銅壁畫又叫銅(tong)浮(fu)雕(diao)（又叫鏨(zan)(zan)銅(tong)或(huo)敲銅(tong)），是利用銅(tong)材(cai)料的(de)(de)(de)延(yan)展(zhan)性興起來得鏨(zan)(zan)刻工(gong)(gong)(gong)(gong)(gong)藝(yi)，是我國(guo)傳統(tong)手(shou)工(gong)(gong)(gong)(gong)(gong)藝(yi)百(bai)花中的(de)(de)(de)一枝奇(qi)葩。之中技術(shu)據(ju)今已有幾千(qian)年的(de)(de)(de)歷史。 鍛銅(tong)工(gong)(gong)(gong)(gong)(gong)藝(yi)品(pin)的(de)(de)(de)造型，主要為平面的(de)(de)(de)片(pian)活，片(pian)活是平裝在(zai)某些器物上或(huo)懸掛起來供(gong)人欣(xin)賞。鏨(zan)(zan)刻工(gong)(gong)(gong)(gong)(gong)藝(yi)的(de)(de)(de)操作，是在(zai)設計(ji)好器行(xing)或(huo)圖(tu)案后，按(an)照一定(ding)的(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)藝(yi)流程(cheng)，以(yi)特制的(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)具和特定(ding)的(de)(de)(de)技法(fa)，在(zai)金屬(shu)板上加(jia)工(gong)(gong)(gong)(gong)(gong)出千(qian)變萬化的(de)(de)(de)浮(fu)雕(diao)狀(zhuang)圖(tu)案。完成一件精美的(de)(de)(de)鏨(zan)(zan)刻工(gong)(gong)(gong)(gong)(gong)藝(yi)品(pin)需(xu)要十多道工(gong)(gong)(gong)(gong)(gong)藝(yi)流程(cheng)，加(jia)上技術(shu)工(gong)(gong)(gong)(gong)(gong)人的(de)(de)(de)格調創造，匠心獨運地打造出個性化，現(xian)代化的(de)(de)(de)雕(diao)塑作品(pin)。 　

      鍛銅是(shi)一(yi)(yi)種區別于鑄銅的(de)工(gong)藝，是(shi)在銅板上進(jin)行創作(zuo)，利用銅板加熱(re)后質地變軟，錘打(da)后又(you)恢(hui)復(fu)(fu)堅硬的(de)特(te)性，重復(fu)(fu)這一(yi)(yi)過程，最終制作(zuo)出藝術作(zuo)品或其它(ta)生活、工(gong)業用品。隨(sui)著人(ren)民生活水平和審美情趣的(de)提升(sheng)，鍛銅這一(yi)(yi)傳統工(gong)藝尤其在工(gong)藝美術領域受到越(yue)來越(yue)多設計(ji)師和大(da)眾(zhong)的(de)喜(xi)愛(ai)。 　

      火(huo)、錘(chui)子和鏨子是(shi)鍛銅(tong)的三個重要元素。小型鍛銅(tong)工(gong)藝(yi)作(zuo)品(pin)或大型浮(fu)雕局部加(jia)工(gong)可以采取氧氣加(jia)乙(yi)炔產生(sheng)的高溫加(jia)熱，大型作(zuo)品(pin)就需要生(sheng)爐火(huo)鼓風加(jia)熱。加(jia)熱這一(yi)環節相對容(rong)易。加(jia)熱后(hou)的銅(tong)板要用皮(pi)錘(chui)敲打平整。
