I've turned a fair amount of alumilite pens and there isn't any odor. Is your bowl a hybrid wood / alumilite casting? Maybe you're smelling the wood? I suppose the other possibility is that there are a number of alumilite products available; the alumilite clear and alumilite clear slow that I use don't smell much at all, but perhaps some of their other resins (like many resins on the market) have a pronounced odor. If that is the case, I don't know how long they smell but double check that you followed instructions carefully because any error in resin:hardener ratio could lead to partially uncured resin containing smelly volatiles.
