Plasma Sculptures

BrainAmoeba - 12-10-2020 at 08:33

Hello,

I was living my life, thinking about experiments and looking for inspirations on YouTube. Then I found "plasma sculptures".

Basically, these are noble gases in a glass tube with high voltage passing through it. After seeing that, I've decided to make some research. I found out that other elements may be used (e.g. mercury, or sodium).

Now, questions begin. How do you know what elements will give some glow in these conditions? For example, would bromine give similar results?

How does plasma's temperature affect glass? I've read that these temperatures reach thousands of degrees Celsius. How is glass surviving that?

Thank you for your attention,

The plasma is at very low pressure, so it can be at a very high temperature without affecting the glass. This is how fluorescent lights work.
