I know you won't see this, but having a piece of history is pretty cool and I thank you for it.

The sample is Bastnaesite from the Birthday Claim at the Mountain Pass mine. Europium was refined from this material, and made red phosphors for televisions. If you watched a TV, you probably saw something that had material from that mine in it.

If you do happen to read this, please let us know how you're doing. Drop me a postcard at the address I gave you or whatever you like.

Some info on the sample, edited for brevity

I went ahead and removed the link to the website that hosted it. It doesn't need to be here, I give it to select persons.
