Actually the way I do it and a traditional way to do it is to lay a few well-lit sticks of incense down (at least 3) horizontal in your incense burner, or if it is a sang vessel then break them in half or however so they fit lying down horizontal, then sprinkle a generous amount of sang powder over the top of these sticks. As long as the sang powder is not too coarse, but indeed more of a powder, the fire of the incense sticks themselves will slowly burn away the heap of powder. Put a little only on the burning tips, then slowly increase the size of the heap towards the back.. then it will increase in intensity in conjunction with the amount needed to burn. Anyway, this is a decent way to do sang at home, as opposed to a real fire in a large vessel. This way you can use a riwo sang cho incense with all the appropriate ingredients, and then just a juniper powder, or the other way around-- a simple incense and a riwo sang cho special powder mix. I prefer not to use charcoal cylinders, the gunpowder is pretty noxious and probably not a great offering. There are little japanese style charcoals without all the gunpowder but they take a bit longer to light.
