Thus , such phenomena as vermilion turning black , aging of red lead and the fading of arsenic can now be more essentially represented by the chemical reactions of cinnabar having its crystal lattice transformed , lead tetroxide turned into lead dioxide , and arsenic sulfide turned into arsenic oxide 于是,朱砂变黑,铅丹老化,石黄退色等现象,便可以用硫化汞转变了晶格,四氧化三铅变成了二氧化铅,硫化砷变成了氧化砷来更本质地加以表述了。
