I thought about that method, my ideal way of burning incense sticks is using a coffin style incense holder with flame retardant cotton, so when sticks like Dreams of Fragrant Harbour or Dr. Incense Sinking Tarakan don't stay lit laying down, I use a normal holder which keeps them at a slant. This usually works better, more air circulating perhaps and ash falling away, though Dreams of Fragrant Harbour still requires several re lights but it'll stay lit for a good couple of minutes.
However with the Sinking Jayapura, it'll stay lit for perhaps a minute at most, and it's not really the ash which is suffocating it, which I assume is the principle those upside holders work off of, but I'll still give it a shot and see how they fair. In terms of scent, I like them but I would still rather light up a stick of Dreams of Hai-Nan or even better a stick of Dr Incense Enlightenment 🤤
Really hope you enjoy them! They're quite different from the profile I usually enjoy which are minty, airy sorts of sticks, but there's a resinous meatiness to them, reminds of that note in Habz's Oud Chachak, it's not immediately appetizing but something about it continually draws you in, addictively so. Perhaps there's even the slightest hint of pepper and an animalic tinge which's got a hold of me.
