CRT artwork possible?

That is sort of true. I tossed a bad tube in the dumpster so that I didn't have to purposely vent it. The phosphorus seemed to "drain" off of the screen afterwards.

I've had this same experience. Snuck one into the dumpster and watched the face change when it hit the neck. Might act differently if it vented slowly.
 
Decent hi res photo of the burn, mounted and framed? Not the same, granted, but safer and less hassle.

Mind you I sound like my dad. That's far too sensible. Someone with more time than me needs to do this!
 
This is a warning to those who try it. Absolutely wear a respirator. Not even just a mask. CRT glass has a fairly large amount of lead in it. And phosphor dust will do all kinds of terrible things to your lungs.
 
Watch the you tube video on CRT repair. score the tube and use a hot wire :)

The phosphor layer is extremely fragile. Any debris that gets on the inside will damage the phosphor.

If you can get the face off the tube w/o damaging the phosphor, I like the idea of triple thick.... it should seal it in. However, if it is a color tube, you'll need to carefully remove the shadow mask as well.

As tubes are not tempered, you should be able to do this, either via mechanical means (cutting), or traditional glass ways.... (scoring and breaking (though in this case, I think you'd have to use a hot wire.... if you can get ahold of a long enough section of nichrome wire and figure out the supply you'd need for that length it would probably be the cleanest way, plus no glass dust from using mechanical cutting/griding).

The mechanical cutting/griding would also litter the inside of the tube, disturbing the phosphors.

It is a very interesting idea. You'll need a clean break (again, the hit wire idea), as otherwise any stress fractures from cutting may lead to cracking just from temperature shifts/shock/etc.

Good luck, it is an interesting idea. I think classic black and white tubes would be best.... like Asteroids.

Good luck.
 
The best way to try and preserve the phosphors and shadow mask is to use a dremel with a grinding carbide bit to drill a small pin hole near the gun assembly in the neck. Then let it slowly reach equilibrium. Using a carbide or diamond disc wheel to score the outside around the glass envelope will probably yield the best results.

Just as others have said, the phosphor material will be easily damaged. Just bumping it will make it come off. I would be curious to see if the phosphor oxidizes once it gets opened to the atmosphere. It might be easier to leave the shadow mask on the glass envelope to keep from disturbing the phosphor coating.
 
I just thought of something. Crts are considered hazardous waste so you can't take it to anyone if you want this done you have to do it yourself. It'd be bad for the company to cut this thing for you.
 
No offense intended, but this sounds like possibly the worst idea ever. Risk > reward.

I'd agree with scoring method and PPE recommendations. I will toss in suggestion for counseling and medication.
 
Get some good lighting and take a decent picture capturing the entire image of the burn-in.

Actually I think multiple pics if these in a grid pattern would probably look pretty sick, with a small caption centered under each screen with the title of the game that left the burn.

Sounds like it needs to be done.
 
Anyways I think when the phosphor hits the air the burn in will fade away anyways.
