I’m using thermo isolating stainless tea-pot as a top load on my coil and I think I’m not alone. It has the advantages in accessibility (every store with kitchen stuff), the total surface is much bigger than the occupied space and it looks esthetically good.
But, these pots are in fact Devars jars – it means two layers of metal isolated by vacuum. My warning and also a question is whether the vacuum and high voltage cannot produce X-rays in this configuration. I rather made a small hole into my top load to release the vacuum and I recommend the other users to do the same…

I don't think it would be a problem since its made of metal. If it was glass then that might be a problem.
I operate 150KV 15mA X-ray machine at work and it uses 1,5mm thick plates of copper as a filter for removing the low energy photons! The plate of stainless steel the tea-pot is made of cannot stop high energy photons in case they are really produced.
Honestly, I also think it is harmless. However I can not measure it so I'm rather double sure and released the vacuum...

Have you guys tried to Google ''Faraday cage''? :p
What? Are you replying the right thread? What has a faraday cage to do with a possible X-ray radiation??? X- rays are photons, only thick layer of high density material can stop them...

I didn't know they were photons but i guess that makes sense. After all when you go and get x rays it creates a picture on the film so i guess it would have to be photons and they also shield you with thick lead and not a piece of foil or something.

I think what Marko is trying to say is that because the pot will act as a faraday cage, there won't be any potential difference inside the pot, so no x-rays will be produced.

That’s interesting with the faraday cage concept… Sorry to Marco I did not get it. But still I do not think there can’t be any difference in potentials on top-load like the tee pot is…. I made a small scheme where I’m showing why I think there could be a difference and why the electrons could go through the vacuum.
Once the break out starts, there must be temporary charge depletion in the closest vicinity of the break-out point. The question is which way the electrons choose for the flow…
