Oven-Drying Wood for Moisture Content Testing

The hotter oven showed the sample to be at approx 7% MC, while the cooler oven showed the sample at approx 6% MC. I am assuming the hot oven to be vaporizing more than just H2O, so the moisture number is questionable. As I observe the samples as they pick up moisture and come to equilibrium, despite stable temp/rh pre- and post-oven drying,
