解釋
四氧化三鉛-
Occasionally red lead is added to the leady oxide.
有時將鉛丹加到鉛粉中。 -
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
於是,硃砂變黑,鉛丹老化,石黃退色等現象,便可以用硫化汞轉變了晶格,四氧化三鉛變成了二氧化鉛,硫化砷變成了氧化砷來更本質地加以表述了。
