Why is it essential that smears be air-dried before heating the slide and why cannot they be gently heated over a flame to speed up the drying process?

Any heat much over room temperature at that point would denature the cells due to the water content on the slide. Even if it was gentle, the heat from the flame would be enough to sizzle them like tiny fried eggs. :)
