And, BTW, to warm up a harp for better function is superflous and
ineffective.It´s superfluous in case of blow reeds because the breath
is warm enough and ineffective in case of draw reeds because the
inhaled cold air immediately balances the warming.

This is true for the steady-state conditions that exist after the harp has been played for a while. While warming is not sufficient to avoid all sticking/popping, it does prevent the condensation that occurs against a plate that starts at much lower than breath temperature. Inside valves on draw reeds rarely stick/pop because the air passing through the draw slots is dry room air and not your moisture-saturated breath.


I recommend a three-remedy belt-and-suspenders solution. It is my experience that warming combined with engraving and waxing the plate surface around the blow-reed slots eliminates sticking/popping. I have described engraving and waxing in previous posts.
