 kuze kbe ngu 1909.
