Hi Marc, The piece on the righ on the main picture is a piece of slag, probably from an old ironworks, the others I cannot say for sure because the photo of the specimen on the left is not in focus!

I think Spencer is right about the slag.


And it looks like the middle/bottom five stones are variations of SiO2 (quartz).


The rock on the left, without a better photo, appears to be a sort of pegmatitic quartz/mica mixture. There may be some feldspar in there (just as a general principle, I think. Not that you can see any in the photo). Now, if you took that off a piece of a larger formation, then you might find some interesting stuff where it came from.
