Cleaning the inside of a CRT?

Hello all!

At work, there was an old computer monitor kicking around without its
casing. It got shoved and moved around until the CRT socket board hit
the table the wrong way and broke off the end of the tube. All of the
metal bits (electron guns, filament, etc) came out with the bit of
glass around the pins, so now I have the circuit boards in the salvage
pile and this funny-shaped glass bottle on my desk. (It still has the
metal band around the front rim.)

It occurs to me that it might be amusing to make a beer glass out of
this thing. However, I don't think that CRT phosphors and the aquadag
on the inside are part of the four basic food groups. I've thought of
three ways to deal with this problem.

1. Erosion - put a handful of sand, rocks, or bolts in the tube and
shake it around to abrade the phospors and conductive coating. Then
rinse well.

2. Corrosion - put in a mild acid or other chemical that will dissolve
the unwanted material. Then rinse well.

3. Sealing - pour in some food-safe coating and slosh it around to coat
the entire inside of the glass, covering up the phosphors etc.

I realize that if I want to drink out of the neck, I won't be able to
fill it more than about halfway, so that there will be an air gap above
the beer when I try to drink from it. I guess I could punch out the
anode connector to make an air hole, or just drink from a long straw.
Also I'll have to polish the edges of the neck glass where the base
broke off.

Has anybody tried doing this before? What worked or didn't work? Is
this a bad idea for some reason I haven't thought of?

Thanks!

DUDE! There are much better containers for drinking the liquid of the
gods! You have to have ample head space, and an opening large enough
to be able to enjoy the "nose" of the beer before pulling a long
draft. Suggest you go to www.beeradvocate.com to check out the styles
of beers, and what kind of glass they are best enjoyed from (and what
foods they go best with) ...

Cheers!
 
Perhaps instead of cleaning it out, you could enamel the inside of it
with a black or clear material that would protect your beer (and your
body) from the chemistry of the tube but allow you to show off its
construction.

Just when you think you've heard everything...

I wouldn't recommend doing this at all.

I wouldn't do it. The phosphors are very poisonous, and there's a
lot of lead in the glass.

If it is a Color tube then there is a metal plate inside. If it is a
black and white or green
tube then you can "probably" dissolve the phosphor.

In any case I wouldn't drink out of it.

Good luck and let us know if you die.

There are too many power toxic materials involved in the CRT manufacturing.
This would be taking too much of a chance to determine yourself if the glass
surfaces are safe for what you want to do. The glass itself has a very high
content of lead in it. This type of glass was not classified to hold food or
drink for consumption.

Your best bet is to dispose of the set, and forget about your idea.

If you know a good glass blower, you can have them make for you an imitation
drinking glass of a CRT. This way it will be safe for you to use.

I have to admit... I have read all types in these groups! This one is saved
for my books.

There has been also tons of lead around water in the water pipes for more
than 2000 years before men rang the bell !

Get a yard glass...drinking will kill a person well enough without
giving it a "head" start.

True, and adding the CRT's phosphors into the mix,
might just give him that extra little requirement to win
this years Darwin Award for originality !!!

There is one and only one accepted way, approved by the bdsma
(beer-drinking stupid mo'frs association), to clean the inside of a
monitor:

Or not. I didn't think of the aperture grill / shadow mask in the front -
that would make it hard to either erode or corrode phospors, or get them
completely coated with some sealant. It seems that the stuff on the
inside of the tube is fairly nasty.

I did think of one thing that would work - find or make a long glass
"test tube" with an outside diameter just a bit smaller than the inside
diameter of the neck of the CRT. Then pour the beer into the test tube,
conceal the tube neck/test tube lip with tape or something, and drink
from the test tube. The beer would never touch the inside of the CRT -
it would all be in the test tube. It wouldn't hold a useful amount of
beer this way, and it would be obvious on close inspection what was
going on, but it might be good for a laugh. For extra points I can put
the yoke back on the CRT and connect it to a box with blinky lights and
pots and switches and claim that by sending different waveforms through
the yoke I can make the beer taste different.

I will be sure to let you all know if I die trying this.

I have heard of alot of strange things in my life but never ever thought
of drinking beer or anything far as that goes out of a broken picture
tube . Why cant you use a glass ?
