Mapambo ya Ukanda wa Shaba
Utangulizi wa Bidhaa
Copper imekuwa ikitumika kama nyenzo ya mapambo kwa historia ndefu. Kutokana na nyenzo ina ductility rahisi na upinzani mzuri wa kutu. Pia ina uso unaong'aa na ujenzi wenye nguvu. Ni rahisi kupakwa rangi na wakala wa kemikali. Imekuwa ikitumika sana kutengeneza milango, madirisha, nguo, mapambo, paa, kuta na kadhalika.
