Can I use the cupelation method for raising the purity of a copper-palladium alloy? Thank you. The alloy comes from mlcc's. It is about 40% Pd some 50% copper and other "junk".
Good work sir! I like your idea of Portland cement in a steel can! I was wondering why your Cupel didn’t break when you pried out the Pure Silver! Good idea using a can to hold the Portland cement. Thanks ✌️PT
Since nothing is explained in this video, I will "assume" that you put sterling silver in portland cement and the lead oxidized, leaving just the silver.
@@MrAllan9 that was in the very beginning when I knew little about refining and nothing about video editing anyway I was very satisfied with the purity of the silver combined with the availability and low price of the equipment required so I decided to share the video

Not really, you'll make a bigger mess
Thank you for the swift reply!

Is it helium tank furnace? I have simmilar helium tank, I want to build funace, is it OK?
yup
@@OwlTech333 Thanks :-)
it seems like you have a heatsink on your burner, what is it?
To compensate for the poor design of the torch it was heating too much
Could you wiggle the camera more please?
Спасибо за видео, можете подсказать, как вы делаете капели?

Exactly what happened
How much lead per 10 grams of alloy?
@@OwlTech333 can i use tin instead of lead since there are lead inside tin?
@@OfficiallyRetired no, because the tin creates a refractory oxide layer on top of the melt wich protects the other metals from oxidation
@@OwlTech333 what is something else i can use to sub out lead? I'm having difficulty to find some lead right now
those little beads that form around the edges of the button...what are they?
silver beads. If there is moisture in the cement sometimes the metal spits out
have you done gold with the cement powder?
yes but alloyed with silver
awesome thanks for the info.
So what haopened exactly you oxidized the lead away?? That why it sulidified so quickly
Yes there is only silver left at the end
Will this work for platinum/iridium???
Yes for platinum not sure about iridium
how do you know the reaction is complete? i mean know all the lead and base metals are absorbed into the cupel?
do you see the rainbow at 3:02 on the surface that means the reaction is complete, it is preceded by the "flash" - the molten metal becomes bright red
you can see the flash here th-cam.com/video/OyOzfP-JAI4/w-d-xo.html at 12:04

Do you have silver nitrate stains all over your hands don't you wear gloves
actually I don't' have stains anymore because I've started wearing gloves
Ten minutes of no sound or explanation .......

Thank you!
The beginning video is a waste of time, I'm out.
Sorry for wasting your time
@@OwlTech333 I watched most of your videos, but why would you put a couple minutes of wasted video with that opera music?

@@OwlTech333 I appreciate your videos, and am a subscriber, sorry if I offended you, just a bit impatient on my part.
@@MrAllan9 no offence taken mate :)
