Expensive, but oh so cool and reusable/impervious to light/hold the cold well.
I did bottle 2 specialties in ceramic at my last position. They looked cool, but are tough to get filled just right when you can't see what's going on. We (operative word here, as I had the bottling guy do it - sorry paul!) only bottled off a single head, manual filler. First run of a barleywine he did 400 bottles and second run of a wheatwine, he did 300 or so.
Get the swing tops - it's tough to get a cap to stick just right.
You're looking for MKM Ceramics out of Germany for a supplier - I picked mine up in Canada from Phoenix Packaging. The delivery time was long as the bottles came over from Germany.
