I don't know much about Bakoor or making any sort of Joss stick or incense; but I do know that the right solvent it vital. No DPG. You need something that will burn well, and not attract water. As to which fragrance materials work the best, guess you will have to experiment. Why not try using the wood chips you can buy where you get stuff for the barbecue? Indeed I have seen incense burners using charcoal rather than wood. Sorry that I can't be more helpful.
