Wasn't this also used as a medicine once? Near the end of the main article about George Washington, there's a claim that he lost most of his teeth from using it. —Preceding unsigned comment added by 24.143.230.46 (talk) 01:53, 30 September 2007 (UTC)[reply]


More Uses

Could someone post some more uses for this compound?? 82.43.183.13 (talk) —Preceding comment was added at 13:09, 19 January 2008 (UTC)[reply]


On the 'red' page, it's listed as a red pigment. I don't have time to look it up right now, and I don't know anything about its use as a pigment, but there should be something here, since it's linked from that menu. I won't have time to edit this for months (exams...) and I'll probable forget about it, so if anyone else knows about this, it might be a good idea to add it.

Removed

The following in the 'History' section, as it is concerned with oxygen and not mercuric oxide:


Lavoisier identified this "dephlogisticated air" as "oxygen" due to the acidic compounds that the gas produced.[1] This is why the textbook account of the discovery of oxygen is inaccurate in the sense that it is really impossible to answer who "discovered" oxygen. This was, however, one of the major milestones of chemistry. Before Priestley, oxygen had been discovered by the Swedish chemist Carl Wilhelm Scheele some time before 1773, by the same method as Priestley. However, Priestley's discovery was published already in 1775 and Scheele's not until 1777,[2] which is claimed to be because of a very long delay on the part of the publisher. --92.30.237.119 (talk) 00:52, 28 March 2010 (UTC)[reply]

(repost as I missed the deletion edit). Fine. The part above was probably copy/pasted from another article without correcting for relevance to HgO. Materialscientist (talk) 01:07, 28 March 2010 (UTC)[reply]

Mercury oxide and 'cinnabar'

I was wondering if someone could clarify the following section of this article: "mercury oxide has two crystalline forms: one is called montroydite [...] and the second, cinnabar [...]". I only know cinnabar as a name for MgS (and in the article it is wikilinked to that compound), but it appears to be being used here as a name for a crystal structure. My (brief) attempt to confirm that this is correct hasn't gotten me anywhere. Could someone confirm that this is correct and possibly add some explanatory text into the article and perhaps remove the misleading link to MgS?
Many thanks and all the best. –Syncategoremata (talk) 14:38, 19 May 2010 (UTC)[reply]

You are correct--cinnabar is a sulfide, not an oxide. However, note that montroydite incorrectly redirects to this page, whereas it should have its own page. -71.203.125.108 (talk) 08:53, 17 November 2010 (UTC)[reply]
