鎏金不同于贴金，鎏金工艺是我国一种传统的金属工艺装饰技法。加热水银，将黄金溶于水银之中，形成金泥，涂于铜或银表面加温，使水银蒸发，金就付在器表面上，称之”鎏金”。汉代时称“金涂”或“黄涂”，唐代称“镀金”，近代称“火镀金”，这种技术在春秋战国时就出现了，至今有两千多年的历史。
Gilding is different from gilding. Gilding is a traditional decorative technique of metal technology in China. Heat the mercury, dissolve the gold in the mercury, form the gold mud, apply it on the copper or silver surface, heat it, make the mercury evaporate, and the gold is paid on the surface of the instrument, which is called "gilding". In Han Dynasty, it was called "gold coating" or "yellow coating", in Tang Dynasty, it was called "gold plating", in modern times, it was called "fire gold plating". This technology appeared in spring and Autumn period and Warring States period, and has a history of more than 2000 years.
