在老工艺中 修壶（包）没有用银(金)的 都是用的锡 ­

银是近几年 有人为了装饰壶 把一层薄如纸的银箔(金箔) ­

用胶粘在壶上的 起到了装饰作用 对于修补来说 没有效果。银箔(金箔)的厚度不到0.1毫米，

可谓薄如纸，由于薄 金箔就没有足够的力，包在壶上，要想牢固只有两个办法

一就是直接用胶加固，二是增加金箔的厚度，起码要0.3毫米厚。

盖墙直上直下，还有尖尖的壶嘴[/B] ­

里面粗外面细。不用胶， 一定会掉下来。但是老的工艺包锡 不用胶粘 也可以做到修补 装饰的效果。 ­

用胶加固，胶有毒 遇热水有化学味，胶的正常使用温度一般都在60度左右，经常在高温下使用胶会老化 也不牢固。不能解决牢固和健康的问题。增加金箔厚度，费用直线递增，有几人能接受？

只有在没有胶的年代出现的工艺 才能解决残壶的牢固和健康 问题

下面的一些图片  壶友门看看就明白了

现在的包银工艺：
