Hello!
In this video I'll be melting pure palladium-black into a shiny button, using a oxy-propane torch.
Conversion of the yellow salt to palladium black is the final stage of a lengthy refining process.
Here I'm adding sodium hydroxide flakes to a prepared in advance beaker, containing the
yellow palladium salt and little formic acid.
The conversion is almost instant.
This is NOT, how you should measure temperature.
A good swirl and boiling for 10 minutes and we are done.
Here comes my favorite part: harvesting the black caviar
After rinsing with plenty of water
For the melt I used brand new melting dish with added borax.
After squeezing out and decanting most of the water, I started heating the filter paper
while seasoning with more borax
The goal is to slowly burn off the filter paper while sintering the palladium black,
into a compact mass.
After burning the paper, I turned up the heat
Right after removing the flame I covered the button with borax
After boiling the button in hydrochloric acid to remove the excess borax, it's time to weigh it
Thanks for watching!
