I have a picture of Covellite, but I don't know how to post it on the page (not bee using wikipedia very long, sorry--I'm learning!). If someone can tell me how or give me an email so I can send it to you, that would be great.TrogdorPolitiks 20:08, 4 January 2006 (UTC)

Comment: The main article, under Applications, states that "Covellite was the first discovered natural superconductor," with Reference #11 as support. This is incorrect, unless one believes that mercury (found to be superconducting by Kammerlingh Onnes in 1911) is somehow "unnatural". Please let me know if there is a more appropriate place to submit this correction. JHBrewer (talk) 17:25, 8 October 2010 (UTC)

The abstract of the reference given states: "never observed before on natural materials" - don't have access to the full article. So it seems supported. However, as Hg was known to be superconducting since 1911 -- it would seem a clarification of exactly what was "never observed before", superconductivity in a solid mineral phase as opposed to liquid mercury? Feel free to edit and correct the article especially if you have access to the source. Vsmith (talk) 17:55, 8 October 2010 (UTC)

Rare and ubiquitous

Hi all, in the first lines it is written that the mineral is "rare", but the next sentence states it is "ubiquitous". I take it is present in small quantities when compared to the bulk but it is actually commonly found? — Preceding unsigned comment added by 137.132.228.33 (talk) 02:48, 6 March 2017 (UTC)
