Good morning ...and sure i was waiting for the discussions...so we will get even more good ideas...Kenny, the incense Stoic is made out of dusts from,wooden saw dust, dried medicinal leaves,dried medicinal roots and some dried medicinal shrubs...and some added fragrances, like sandal oil, or some oils from flowers.some artificial compounds may also seen. but here we get all sticks from local manufacturers for our temple...so there must be some ashes...that is why i added a flange, by aluminium sheet, in that lid, and you also can see the configuration of the bottle is upside down, why..? yes to dismantle the lid for removing the ashes...but some of the ashes will blows off through the exhaust tube as blower blows towards out...so only a negligible amount of ash is left for...
