八月底的时候看到新买的硫酸亚铁，决定用它培养晶体，因为手头没有还原铁粉，就采用加入抗坏血酸，硫酸，表面覆盖一层石蜡油的方法防止氧化和水解，可能是因为溶液配置是没有完全饱和，导致培养时间特别长，放在角落...

我这里算是南方，一年里总有几个月非常潮湿。衣柜里常用除湿袋来保持干燥。我用的是那种氯化钙的除湿袋。原理很简单，就是一个袋子，分了两格，上面一格的材料是透气的，里面装了无水氯化钙。下面一格是塑料，一开始...

我在培养前借鉴了前人的制作办法来制作硫酸铜晶体，但是每一次都出现一个神奇的现象在溶液表面出现很小的结晶（为什么说是结晶呢，因为我把这些拿出来之后加水是溶解了的）然后就是配置溶液时出现的问题（没拍到图）...
