Hmm... good idea for experiment. Maybe you wanna try and let us know the outcome? But, who can be sure the phenol can vaporized completely with that method? Who is willing to scarified an oven to do that, as if its really works, so then humans who are going to use that oven will be consuming the phenol or not? That's a very 'expensive' way of using cheap pine bedding. Better use better bedding or non pine bedding to avoid harm to animals or maybe humans.
