[@bsul03420]

Over 60 years ago, when I was a schoolboy, I remember my chemistry teacher telling me about an international incident resulting from this allotrope of tin. After all this time I'm not sure I can remember all the details, but it seems that a large quantity of tin was required by a foreign power ( I think it was Russia) and they negotiated a deal with the British government to buy Cornish tin from the UK. A large ingot was crated up and, upon payment of the negotiated sum, the shipment was duly sent. In the nineteenth century, the sea voyage took several weeks sailing through arctic waters and, when it finally arrived, the crate was opened only to find a horrible powdery mess within. Naturally, the customer believed the British government had swindled them and it took quite a time before it was realised that prolonged exposure to sub-zero temperatures had brought about the change of state and that the contents of the crate could be melted down and the ingot re-cast!

That was my thought when I got to the end of the video with no mention of tin whiskers/tin pest! Got a real chuckle when I saw you had already made this comment. The other thing I found missing was the fact that tin has more stable isotopes than any other element. Now I suppose this isn't specifically related to chemistry, but I am curious of this has ever been put to any practical use.

"Commercial grades of tin (99.8%) resist transformation because of the inhibiting effect of the small amounts of bismuth, antimony, lead, and silver present as impurities." - wikipedia page on tin

[@JoshuaScalf]

Matthijs van Duin thanks for sharing

[@MatthijsvanDuin]

In case it's not clear why I quoted this: it is a potential explanation of why they failed to transform beta-tin into alpha-tin in this video.

[@faxezu]

The unstable α-tin forms below 13°C but only if other conditions are right. As mentioned the composition has to match and ideally a seed crystal with matching crystal structure exists in the sample to start the transformation.

[@TheDuckofDoom.]

Whole industrial rail shipments have turned to powder when transported through Russia in winter. I doubt that these were of a lab grade purity. But then virgin material is usually less contaminated with other metals than recycled material so maybe it is just a matter of the specific impurities.

[@matteofabbris7877]

probably dry ice would have given better results. Anyway, I guess this creates problems in using Tin to solder aerospace devices... it would be nice to learn more

[@mixtermuxter8602]

The Tin Pest could have used a little bit more explaination. Also Cody, from "Cody's Lab" got the transformation to grey tin going much faster. He did it on dry ice with a starter seed of grey tin. Your video is still very nice.

Something you might not know: aluminium and tin will also oxidize, the key difference being that they form a stable oxide layer at their surface that shields the underlying material. When iron oxidizes (rusts), it breaks up in flakes, exposing the underlying material, which then also rusts, etc.

Aw, you talked about pewter plates, but you should have mentioned why people used to think tomatoes were poisonous! With the tin/lead-based pewter, when people ate acidic foods like tomatoes, of course it would bring lead into the solution, here as lead citrate. Of course, over time, people fell ill due to it, and people logically blamed the tomatoes instead of the plates!

[@TheCarbonMirror]

Really more of a lead fact isn't it? It may be mentioned in the lead video, it would be a bit out of place in a Tin video

[@erikawanner7355]

Actually tomatoes are a member of the nightshade family which is poisonous so that’s partly why they thought tomatoes were also poisonous.... the leaves are the poisonous part of the plant

I love tin. Tin has almost the same mass as iron. Tin is very easy to melt and it casts very well. It is fairly hard and strong when it solidifies. It takes a very nice polish and does not tarnish easily. Tin used to be one of the main metals used in making telescope mirrors. This copper-tin alloy is called speculum metal. My understanding of tin pest is that it requires a seed before it begins transforming into the alpha allotrope. That’s why it starts at a point and grows from there rather than transforming from all over and inside more or less at the same time. So in these videos, tin even at low temperature can remain stable in the beta form for a long time. But once the transformation starts it can happen quickly. So maybe you need to poke your tin samples with a tiny bit of the alpha allotrope to get things started.

[@JackedUpTricks]

Just an appreciation post to this channel. You've made such amazing videos for last few years, and still going strong. I love how captivating your videos have been and how informative they have been.

SnCl4 catalizes formation of acetone peroxide (tetrameric form to be exact). Yet another not widely known application of tin :D

[@MandrakeFernflower]

Krzysztof Matuszek most industries use tertiary butyl hydroperoxide as a radical initiator instead of AP tetramer because of explosion concerns

[@Pow3llMorgan]

A note: Soldering has been used for much longer than electronics have existed. Lead and copper roof cladding has been soldered for centuries as have the earliest forms of _tin_ cans :) Another very interesting use of tin is in the process of making pane glass. They use a liquid bath of tin and pour a layer of molten glass from a continuous furnace onto it. Because the melting point of glass is almost 1200 degrees higher than that of tin, the glass solidifies very quickly and because the tin is dense and liquid, its surface is very smooth. Brilliant engineering = nice glass windows!

[@jsvgh3504]

About a hundred years ago, my great grandfather's occupation was related directly to Tin. In those days people used the cookware made of Copper and since Copper reacts with acidic food and releases poisonous compounds, then they had to cover their cookware with a layer of Tin and that is what my great grandfather used to do. That's why my family name is "Qal' Kar", which means "the person who works with Tin" in Persian.

[@MuraliKrishna-rq1ie]

In Hindi this is called Kalai-wala

[@gordonlawrence4749]

Only one quibble as an electronic engineer. That PCB looked like it was late 1980's vintage or possibly earlier. At that time solder was usually 60/40 tin/lead. It was not till the late 90's that Pb free became widespread and even then some industries have exemptions like military and aerospace due to tin whiskers shorting circuits over time and the traditional tin/lead mix being much more stable over the military/aerospace temp range (-55 to +125C).

[@longcat45]

I have a strong distaste for lead free solder. It doesn't wick as well and doesn't hold onto heat as well.

[@gordonlawrence4749]

Those are the least of the problems. It never flows as well as tin/lead and that whiskering problem is killing electronica all over the world.

[@TheDuckofDoom.]

Automotive and medical are also excepted, basically any and all devices that need to be reliable(both in long term use and in initial defects) still favor leaded solder. If they can find compatible components that is, sourcing is becoming a serious issue in this regard.

Is tin pest related to tin whiskering- the bane the electronics industry?

[@Glumi100]

I am not a 100% in the theory of tin whiskering, but if i got it right, then the problem is that there are small filaments growing out of the tin surface, which can result in a short circuit. Since the tin pest would effekt the whole mass of tin and is a complete destruction of the metal structur of the surface (alpha tin: has a diamond-cubic, beta tin: has a tetragonal [metal] structur). Phase changes of compounds happen mostly thorough the whole mass of the compound. The alpha tin is also a semiconductor and not a conductor like the beta tin. So i guess in electronics the bigger problems are high temperatures, that go near the melting point of tin and through rearrangement of the tin atoms there are those filmaments growing. Propably the direction of the filmaments is guided by electric/magnetic fields above the surface. Please correct me if i got something wrong.

[@lNOFXlCronier]

B. Hagedash the old solder in electrics/electronics was a an alloy of tin and lead. It is that lead stopped tin whiskers but we just don't know how, probably simply because no studies have been done on this. Now days solder is usually still primarily tin but is specifically formulated to avoid tin whiskers. Tin in electronics is the main cause of the whiskers but other metals can grow whiskers as well.

[@arbazna]

Lead-tin alloys don't have that issue. Is the unleaded solder that is the bane of electronics soldering

[@lNOFXlCronier]

arbazna yes, the lead-tin alloy does not seem to make whiskers. But alone both lead and tin have been seen growing whiskers.

[@TheDuckofDoom.]

Whiskers can form in storage, no need for temperatures near the melting point. Temps that high are not seen anyway because tin has a rather high melting point and such temps would cause rapid component degradation in service.

[@jasongnome]

I have managed to make the other form of elemental tin. But it took a LOT of patience. Many years ago I was talking about the allotropes with a year 10 (14-15yo) class, and we put a beaker containing a few pieces of elemental tin in the freezer (normal freezer, about -18C). It still hadn't chaged by the time they graduated aged 18. I forgot all about it until a couple of years later when I was looking for something else in the freezer and found it, there was a small amount of greyish dust. I've been working in the same school for 14 years now, and left it in there the whole time, I now have a beaker of grey tin.
