Are these Meteor fragments?

These were found yesterday by a friend of mine using a metal detector. Although they were found with a metal detector they are not attracted to magnets. They weigh a little more than a piece of coal of a similar size. Has anyone has any ideas of what they might be?

Glassy slag

Slag came to my mind also and it is similar to any of these Google Images of Slag

Definitely not meteorites. The surfaces are completely wrong and the density is too low. I'd also vote for slag, although there are other possibilities.

Tectites are another possibility

No, those don't look like tektites. The surfaces are wrong, the banding seen in one is wrong, the density is still wrong. Not sure where these were found, but if the scale Euro implies Europe, the color is wrong as well, as European tektites look like green glass.

No tektites in Ireland, AFAIK.
