Default Close Up - Whatsit?? Glass Telegraph Insulator!



This is too easy, but I'll give you a clue anyhow. What's my main hobby? Now go back in time. Think what used to line the railroad tracks. Aaaah, I've given it away.
------------------------------------------------------------------------
EDIT:
This was not a guessing game and I made it one. There's a note of appology down the thread a bit but the error needs to be corrected here in the original post.

The item is a glass insulator of the type used for telegraph and telephone lines. You used to see lines with thousands of these insulators running beside the railroad tracks. The shot was taken through the dome of the insulator and the lines are reflections of the interior threads. There is also more info on this in later messages.
-----------------------------------------------------------------------------
Picture info:
f = 3.2, s = 1/30, FL = 63mm (35 mm equiv) macro focus, W/B = tungsten, lighting = 100w goose neck lamp, downsized to 640x480

Here's a full view of the insulator from the same vantage point but not so close. It looks quite different. This one is reduced down to 320 x 240

Not metal but it was indeed molten before it was poured into a mold and allowed to harden.

No water - It's as dry as a bone and nearly as hard as a rock.

Boy, I don't know either. Molten lead? Surely not silver (expensive to line) but it sure looks like it. No idea the item.

It's an old glass insulator either for phone or power off of a utility pole.

Exactly!

Here's a picture of one in service:


Literally millions of these things were made in the mid 19th to mid 20th centuries. You used to see miles of telegraph lines running along the railroad tracks. They come in many sizes, shapes and colors. This one is a pretty common one made by Whitehall Tatum in the 1920's or 1930's. It came from the line that runs through Brookneal, VA. The shot was taken through the dome of the insulator. The lines are the reflections of the interior screw threads. Lots of folks collect these things. The rare and exotic ones can go for big money. This is a $3.00 one that makes a pretty good paper weight.
