I thought it was a piece of stone tile but my Garrett pinpointer thinks otherwise.

Short and sweet.

Object feels, looks, sounds like stoneware of some sort. However, it "sparkles" and sets off my pinpointer. Very lightweight (no scale in this range but about as heavy as two ink pens). Object is broken on both lengthwise ends, but measures about 1.5 - 2.0 inches wide and about 0.25 inches thick. It has an irregular hexagonal shape. I believe it is made of a composite material of some sort, and would have guessed it was some sort of pocket sharpening stone if not for the weird triangular sides. Found in a field, probably got plowed at least once. Site usually produces finds from 1890 - 1910, but ranges from 1870 - 1970 or so. Midwest.

Because it is black, it doesn't photograph well. I did my best. Bad magnifying glass work at the end.

Sounds a lot like graphite (carbon). Can you write on a piece of paper with it?

Here's a trick I learned. To photograph black objects, put it on a black background. Your camera is picking up the white background and stopping down the lens making the black object even darker. Gary

Maybe a wild guess...
Depending on your location, any chance this might be a tile off the ill-fated Space Shuttle Columbia that burned up on re-entry?
If I recall, the debris field was quite extensive, and a lightweight, heat-resistant tile should be expected to survive the descent.

Interesting guess! Pencil test is negatory, however:

An excellent suggestion. Here are the resuts:

Ah now it would of course be awesome if it was space junk.. but no, found in Iowa so nowhere near the debris field.

For what it's worth, which is not much, my White's TreasureMaster is assigning it a VDI of 02 and puts it in the range of "Foil" (between "Iron" and "Nickel"). The object is not at all magnetic.

It also just now occurred to me that if this were a tile from the Space Shuttle, it would probably have a serial number on it.

Definitely from a U.F.O.

I think I see... "MADE IN SPACE" on the one end... not sure.

:P

We had a whetstone that we put in the 20 man life raft accessory kit that was kind wedge shape with seems. I'll see if I can find a photo of one.
