Okay, that's pretty neat making them out of ceramic. I would love to see the entire process from mold to finished product. I'm guessing the painted the phosphor on to a glass square and then melt/welded it to the ceramic molded tube. I would further guess a similar process was used to attach the electron gun at the back while drawing a vacuum.
I did not know that you could make a tube that way!
