Charcoal stars bound without dextrin

Recommended Posts

Hello Pyros,

 

here a vid from my last firework, the shells at 0:20 contains willow & gold strobe stars with a high amount of charcoal, bound without dextrin.

The rolled stars have a maximum drying time of 24 Hours, the solvent is plain alcohol.

 

 

And in this video, the shells from the beginnig up to 1:32 contains also only charcoal stars, bound without dextrin.

 

 

Greetings

Stefan

I hope you can answer a few questions about your experiences with PVB. I'm quite interested in trying it.

 

1) Do you see any change in burn rate with PVB instead of dextrin?

2) Have you experimented with any cross linking of the PVB for stronger binding?

3) Have you observed any oscillatory burning characteristics in compositions bound by PVB?

4) What type of PVB is it that you use?

 

Thank you
