So I tried precipitating sodium potassium cyanide with a mixture of ethanol and butanol. It seemed to do a little bit better (emphasis on the SEEMED TO part). I have not had a chance to quantify it yet. The cyanide problem is now the only real obstacle to octacyanomolybdate. The new prep should be exceptionally easy to carry out. Hopefully dissolving the cyanide in methanol to recover it will yield better results than water does.

A 1 gram bar of platinum that has dissolved enough for the crystals in the metal to become visible.

Someone made an incredible donation to the channel yesterday. I don't want to call people out and post a name because they have not specifically told me it was OK to do so. But with their donation I was able to get the following:

1 pound of ammonium perchlorate which I will use to make other perchlorates and perchloric acid (either as the pure acid or in-situ from a highly soluble perchlorate). 

1 pound of realgar powder which I will use to do some arsenic chem and pyro mixes (it came from a fireworks supply company). I should even be able to make some of the ever elusive arsenic trioxide with it. If Basil Valentine could pull it off how hard can it be? 

1 pound of pyro grade antimony trisulfide for pyro mixes and other antimony chem. That element is far from played out.

2 pounds of barium chlorate for making other chlorates and probably some pyromixes as well

1 new stir/hot plate that can get hot enough to boil water easily and that won't die in 3 months

5 pounds of sodium hydroxide

5 grams of thallium. I know you all don't like the thallium chems as much (or YT is suppressing the hell out of them) but there is a core audience for those videos who share my fascination with this wrongly maligned element. 

1 gram of thulium

1 blue watch lume kit. I believe the lume contains lumanova or super luminova (strontium aluminate). I have been doing research on restoring the glow to radium dials and this compound was said to give great results. I have a collection of radium dials (I think about 15 at this point) plus some radium sulfate in a barium sulfate matrix. I would like to extract the radium and combine the lume with it to create a modern amateur take on the classic Undark paint. Failing that I can always apply the lume to the watch dials and restore their glow. Either way we are going to get to see radium make shit glow in the dark. I went with blue lume so it would look all cool and cherenkov-y. :-) 

All of that came to slightly more than the donation but that's alright. I was happy to chip in. :-)

Working on the next video which will be the prep of rubidium terbium sulfate. I was going to make plain terbium sulfate because it fluoresces a beautiful green color (europium sulfate fluoresces reddish and thulium sulfate fluoresces blue; might do them in a future video). However, someone already did a video on terbium sulfate nine years ago and I hate to repeat stuff others have already done. As it turns out you can precipitate terbium sulfate from aqueous solution by adding potassium sulfate solution to it. However I did not have any potassium sulfate but I did have rubidium and cesium sulfates (I use them to make Rb and Cs salts by metathesis with Ba salts). Given that rubidium is closer to potassium I decided to go with that. It's evaporating down now and I am getting some nice crystals. Hopefully it is still fluorescent!! The terbium, europium, and thulium halides are not so the anion does make a big difference. Hopefully an extra cation won't make it unhappy.

The picric acid solution always precipitates crystals of picric acid when it gets cold outside. I have never seen it actually freeze. No matter how cold it gets out here the solution remains completely liquid. The coldest winter nighttime temperature in upstate South Carolina in is about -10C/14F although most of the time it is not THAT cold. There are many days in winter where I can comfortably sit outside in jeans and a t-shirt during the afternoon. Water that is left out overnight does not freeze at all most of the time. That's not to say the winters here are balmy; it usually gets down into the 30s or 40s at night (F). We almost never get any snow but we do get cold, dreary rain come through every few days. That's always fun. It's too cold to run a dehumidifier in the shed so I have to wrap up EVERYTHING I don't want corroding in well sealed plastic.
