I bought some musk root from Dan at Apothecary's Garden ages ago but didn't get around to grinding it until today. I just tried a trail-burn of 20% musk root and 80% Australian sandalwood from @TheWorldMakesScents . All I can say is wow. I've been testing out some different roots lately (orris, turkey rhubarb, and I have some calamus to try) — this is the best result so far! I'm keen to experiment more with it, as I'd used ambrette seeds in the past and noticed they do slowly go rancid over time. Maybe this is something that wouldn't happen if they were locked away from oxygen in incense sticks, but it's also something I'd rather not have to consider.
