Hi
Here's a link to the picture-page of Pirotecnica Boccia, also near Napoli.

There you can see some Stutata- or Fermate-type shells, also with a look inside. The small inserts (Pupadelle) are stacked in rings (Fili). Some, like Boccia here have 7 inserts per ring, some have 8, depending on the size. In our own production here in Germany we use 8, because I believe the spread is a little bit more dense - but I guess that is just a matter of choice and taste. The inserts all have a timefuse (spoletta) and are matched with some strands of bare blackmatch. This way, you can arange the timing, so that everything would go in intervalls or at once. If you would have two "mosaics" of inserts, these would then be called "Intrecci".
As for Pagano's stutatas (the 8'' ones) they have 7 Pupadelle per ring, 3 Fili high. You could make them longer, 4 Fili, 5 Fili, but the spread is not so good anymore. A "Stutata Lampi" is a Stutata with plain flash/salute-inserts, they are also used for daylight shows of course - with the only exception that this would be called "Ripresa" instead of "Intreccio". It is confusing, I know...
These type of shells are very prominent in Italy, but we make them here too because they are my favorite

And in the US there is one manufacturer doing these very nicely with their own touch to it, that's Garden State Fireworks of Millington, New Jersey.
Bye and stay green!
