PostPosted: Mar 18, 2019 03:10    Post subject: What mineral is this?  

Hi
We've had this mineral in our family for over thirty years and no one has ever sought to find out what it is exactly. From what I've seen on some internet sites, I think it might be Antimony. Can some help it out? The mineral is about 15cm in height.

I think it's hard to tell just by some photos what exactly this is, but you are right: It looks like native antimony ...

Sorry to send you negative news but I am quite confidant that your "mineral" is instead a manmade furnace product. Just what it is I cannot say but I have seen very similar material many times in the past and it does not appear natural. I am sure that another of the Forum folks will be able to offer up a better identification.

You say 'mineral' [singular], but show at least 2 and possibly three different pieces. I too think this is likely a man-made substance. However, photos are never enough and if you want to know what it likely is, you must follow the instructions on the posting page and tell us size, specific gravity [it tells how], hardness [it tells how], and other possible features/properties [magnetism, et al.]. Also, one piece or each piece photographed from all sides especially the bottom which seems suspiciously level would be helpful. Sorry to inform you, I'm doubtful it is natural, but it could be [<5% chance in my opinion].

There is only one piece seen from different views: except the bottom which is completely flat
