... it has a name I cannot find right now - something like Ariballo or Aborratcho.
Yes, maybe "almorratxa" or "almorrata" according to Newman's
Illustrated Dictionary of Glass. Also referenced in Ivo's book.
But Newman showed a picture of "almorratxa" that is rather different in structure, having a stemmed foot, body with draped rigaree-type decoration and with four "sprinkling spouts" rising from the shoulder of the body. The Kuttrolf of Germany seem to be closer to the source of the "entwined-tube" style like the one Frank shows.
The Spanish versions were apparently made in Catalonia in the 16th to 18th centuries.
