Aluminizing

Ok,, where the heck can you still get P4? Someone makes it?

Are these current day images? That’s quite an operation going on. Thanks for the posts.

Possibly LLC Melz?

I believe we have P4 phosphor in inventory at the Early Television Museum. Whether there's still a source for it is another question.

There is a video somewhere ( I tried looking at ETF for it but didn't find it) taken a RACS in France. It shows how they deposited new phosphor. Two different clear solutions are mixed by pouring them into the CRT bottle. The chemicals react and form a white power in the solution,which is allows too settle to the bottom where the screen is. After a while the solution is carefully poured out and the bottle dried.

Thanks for locating the video.
They had some pretty lax safety procedures. Not a very good idea to be smoking while handling chemicals (France of course). Using food containers to mix chemicals (with the labels still on) isn't a wise thing to do either. OSHA would have shut them down in the U.S.

And here's the video done at Hawkeyes here in the United States...
