Code Breaker 45 different names for mercury

[caesarpk]

In Code Breaker 45 page 6 (http://mangahelpers.com/downloads/read-online/32091/6), the character calls mercury by three names: 汞（こう）,汞（みずがね）,水銀

I went with Hydrogyrum, Liquid Silver, and Mercury

I would appreciate any suggestions as to how to distinguish them in English

Do you mean hydrargyrum? Well, either way, I think that's pretty much the best option out there. 汞=Archaic kanji for mercury, and hydro/hydrargyrum=Latin for mercury, so it fits nicely.

The website I looked up (by googling) said it was hydrogyrum so I went with that, but I'll make sure if it's hydrargyrum or hydrogyrum.
Thanks! Somebody saisd quicksilver but I'm not sure about that option.

EDIT: Wikipedia said mercury is called quicksilver or hydrargyrum. So I'm going with these two. Thanks again.
