Lord Steve of Oxford? You get my vote!

Let me up the stakes to the highest levels of the aristocracy. Maybe Steve should become King Steve? And old use for mercury was in curing King's evil or scrofula. The King was meant to be able to touch people and cure them ... it was then found that the mercury that was being prescribed for the syphilis also cured scrofula. So, my case is that Steve will now have absorbed so much mercury, that just to touch him will cure you of scrofula. Ergo, King Steve. Sorry, it's been a stressful day arguing energy politics! Ed

I think one of the king Johns was riddled with the pox but done in by the mercury, according to history not before he went totally insane. No doubt Jonathan will give us a more accurate history lesson. Incidentally another one was murdered with a red hot poker up his backside. the arsassin's orders was to leave no mark upon his body. So being a king in those days carried it's risks. A few of 'em also got beheaded.

Further development; Had a small batch of mercury nitrate crystals in a watch glass in the shed, by the window. The sunny weather has turned it into mercury oxide. Makes me wonder if you can pyrolyse the salts with a UV lamp?

I don't think so. A quick look in Gmelin doesn't show anything. Is it really oxide or basic nitrate from hydrolysis? Ed

Slowly reacted with the oxygen in the air, basically. Here's from wiki; The red form of HgO can be made by heating Hg on oxygen at roughly 350 °C, or by pyrolysis of Hg(NO3)2. Moreover, heating the Hg(NO3)2 crystals causes them to melt, thus driving out any water, then the liquid crystal dries up and goes orange....because it's oxidized. I think the same thing has happened to the crystals I left in the sun, although the weaker colour suggests that not as much oxygen has been reacted with.

Update: Just refined the pyrolysis process this morning, now getting mercury II oxide. (was mercury I). Difference is in the particle size, but ideally HgO II is what you need for batteries. Also found a source of pure potassium hydroxide in dry flake form...ideal. ....And two sources of zinc. One is zinc oxide in powder form, the other zinc metal. The latter believe it or not is in abundance as car wheel balancing weights. Seems they went to zinc from lead. This is needed for anode material and can be melted to cast small anode ingots. I think I'll order the potassium hydroxide since I am now at that stage. Next thing it to devise a test cell, I have a novel idea of using lab glass tube with anode and cathode at the ends. In this way I can see what is going on inside. When that is proven and tested, I'll move on to making a button cell case and devise a filling method. The difficult part here is the roll-over swage forming the seal. Though I envisage turning a couple of press tools that should do the job. The seals will have to be pre cast with vulcanising silicone, should be no trouble to machine a mould for that. Ultimately I'll run into difficulty (though not insurmountable) with running out of mercury metal and having to build a small bench refinery to work the ore. Basically a small rotary furnace with continuous extraction running into a condenser. Getting there, slowly but surely.
