I've just gotten into bakoor's. I've tried about ten or so different resins and powders but haven't tried mixing any yet. So far my favorite warm scent is the wax melts called "zen". Fills most of the house too.
Dragon's Blood and White Copal resin is good. Nag Champa powder is decent. I haven't found a mind blower yet though. However i'm sure if i walked into someone else's house that were burning them i'd be amazed. lol
My favorite at the moment is myrrh (I have here guggul in use, Indian myrrh). But I am not burning it, I am roasting! Either I take an old aroma lamp where I replaced the bowl by a tiny copper pot (originally for tealights) or I am preparing charcoal in a censer with a steel filter on top (so I am not placing the myrrh directly on the coal). But charcoal stinks when lit, even if it's non-self-lighting and it doesn't burn that long.
Sometimes I am grounding the myrrh with dried rosebuds or a half tonka bean in the mortar.
It's not just the wonderful smell â€“ the atmosphere in my home has really changed since I am doing this.
In my case, basic and linear almost up to the point of being unimaginative, but, in my opinion, quite natural, comforting and clean-cut: mainly budget incense sticks and essential oils, gravitating almost invariably around the following notes: citrus, especially orange, neroli and tangerine, fir, pine, cedar, vetiver, lavender, marine-ozonic mixes.
