铜大缸采用树脂砂铸造，工艺好，不走形，采用62#焊条，气焊焊接跟整体铸造效果一样，还有这种焊条不与纯铜产生氧化，不会反绿锈。这就是62#焊条的价值所在。铜大缸再焊接、打磨，完成后，进行表面处理，做颜色，着色化学药腐蚀。用火枪烤到一定的温度用喷壶喷在上面，让药水吃到铜里面这样用不掉色，色泽永远都是就像刚做的一样。保留的时间上，{可以达到100年都没问题}因为药水能吃到铜里面0.5mm。

The copper cylinder is made of resin sand, with good technology and shape free. 62 × electrode is used. The gas welding has the same effect as the overall casting, and the electrode does not oxidize with pure copper and will not reverse green rust. This is the value of 62 X electrodes. The copper cylinder shall be welded and polished again. After completion, the surface shall be treated, colored and chemically corroded. Bake it to a certain temperature with a torch and spray it on it with a spout. Let the liquid medicine eat into the copper so that it will not fade. The color will always be the same as just made. In terms of retention time, {it can reach 100 years without any problem} because the liquid medicine can eat 0.5mm into copper.
