All morta is bog oak, but not all bog oak is morta.
True morta comes from a well-defined specific area in France, and cannot be exported in raw form. Finished pipes made from it in French shops are durable and suitable as a pipe material.
Bog oak can---and does---come from anywhere on Earth a partially-fossilized submerged oak tree in a swamp is found. It might NOT be durable and suitable as a pipe material. (It's a crap shoot)
A large majority of the pipemakers I know and have worked with over the years gave up on it after using it several times. Too splintery, too fragile overall regarding impacts, and prone to charring/burning.
As for banding the bowl in the pic, the shape would be impossible to clamp in any practical sense. (A master silversmith could probably "cage" it given 15-20 hours with no limit on the amount of silver used, but that would just be silly.)
