一件精美的古代青铜器,因多馆陈列,交换或馈赠等原因,都要依原器物复制。由于青铜的溶点高,工艺复杂,专业性强,多年来各地方博物馆搞文物修复、复制青铜器物时,都普遍使用低溶点金属来代替。如:铅锡合金、锌锡合金、铅锑合金,这几种低溶点金属都呈银白色。而古铜器物长期受到各种物质的侵蚀、氧化,器物铜胎表面颜色都是各种深浅不同的红铜色。要使低溶点金属复制品达到乱真的效果,只有在低溶点金属器物外表镀上一层铜或着颜色来解决。
A beautiful ancient bronze, due to multiple museum display, exchange or gifts and other reasons, according to the original copy. Due to the high melting point of bronze, complex technology, professional and strong, over the years to engage in local museum relics repair, replica of bronze objects, are generally used to replace the low melting point metal. Such as: pewter, zinc-tin alloy, lead-antimony alloy, these low melting point metals are silver-white. The bronze artifacts have long been a variety of material erosion, oxidation, utensils copper tire surface color is a variety of different shades of copper. To make low-melting metal replica to achieve spurious effect, only in the low-melting point metal appearance coated with a layer of copper or color to solve.
