銅壁畫又(you)叫銅浮雕(diao)(diao)（又(you)叫鏨銅或(huo)敲銅），是利用(yong)銅材(cai)料的(de)(de)(de)延(yan)展性興起來得鏨刻(ke)(ke)工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)，是我國傳統手工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)百花中的(de)(de)(de)一枝奇葩。之中技(ji)術據(ju)今已有幾千年的(de)(de)(de)歷史(shi)。 鍛銅工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)品(pin)的(de)(de)(de)造(zao)型，主要(yao)(yao)為平(ping)(ping)面的(de)(de)(de)片活，片活是平(ping)(ping)裝在某(mou)些器(qi)(qi)物上(shang)或(huo)懸掛起來供人欣賞(shang)。鏨刻(ke)(ke)工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)的(de)(de)(de)操作(zuo)，是在設計好器(qi)(qi)行或(huo)圖案后，按照一定(ding)的(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)流程，以特制的(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)具和特定(ding)的(de)(de)(de)技(ji)法(fa)，在金(jin)屬板上(shang)加(jia)工(gong)(gong)(gong)(gong)(gong)出千變萬化的(de)(de)(de)浮雕(diao)(diao)狀圖案。完成一件精美(mei)的(de)(de)(de)鏨刻(ke)(ke)工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)品(pin)需要(yao)(yao)十(shi)多道工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)流程，加(jia)上(shang)技(ji)術工(gong)(gong)(gong)(gong)(gong)人的(de)(de)(de)格調創造(zao)，匠(jiang)心獨(du)運(yun)地打造(zao)出個性化，現(xian)代化的(de)(de)(de)雕(diao)(diao)塑作(zuo)品(pin)。 　

      鍛銅(tong)(tong)是一種區別于鑄銅(tong)(tong)的工(gong)藝，是在銅(tong)(tong)板上進行創作，利用銅(tong)(tong)板加熱后質地變軟，錘打后又恢復堅硬的特性，重復這一過程，最終制作出藝術作品(pin)或其它生(sheng)活、工(gong)業(ye)用品(pin)。隨著人民生(sheng)活水平和審美情趣的提(ti)升，鍛銅(tong)(tong)這一傳統工(gong)藝尤其在工(gong)藝美術領域受到越來(lai)越多(duo)設計師和大(da)眾(zhong)的喜愛。 　

      火、錘子(zi)和鏨子(zi)是鍛(duan)銅(tong)的(de)三個重要元素。小型鍛(duan)銅(tong)工(gong)(gong)藝作品或大型浮雕局部(bu)加(jia)工(gong)(gong)可以(yi)采取氧氣加(jia)乙炔產生(sheng)的(de)高溫加(jia)熱(re)，大型作品就需要生(sheng)爐火鼓(gu)風加(jia)熱(re)。加(jia)熱(re)這一環節相對(dui)容(rong)易。加(jia)熱(re)后的(de)銅(tong)板要用(yong)皮(pi)錘敲打平整(zheng)。
