Hi, I've opened a thread at misc. part but I guess that it's better to ask to luthiers who are familiar with the subject Here is the link for the opened thread click My question is: I'd like to learn what is risky with the spalted maple dust? I've read that it may cause problems in the lungs but what it really does? How big is the risk? Is it the same risk if the lumber is well dried in kiln? I ask it because I've respired a little bit of it and wonder now if I'll have any trouble and what I should do to prevent it.. I wonder if I inhaled fungus, what can happen?It's bad but how bad? Will it cause an allergic reaction, make me caugh for some time or will it ruin the lungs? OK maybe the right thing is to ask to a doctor but if there are some TB'ers who know how serious is the risk, I'd be grateful to hear them before. I don't want to go immediately to the doctor if it's just some caughs and it goes. I insist on it because there's a bass that I'll have soon with a spalted maple top and I didn't like the finish that the luthier used, we decided to change it and to do so after moving the finish he used a machine with sandpaper to move all the remaining finish and while doing this I was with him and everywhere was dusty. I think I inhaled it and now I fear if it's too serious for my lungs..
