深圳市天禅工艺品公司 / 2015-08-13

   青铜器表面的颜色,传统意义上的色斑,一般都很单调:仅限于绿锈,铁红斑,黑色调等为数不多的几种颜色。代表颜色有:国内诸多出土的青铜器文物表面的颜色,这些颜色多是在地下特定的储存坏境中,表面亲水氧化,经千年甚至更长的时间而自然形成。而青铜化学热着色是以加热为催化剂, 促使化合物与青铜表面产生化学反应,而自然生产各种颜色,以达到装饰青铜表面的效果。

  国内外铸铜雕塑行业,金属表面着色处理行业等,从上世纪80年代末期或90年代初期开始致力于青铜表面化学着色的研究。目前着色工艺已趋成熟青铜化学热着色要点:
  首先要配制正确的,好的青铜的配方;其次对铜雕表面的光洁程度有苛刻的要求,以达到着色后颜色的均匀自然;还有火候的把握,有非常的难度,不同的颜色,对温度有不同的要求,低了达不到理想色标,高了,会灼烧表面颜色;最后一个不易掌握的是化合物的浓度精确配比。

  青铜器化学热着色,不同于物理喷涂着色。着色好后的颜色,看上去就如同从铜内部透出来的一样,丰富、自然、厚重、牢固。
  青铜器化学热着色,根据产品的文化内涵和背景来制定着色方案:有的只需要一种颜色 就可达到完美效果,有些铜雕工艺品,需要几种颜色来搭配,来到达最佳艺术效果,有些写实创作的艺术雕塑,着色就复杂的多,不仅要考虑颜色的搭配,还要考虑到颜色  的过度,和斑纹的写实,如动物类铜雕工艺品
 
Color bronze surface, stains in the traditional sense, are generally monotonous: only to green rust, iron erythema, and so one of the few black tone color. Representative color: domestic color bronze artifacts unearthed many surfaces, these colors are mostly underground storage environments in particular, the surface of the hydrophilic oxide by thousands or even longer and naturally. The chemical heat colored bronze is heated catalyst, prompting compound with bronze surface chemical reaction, while natural production of various colors, in order to achieve the effect of decorative bronze surface.

Study abroad bronze sculpture industry, metal surface treatment industry and other coloring from the late 1980s or early 1990s began working bronze colored surface chemistry. Currently coloring process has matured bronze chemical heat coloring points:
First to be formulated correctly, a good recipe bronze; bronze Secondly, the degree of surface finish are demanding, in order to achieve a uniform natural color after coloring; also grasp the furnace, there is very difficult, a different color, for temperature have different requirements, low less than ideal color standard, high, and will burn surface color; the last one is not easy to grasp the exact concentration of the compound ratio.

Bronze chemical heat coloring, different from the physical spray coloring. Color after color is good, it looks like from inside shone like copper, rich, natural, thick, firm.
Bronze chemical heat coloring, according to the product's culture and background to develop a coloring scheme: some only need one color can achieve perfect results, some bronze handicrafts, several colors to match the need to achieve the best artistic effect, some Realism creative art sculptures, colored on more complex, not only to consider the mix of colors, also taking into account excessive colors and markings of realism, such as animal bronze crafts
