White in the Elizabethan period edit
White lead powder was also used in the Elizabethan period as a face paint. It would also be mixed with ceruse and the lips painted. Strange this article makes no mention of this? Danny (talk) 00:53, 15 January 2010 (UTC)
- It was used at lots of times historically, and certainly warrants coverage here - especially the health aspects and the more interesting skin diseases it encouraged. Go for it Andy Dingley (talk) 10:03, 15 January 2010 (UTC)
- I have also heard that decedence in the Roman Empire resulted from the use of white lead as a cosmetic. However can reliable sources be identified for this? Peterkingiron (talk) 22:32, 15 January 2010 (UTC)
- Now that I've not heard, and it seems unlikely (from the little I know of Roman cosmetics). OTOH, rich Romans loved their defrutum, the first artificial sweetener: lead acetate, made by boiling down grape juice in lead pots. Andy Dingley (talk) 22:47, 15 January 2010 (UTC)

Use as a lubricant on lathe edit
I don't know how to do a citation and the video citation page is intractable as most of wikipedia manuals, but here is a video of a retired professor talking about it: youtu.be/08tc_fRY5ps?t=1m33s if someone with knowledge wants to fill the [citation needed] (woahou even youtube links are restricted, well I don't know, I'm trying to help but it's not gonna happen again soon) — Preceding unsigned comment added by 31.32.126.170 (talk) 21:30, 18 October 2013 (UTC)

Hydroxide edit
On the page hydroxide the formula (PbCO3)2·Pb(OH)2 is used, which somehow looks more sane to me. — Preceding unsigned comment added by SimonDeDanser (talk • contribs) 04:13, 21 July 2017 (UTC)
"Hydrate of cerussite" edit
Hydrocerussite does not contain WATER, but hydroXYL groups; it is thus not a HYDRATE, but BASIC (hydrOUS) carbonate; the more, a mineral can't be a hydrate of another mineral, e.g., CuSO4*5H2O is a pentahydrate of COPPER SULPHATE and not CHALCOCYANITE. Eudialytos (talk) 20:03, 29 August 2017 (UTC)
