For agarwood poweder, it would produce 2 different aromas if you heat them differently:
1) Light directly as an incense
Looking good with the lid close
Use a thin layer of ashes as base, and a bit of agarwood powder in a short straw (around 0.5g). Use chopstick to push the powder out and you would have a lovely cylinder shape incense to start
The aroma quickly releases and within 2 minutes, a small room will be filled. A light burning note is noticed.
2) Heat on an electric burner
1 small scoop (0.5g) of agarwood powder on the metal plate of the electric burner
Personally, I think this is a better method as the aroma last much longer, the scent contains minimum burn node, sweeter and warmer. Once all resin vapourise, the brownish colour will turn black, indicates it is time to change the powder.
