銅壁畫又叫銅(tong)浮雕(diao)（又叫鏨(zan)銅(tong)或(huo)敲銅(tong)），是(shi)利用(yong)銅(tong)材(cai)料的(de)(de)延展性(xing)興起來得鏨(zan)刻(ke)工(gong)(gong)(gong)(gong)藝(yi)，是(shi)我國傳(chuan)統手工(gong)(gong)(gong)(gong)藝(yi)百花中的(de)(de)一枝(zhi)奇(qi)葩。之(zhi)中技術據(ju)今(jin)已有幾(ji)千(qian)年的(de)(de)歷史(shi)。 鍛(duan)銅(tong)工(gong)(gong)(gong)(gong)藝(yi)品(pin)的(de)(de)造型，主要(yao)為平面的(de)(de)片活，片活是(shi)平裝在某些器物上(shang)或(huo)懸掛起來供人欣賞。鏨(zan)刻(ke)工(gong)(gong)(gong)(gong)藝(yi)的(de)(de)操作(zuo)，是(shi)在設計好(hao)器行(xing)或(huo)圖(tu)案后，按照一定(ding)的(de)(de)工(gong)(gong)(gong)(gong)藝(yi)流程(cheng)，以(yi)特制(zhi)的(de)(de)工(gong)(gong)(gong)(gong)具和特定(ding)的(de)(de)技法，在金(jin)屬板上(shang)加工(gong)(gong)(gong)(gong)出(chu)千(qian)變(bian)萬化的(de)(de)浮雕(diao)狀圖(tu)案。完成一件精(jing)美的(de)(de)鏨(zan)刻(ke)工(gong)(gong)(gong)(gong)藝(yi)品(pin)需要(yao)十多(duo)道工(gong)(gong)(gong)(gong)藝(yi)流程(cheng)，加上(shang)技術工(gong)(gong)(gong)(gong)人的(de)(de)格調創造，匠(jiang)心(xin)獨運地打造出(chu)個性(xing)化，現代化的(de)(de)雕(diao)塑作(zuo)品(pin)。 　

      鍛(duan)銅是一(yi)種區別(bie)于鑄銅的工(gong)藝，是在銅板(ban)上進行創作，利(li)用銅板(ban)加熱(re)后(hou)質地變軟，錘(chui)打后(hou)又恢復(fu)堅硬的特性，重復(fu)這(zhe)一(yi)過(guo)程，最終制作出(chu)藝術作品或其它生活、工(gong)業用品。隨著(zhu)人民(min)生活水平和審美(mei)情趣的提升，鍛(duan)銅這(zhe)一(yi)傳統工(gong)藝尤其在工(gong)藝美(mei)術領(ling)域受到越(yue)來(lai)越(yue)多設計(ji)師和大眾的喜愛。 　

      火、錘(chui)子和(he)鏨(zan)子是(shi)鍛(duan)銅(tong)的(de)三(san)個重要(yao)元素。小型(xing)(xing)鍛(duan)銅(tong)工藝作品(pin)(pin)或大(da)型(xing)(xing)浮雕局部加(jia)(jia)(jia)工可以采(cai)取氧氣加(jia)(jia)(jia)乙(yi)炔產生的(de)高(gao)溫加(jia)(jia)(jia)熱，大(da)型(xing)(xing)作品(pin)(pin)就(jiu)需(xu)要(yao)生爐(lu)火鼓風加(jia)(jia)(jia)熱。加(jia)(jia)(jia)熱這一環節相(xiang)對容易(yi)。加(jia)(jia)(jia)熱后的(de)銅(tong)板要(yao)用皮錘(chui)敲打平整。
