Thank you Shawn, you are right, one closer inspection it is indeed
terracotta. I used my microscope to look at it in more detail and I am able to see some surface within one of the entrance holes that gives it away. I should probably have understood this from the
weight that ought to have been somewhat larger. The
patina looks quite nice and if it is a
fake someone did a
good job trying to make it look old. I am
still suspisious though, are objects ever found with this kind of
patina?
Cheers, Jan
