I really enjoy your photos, kristofvagyok, thank you for taking the time to post them. I have browsed through your tumblr album as well,
excellent work.

The photos are amazing. Could you please post the reaction? We are also interested in the chemistry, not just photos.

@Kristofvagyok how do you get you photos to display full size instead of just a thumbnail size?

Is that a tremendous old process for turning s**t into gold or something like turning lead into wine?

Thanks a lot!
The reaction is currently "secret", it still needs to be verfied by MS and I am planning to do a real time reaction check by NMR. If this works,
something new will be published soon in a journal(:
The photos are uploaded on my blog, just it's currently not published over there, here they are just linked, this is why they are in full size.

Just some quartz tubing I bought on eBay long ago and I was shining a laser level light into it. I wrote a company asking if they could identify the
kind of quartz it was, the box of 15 tubes having the Heraeus label on it. Each tube was sealed in plastic with a printout of a half dozen
specs/tolerances unique to each tube. Basically though they were all a meter by 25mm od, 19 id. They wrote me this.
"We have found some old paperwork which I can with 100% accuracy say that part#1565 was produced for Nortel and the material is Heralux WG material.
That is Flame fused natural
quartz crystals. OH content 130-180ppm, <50ppm Cl We don't produce that material any more. Now it is all synthetic F300. This natural base
material was taken from mines in Madagascar in Africa."

With how many awesome pictures you have you could make a really nice chemistry "coffee table book", with big glossy high-def pages. I would buy a copy

lol, If you could afford it, Any chemist in his right mind would spend the money on chems or glass. We have the wonderful viewing platform called
"Internet" 
Friends of mine go to Africa often and make a hardback picture book of every country. It is very nice, black pages with pictures and short
descriptions. The actual book (not including the cover) is about 1cm thick and it costs them 100EUR to get it printed.

Chlorobutanol
Here are a few photos I have taken of 1,1,1-trichloro-2-methyl-2-propanol (~2g) after 5 months of storage in the garage. The temperature was not
constant, between 10C and 20C, but it was safe in a dark cabinet away from light. It is showing signs of sublimation, not nearly as bad as others I
have seen at five months. I performed this synthesis very well, using ACS reagents, close eye on temperature, and I believe it is fairly pure. I
wasn't expecting this sublimation though.

This is the position I normally have it in, vertical.

What's the orange tint on the metal and glove? When I was about 15 I ordered a quarter pound I think from Mallinckrodt. The UPS guy left the package
with the funny warning labels with the neighbor because I wasn't home at the time.

I've noticed that on some of my sodium too. I have a smal jar of little pieces that I use for demonstrations (water ), and those pieces developed a yellow film on them. It scrapes off easily and looks
like saran wrap, strangely enough. My large jar of the rest of my pound of sodium, which I keep sealed most of the time, has no yellow whatsoever.
Everything is stored under mineral oil. I suspect since the small jar is opened more frequently, more oxygen gets in and reacts.

Sodium peroxide is yellow. Mine just has white/gray coating. That's a lot of sodium hehe

How the hall did you dry that?! Mine has been in a dessicator for 2 months and it's still wet as hell.

I had the wet silver nitrate on top of a square piece of thick glass that I put on top of a pot with boiling water in it, I angled the glass so that
there were 4 openings for steam to vent out therefore not heating the AgNO3 too much. Also, in the beginning I used a little excess HNO3 to dissolve
all the silver, then I let it sit over night, I steam dried it next morning being careful not to dry it all the way. It was basically dry two hours
after that.

The lead must have contained some copper, which is known to create those rainbow colors. Or can other metals do this as well?

I used NaOH as a dessicant and it worked fine. Also absorbs the extra acid fumes

It's called thin-film interference and occurs with oxide layers of most metals.

Looks just like Bismuth
Depending on where the lead comes from it could have any sort of alloying agents in it
