Has anyone tried volumetrically dosing directly onto e-mesh and evaporating the solvent before vaping?

I was thinking I could dissolve freebase in ethanol or acetone so that a dose would be a couple drops at most, which should evaporate off quickly, especially if I pulse-fire it at a low wattage first. Has anyone tried this? I'm not sure my $40 mg scale is really accurate enough for me to have the consistency I want for sub-breakthrough trips.

I'm aware that ethanol and acetone are flammable. This would be an extremely small amount and I would heat the mesh at an extremely low wattage to speed up evaporation, if needed.
