First you need to take a better pic and then you should post it smaller.
If you need help with that, you can PM me

Also, some idea of the nature of the land where you found it.
The more information the better.
Cheers, Mike

lump of Lead

A big blurry lump of slag. Monty

Based on color appears to be lead.

A smaller blurry lump of slag! Just kidding, I have picture problems myself sometimes. But I do think it is a piece of lead slag. M nty

Please post another photo in focus. Could be several things. Pinkish coloration suggests it could be an ore of mercury. Heaviness supports that somewhat. Seems to be frothy surface, like lava or pumice, but photo too out of focus to be sure.

Not lava that I recognize. Pumic is not heavy and basalt is rarely porous.

So, what could it be? Frothy slag from a smelter, perhaps? Is there a history of metal-working or foundaries near where it was found?

Finally, a little story. While using the detector in John Day, Oregon, I found a hot rock: reacting to a metal detector on both discriminate and all-metal mode. Rock is porous like the specimen you show, but darker brown. Took it to Dick Pugh on the chances it might be a meteorite. He glanced at it, did a streak test (scraped the rock on a piece of unglazed tile), and pronounced it ... basalt. Seems a lot of the Columbia River basalt as well as the basalt flows from the Cascade Mountains put out basalt with enough iron in it to make it appear to be metal on a detector. But over millions of years, basalt can form vugs, pits, and weather to a semi-porous state.

Is it attracted to a magnet?

wow you really know your rocks, thanks

Take it to a lapitary (a rock shop) and have it cut in two. Post the cut surfaces. It might still be a meteorite, but perhaps one of the stony-iron types. If so, it certainly would be worth considerable bucks. A lot of meteorites look like, say, weathered limestone. This might be one of them. Try to save any shavings from the rock, as if it is a meteorite, even the shavings have value.
