Mystery glass shard

[Greg G.]

Found this glass shard while strolling the creek side of our house with my morning coffee.  It was partly imbedded in the ground and probably exposed as a result of recent rains and the fact that I raked up a couple decades worth of pine needles not too long ago.

The glass is thick and curved, with remnants of a gray colored coating and a part of a curved red marking that may have been a circle.  From the looks of it, I don't think it was a bottle, my guess it was something automotive.  Any ideas?

Looking at the thickness, the greyed out parts and the red bits, I'd say it used to be a CRT screen of somesort...

Just what I was going to post when it told me there had been another post at the same time, so I reloaded, and there you were guessing the same. I near shard my shorts! Great minds think alike!

 I was about to say a headlight shell, but they aren't that thick usually and they're mirrored too, rather than greyed...

This is what I got when I searched; "CRT screen shard":

It does look like a sealed beam headlight,  usually on items like that when they are silvered they put other coatings on them to protect the silvering.  The sealed joint that shows appears to be from an assembled external envelope for an inner envelope for the filament, etc.

Is the gray coating electrically conductive? That would be a CRT.

I'm thinking someone dumped an old TV.

[HarrySmith]

My thought exactly!  Definitely not a headlight, wrong shape.

Don't know, should I plug it in to an outlet and see what lights up?

[HarrySmith]

No, just put a meter across it.

My other guess is it was part of a sign.  There is a mound overgrown with wild plants and weeds where I found it by the back corner of the lot, not sure why it's there but it's been there for decades.    The house is 100 years old, but my guess is it is simply leftover construction dirt from when the previous owner put in a rockery next to the creek in the early 80s (there's 2 or 3 of the rocks protruding from the mound).  The treasure hunter in me says dig it up and see!

After "reviewing footage" of bare CRTs, I can certainly say it's a piece of a CRT...

Yes, indeed, a small screening pan or table and go for it. But if you do, make sure you have a very good lawyer  at hand. Remember the homeowners in northern California who was just out walking his dog about a year ago?

If not, here's the gist of one story I found quickly about it: "A Northern California couple out walking their dog on their Gold Country property stumbled across a modern-day bonanza: $10 million in rare, mint-condition gold coins buried in the shadow of an old tree. Nearly all of the 1,427 coins, dating from 1847 to 1894, are in uncirculated, mint condition, said David Hall, co-founder of Professional Coin Grading Service of Santa Ana, which recently authenticated them. Although the face value of the gold pieces only adds up to about $27,000, some of them are so rare that coin experts say they could fetch nearly $1 million apiece.
