That is some really cool wood, IPE or Brazilian walnut, also known as Ironwood because it is so strong you can't drive a nail through it, has the same fire rating as concrete and steel. Ipe has a janka hardness of 3680; in comparison to California Redwood at 420, this hardwood is 8 times the hardness. It's negative though is its dust that can cause a number of respiratory and contact dermatitis allergic reactions in humans.
I haven't yet test the IPE, its not in my hands yet (being shipped down). I'm glad you mentioned it though, I generally do quite a bit of background reading before I start choosing wood for my units. However, I just happened to run across this great wood in a Pennsylvania lumber supplier while I was up north, whether it makes it to final units is unknown at this moment. But from the sounds of it you know what your talking about ( or forgot to cite a website ), and are aware that most if not all wood dust can cause allergic reactions (some maybe more than others?) generally causing reactions to your largest organ, skin followed by the lungs. This is not something so specific to IPE but to all wood dust particles, of even 5 micron in diameter or less. I use high pressure air to blow out all debris from the units several times and assemble them in a separate area, I do my best to contain the natural elements of wood but there is only so much I can humanly control. If you feel as though this might be an allergy problem for you, I wouldn't suggest a wood based vaporizer (just my opinion). Due to even the slightest possibility of the risk, it is likely that I will not offer the IPE, it may just have to turn into an expensive paperweight until a use comes along for it. However, testing will continue!
