Cool video the granulating process seems odd…. Maybe it is the right way the way I have understood is you spread it out onto the screen and allow it to dry in the squares of the screen then push it through after it is dry?
I also enjoy this dudes videos. He has a starter video on making Bp
then he made an update using the ‘CIA’ method here and es up with as good or better quality powder than factory stuff.
he has a whole playlist of various experiments he’s done. I get a kick out of learning about this type of stuff. I’m not sure I’m ready to make my own yet, but it’s interesting to watch.
