Amatore says that although most lead compounds, like galena, are insoluble, compounds like laurionite 'can dissolve a little bit to produce Pb2 +.'

阿玛托说，尽管诸如方铅矿一类的大部分含铅化合物都是不可容的，像羟氯铅矿这样的化合物还是“可以微溶于水，并产生Pb 2 +(二价铅离子)”。

Laurionite and phosgenite didn't occur naturally in and around Egypt, but ancient recipes showed that laurionite was synthesised by painstaking procedures, of which phosgenite was a by-product.

羟氯铅矿和角铅矿并非偶然，在埃及附近也没有类似矿藏，一份古配方显示，羟氯铅矿是通过十分复杂的步骤合成出来的，而角铅矿只是其副产物。
