well crystals can conduct electricity because of how they are made.... kinda like an led diode.... why not try that with this metal? we already know it has all kinds of different properties.... why not try and see?
@jeffddow not sure but about 50 - 100 g if not more, its a quite dense element. You can always use a thin can like redbull ones. Depends on what do you need it for.
Hey Fonserbc is bismuth easy to remove from the pan or the things you've used to cooled the molten bismuth metal? I want to attempt this experiment but want to know more about the procedure also. Thanks
@Aranwu I would say yes, when it gets cold it's easy to remove it, but maybe the sides and the bottom of the pan get impregned by particles of bismuth.
I used an old pan that I use to melt metals for in case.
@daenumen Ah!, no, no magnets, those rings were from iron/steel, but it wasn't a good idea, because they expanded because of the hot, so when they become cold, they contract and made as much preassure on the bismuth that i couldn't take it out.
@Fonserbc well you could test if bismuth expands when cooled then. i do not believe iron will expand greatly at 200celcius, but you could measure this also with a rod.
some people are under the impression that solid bismuth floats, yet it seems to solidify from its molten state from the bottom, ice usually sits ontop of water when freezing?
@daenumen Well, I looked it up on the wiki and its true that molten bismuth has a mayor density (10.05 g·cm−3) than solid bismuth (9.78 g·cm−3) so as you said it should behave as ice and liquid water. However in all the moltens of bismuth i made in this video, maybe because of the way of cooling, the bismuth started solidifying from the botom and the exterior. but when it is starting melting at the begining of the vodeo, you cans see how it floats 1:13
@Fonserbc mmm very interesting. though i wonder if the floating metal is like the 'skin on milk', where it is more solidified, or surface tension?
short of cooling it down in an insulated vessel, (to see if it then solidifies from the top - where there is then a larger temperature gradient for cooling, metal conducts heat away, and has heat capacity also - more contact surface for heat transmission than 'air').
Oh, i'm sorry. I used some kind of powder bismuth, and when i triet to melt it, it didn't melt. It just became red. And i'm sure the temparature was high enough. And if you still don't understand what i mean, i will send you some pictures of it. And by the way, i'm not so good in english too and even i don't know what mesh is ^^
Actually, my bismuth did not become red, it only melted preventing the original silver colour. The only thing that could be is that it is not bismuth maybe, but if you say it is, I trust you.
Because i've tried it too but it doesn't work. I've got the stuff from Acros( Bismuth 99.50%. Powder, 100 mesh) can you tell me if i've got the right one?
I used 99 % bismuth in shavings and only heating it, it melts. But tell me what have you tried and what doesn't work? Melting? maybe the problem is the temperature is not enough high. Please tell me more information.
I don't understand what do you mean with 100 mesh, sorry me i'm not english- speaking.

What metal is the pot made of? Also, are those just regular beer cans?
star0shadows 11 months ago
@star0shadows Probably iron, normal pot, and yes, regular aluminium beer cans.

@Fonserbc Looks relatively easy to do, thanks for the post!

is this the metal used for soldering? they looks quite similar
plokipoiuy 1 year ago
@plokipoiuy Nope. Usually in soldering (if you mean in electronics) it is used the tin. The melting temperature is similar.

@Fonserbc you'll ruin your magnets pouring bismuth on them!
daenumen 1 year ago
@daenumen there are no magnets in this video, and I have not even touched the melted bismuth with any magnet. Don't know what do you mean.
Fonserbc 1 year ago
@Fonserbc oh, it looked like magnets, the silvery metal rings, on a dull metal rectangular plate?
the rings that you poured bismuth into to make those small bismuth pellets?

@daenumen I think the "skin" on the top of the melted layer is an oxide layer-- it forms when the metal melts.
In pure bismuth, though, a thin layer of oxide gives the formed crystals their colors, but you don't want a thick layer for the crystals.

Very interesting video, I like the way the metal changed colours as it cooled and crystalised. What is the music you put in this vid?
resistanceizfutile2 2 years ago
The song is "Tales of Space" from Dom F. Scab from the disc "Morphing synthesizers II" of the group AT-MOOSS.
I'm going to make crystals again, those ones were good, but I'd like betters.
