I tried heating one of my tubes with this shiny interior coating, and it would not turn to gas. The pressure inside a nixie is fairly low, so I thought that if this was mercury, it should have boiled-off, but it didn't. Perhaps it is a different metal; I'm not going to break it open to find out.
On a similar note, I have some tubes with a black interior coating that wont budge with heat. But, I did watch one of my 6091's at normal operating temperature with grayish internal deposits and saw the metal, presumably mercury, slowly evaporate. It probably condensed elsewhere. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
