Silver Thermite welding powder.
'eesa found some Thermite powder at a construction site 'e was on once.
It was used to join copper straps that formed the earth that the buildings & machinery used.
Yesterday, while mucking around with some magnesium shavings & iron oxide 'e decided to lightup a thermite charge.
Theres 10 charges in the packet.
It was spilled out on concrete & lit, pretty & messy.
But later on 'e decided to cleanit up & there were big chunks of silver in the ash.
Should 'e just dump the lot in a crucible & spark it up?
Whats the silver (if its pure) worth?
Or should 'e make some sort of carbon mold & use that to make a casting?

Re: Silver Thermite welding powder.
Not silver, zinc/chromium.
High end thermite, carcinogenic too, so watch out with that stuff.

Re: Silver Thermite welding powder.
Actually I don't, to be honest, I'm not even sure I know where I got that from, haven't been reading into thermites for a long time.

Re: Silver Thermite welding powder.
OP, I must say that your references to yourself with " e' " are most annoying. Please stop this immediately.

Re: Silver Thermite welding powder.
OK swIm'll stop the 'e thing.
Its how swIm thinks, that translates into how it is said.
ie, he & she & we are all said as " 'e " the result is sorta like using the word 'SwIm', it has multiple meanings but the end result is the same.
It turned out there was only 8 of the thermite mixtures, they weigh 90gms each & swIm has set off 2 of them.
They are labeled "CadWeld 90gm"
The matchbox sized ingot that resulted looks like silver, quite weighty.
Silver solder it whats used to join copper pipe together so I expect its silver here too.
But now I remember there were other bags of the same thing around where the Cadweld packets were.
There were plain thick plastic bags & weighed about 6-10Kgs each.
Each bag had a 'Starter' packet that was to be poured on top of the mixture, each starter was the same size as the 90gm packet....
So each large bag probably contained say 3Kg -> 7Kg silver!
Gee wished I clicked to that earlyer.......
This site is exactly what I had.

Edit, after reading more its is probably a Copper-Aluminium mixture, not silver at all.

Re: Silver Thermite welding powder.
And using "swim" is retarded and won't protect you in case anything you posted on the webbernets ever got pulled as evidence against you. Not that anyone would care enough about you stealing some thermite to go searching totse for posts you may have made.
