I am aiming to keep the humidity more or less stable in a closed chamber.
Therefore I am using a saturated salt solution in a closed chamber for that experiment.
What bugs me is, that I always end up with salts growing up on the inner faces of the vessel where I put the solution in.
The salt is, btw, growing even above the initial fill level. So the evaporation seems no to be the only reason. I guess this is related somehow to the capillary effect?
Is there a way to easily prevent this
