Still think it is some form of slag or ore...the fact it has those vesicles and surface texture pretty much rules it out as a meteorite...if you still think we are wrong then you need to test it for nickel...it has to have nickel in to be an iron meteorite...second test is to polish a section with shiny metal in and etch it to see if it has a widmanstatten pattern...lots of info on how to do this by googling it....if you find these things then we can follow it up further with tests at a recommended University.
Let us know how you get on or if you need any more help.
Cheers.
