How do they make Canister shells without pasting?

[Stef727]

I have seen a lot of photos/videos (especially maltese and italian) where they make can shells without pasting, just string.

 

I'm assuming it's done this way to save time and the big mess that wheat paste creates etc.

 

So how do they do it?? do they use a special fire resistant string or do they protect the string with something later?

The method is called "rinfasciature", and is an old Italian time-saver for prepping large shows.

 

There's nothing magic in the process. Ordinary paper and spiking twine are used normally. However, tarred string is easier to make hold without slipping. One simply rubs some asphalt tar on the string as it's dispensed. The 'sealing' that would normally be obtained by pasting is effected by the way the paper is overlapped and folded.

 

There's a decent write-up of it at the end of the Fulcanelli section of Pyrotechnica XI, and there are a few good articles out there concerning it, written mostly by Mike Swisher.

So the "asphalt tar" also protects the string from the fire??

 

Btw Thanks for the Pyrotechnica IX info, really good information! Would recommend it to everyone.

No... the tar just helps prevent the twine from slipping while spiking.

 

Nothing is used to protect the spiking except a tight over-wrap of kraft paper. The more desirable Italian flax twine is quite resistant to fire. Cotton is a little less-so, but still will survive the lift on single-breaks, when protected by that over-wrapping.

 

Understand that among practitioners of rinfasciature, some DO paste the string (only, but not the paper). Some use the tar.

 

Oh, and I mistyped the issue number of PT ... it's in XI, not IX.
