You might be able to use this as a koudou cup, but every koudou cup I've ever seen has a very distinctive shape and dimensions. For example, the sides are usually straight, not curved in at the top; nor have I never seen one with a lid. (There is a type of koudou implement that has an openwork silver lid, but it's used purely for heating the charcoal prior to use.)
I still
think (not 100% sure) that this is intended for burning commercial pressed incense rather than "listening" to heated aloeswood chips; but having said that, Olivier can always give the koudou approach a try. It's my favourite way of enjoying incense, in fact.
If I recall correctly (because it's been a while), I bought my aloeswood chips from
Essence of the Ages. The owner, Beth, also sells a full range of koudou accessories, including the ash, bamboo charcoal, and sets of utensils. (Warning: this hobby can sop up a lot of your cash!)
BTW, I spell it
koudou and not
kodo because (1) both O-s are long, and (2) most people who talk about kodo are talking about Japanese kodo drumming, which is a different beast
