Is this a meteorite?



Sorry if this is a repeat - I'm a new member.


I wonder if anyone could give an opinion on whether this is a meteorite or not?


Found near Reading, Berks, near a reservoir

It is attracted to a magnet

It does not leave any streaks on the underside of a tile

I think its density is 3

It is heavy

It is hard to file, but when done so shows shiny metal flakes


Thank you very much!

    Hi Bracken - welcome!


    It looks like man-made slag based on only the photos but since you have it in your possession please run it through these four websites and let us know what tests it passes or fails.


    First please check the density by giving the weight to nearest gram and estimate the volume by displacement in water (measuring jug) to nearest ml/cc (take the bottom of the meniscus in both cases).  Iron meteorites have a density of 7 to 8 (pure iron 7.9).






    You say it is attracted to a magnet.  Does it act as a magnet in itself? (does it attract a compass needle or a greased needle floating on water?)


    Please also give the exact location so we can check the local geology and industrial history


    Then I can refer it for internal NHM response

    H Bracken - it is not a meteorite.  A thin fusion crust may be formed as it heats up entering the atmosphere, but it would not cause the melting and bubbling as shown in your specimen.

    I also think it's a man made slag.
