銅壁畫又叫(jiao)銅(tong)(tong)浮雕(diao)（又叫(jiao)鏨銅(tong)(tong)或敲銅(tong)(tong)），是利(li)用銅(tong)(tong)材料的(de)(de)延展性(xing)興起來(lai)(lai)得鏨刻工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)，是我國(guo)傳統手工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)百花中的(de)(de)一(yi)枝奇葩(pa)。之中技術據(ju)今已(yi)有幾千(qian)年(nian)的(de)(de)歷史。 鍛銅(tong)(tong)工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)品的(de)(de)造型，主要為(wei)平面的(de)(de)片活，片活是平裝在(zai)(zai)(zai)某些器(qi)物上(shang)或懸掛起來(lai)(lai)供人(ren)欣賞(shang)。鏨刻工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)的(de)(de)操(cao)作，是在(zai)(zai)(zai)設計好器(qi)行或圖案(an)后，按(an)照一(yi)定的(de)(de)工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)流(liu)(liu)程(cheng)，以特制的(de)(de)工(gong)(gong)(gong)(gong)(gong)具和特定的(de)(de)技法，在(zai)(zai)(zai)金屬板(ban)上(shang)加(jia)工(gong)(gong)(gong)(gong)(gong)出千(qian)變萬化的(de)(de)浮雕(diao)狀(zhuang)圖案(an)。完成一(yi)件(jian)精美的(de)(de)鏨刻工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)品需要十(shi)多(duo)道工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)流(liu)(liu)程(cheng)，加(jia)上(shang)技術工(gong)(gong)(gong)(gong)(gong)人(ren)的(de)(de)格調創造，匠心獨(du)運(yun)地打造出個性(xing)化，現代化的(de)(de)雕(diao)塑作品。 　

      鍛銅(tong)是一(yi)種區別于(yu)鑄(zhu)銅(tong)的(de)工藝(yi)，是在(zai)銅(tong)板上進行創作，利用銅(tong)板加(jia)熱后質地變軟，錘打后又(you)恢復堅硬的(de)特性，重復這一(yi)過程，最(zui)終制作出藝(yi)術作品(pin)或(huo)其它生活、工業用品(pin)。隨著人民生活水平和審美(mei)情趣的(de)提升，鍛銅(tong)這一(yi)傳(chuan)統工藝(yi)尤(you)其在(zai)工藝(yi)美(mei)術領域受到越(yue)來越(yue)多設計師和大(da)眾的(de)喜愛。 　

      火、錘子(zi)和鏨子(zi)是鍛銅(tong)的(de)三個重(zhong)要元(yuan)素。小型(xing)(xing)鍛銅(tong)工藝(yi)作品(pin)或(huo)大型(xing)(xing)浮雕局(ju)部加(jia)工可以采取氧氣加(jia)乙炔產生的(de)高溫(wen)加(jia)熱(re)，大型(xing)(xing)作品(pin)就需要生爐火鼓(gu)風加(jia)熱(re)。加(jia)熱(re)這(zhe)一(yi)環節相對容易。加(jia)熱(re)后的(de)銅(tong)板要用皮錘敲打平(ping)整(zheng)。
