銅壁畫又(you)叫銅(tong)浮(fu)雕(diao)（又(you)叫鏨銅(tong)或(huo)敲銅(tong)），是(shi)(shi)利用銅(tong)材料(liao)的(de)(de)(de)延(yan)展性(xing)興(xing)起來得鏨刻(ke)工(gong)(gong)(gong)藝(yi)，是(shi)(shi)我國傳統(tong)手工(gong)(gong)(gong)藝(yi)百花中(zhong)的(de)(de)(de)一枝奇葩。之中(zhong)技術據今已(yi)有幾千年(nian)的(de)(de)(de)歷史(shi)。 鍛銅(tong)工(gong)(gong)(gong)藝(yi)品的(de)(de)(de)造(zao)型，主要為平(ping)面的(de)(de)(de)片活，片活是(shi)(shi)平(ping)裝在(zai)某些器(qi)物(wu)上(shang)或(huo)懸掛起來供人欣賞。鏨刻(ke)工(gong)(gong)(gong)藝(yi)的(de)(de)(de)操(cao)作(zuo)，是(shi)(shi)在(zai)設計好(hao)器(qi)行或(huo)圖案后，按照一定(ding)的(de)(de)(de)工(gong)(gong)(gong)藝(yi)流程(cheng)，以(yi)特制的(de)(de)(de)工(gong)(gong)(gong)具和(he)特定(ding)的(de)(de)(de)技法，在(zai)金屬板上(shang)加(jia)工(gong)(gong)(gong)出千變萬(wan)化的(de)(de)(de)浮(fu)雕(diao)狀圖案。完(wan)成一件精美的(de)(de)(de)鏨刻(ke)工(gong)(gong)(gong)藝(yi)品需要十多道(dao)工(gong)(gong)(gong)藝(yi)流程(cheng)，加(jia)上(shang)技術工(gong)(gong)(gong)人的(de)(de)(de)格調(diao)創造(zao)，匠心獨運地(di)打(da)造(zao)出個(ge)性(xing)化，現代化的(de)(de)(de)雕(diao)塑作(zuo)品。 　

      鍛銅(tong)(tong)是一種(zhong)區(qu)別于鑄銅(tong)(tong)的(de)工(gong)(gong)藝，是在銅(tong)(tong)板上(shang)進行創作，利(li)用銅(tong)(tong)板加(jia)熱(re)后質地變軟(ruan)，錘打后又(you)恢(hui)復堅硬的(de)特性，重復這一過程(cheng)，最(zui)終制作出藝術作品或其它生活、工(gong)(gong)業(ye)用品。隨著人民生活水平和(he)審美情趣(qu)的(de)提升，鍛銅(tong)(tong)這一傳(chuan)統工(gong)(gong)藝尤其在工(gong)(gong)藝美術領域受到越來越多設(she)計(ji)師和(he)大眾(zhong)的(de)喜愛。 　

      火、錘(chui)子和鏨子是(shi)鍛(duan)銅(tong)的三個重要(yao)元素(su)。小型鍛(duan)銅(tong)工藝作品或大型浮雕局部加工可以(yi)采(cai)取(qu)氧氣(qi)加乙炔(gui)產生的高(gao)溫(wen)加熱，大型作品就需要(yao)生爐火鼓風加熱。加熱這(zhe)一環(huan)節(jie)相對(dui)容易。加熱后的銅(tong)板(ban)要(yao)用皮(pi)錘(chui)敲打平(ping)整。
