I made yellow salt!
Hi guys I got to visit my lab today.
I recently stumbled upon a video on Periodic videos demonstrating blue salt, but it was not due to the sodium chloride solvation but the solvation of
potassium chloride.
I went ahead and tried it I got yellow salt as mentioned by my text book.
I just used table salt instead of adding some KCl, and heated it until it melted, after that I added a fair amount of sodium metal and heated until
there were yellow sparks visible(unfortunately I can upload that video on SM).
I blocked the top and left it to cool down, I got some solvation and some peroxide.
Sorry For the poor background but I had to do it outside.
What do you guys think, did anyone else try this before.

Water is dangerous if you don't know how to handle it, elemental fluorine (F₂) on the other hand is pretty tame if you know what you are doing.

Sorry The images were large and it didn't upload so I cropped it and uploaded them and one more thing here's the same salt after about 45 minutes.
The red part reacted with water and oxygen and turned into a white mess.

@bnull, when sodium metal is added to molten salt it solvates and forms yellow coloured stuff due to incorporation of electrons into the lattice. This
is due to Metal excess crystal deffect.
Here's the video of periodic videos:

Thank you. A quick search resulted in nothing, so I was wondering what "yellow salt" was.

@Morgan thanks for sharing your findings. I didn't know this phenomenon before(in rock salt).
Water is dangerous if you don't know how to handle it, elemental fluorine (F₂) on the other hand is pretty tame if you know what you are doing.
