I haven't gotten around to what the composition of the tube might or might not be. No one but a Belgium exporter or some associated Belgian exporter/importer would have reason to apply a trademark w/ protection in/for the country of Belgium.

Centrifuging metal is a bit of a joke, but if you can make something from centrifuging molten metal I'm sure you can break something by centrifuging molten metal. I'll get back to you on the component comparison.
