I'm puzzled.
I dried my 25mm MÜHLE synthetic when it was quite wet. Three times the normal water content. 7.5g rather than the more normal 2.5g
Humidity was around 50%, just like previously, but the temperature was 29C instead of 25C.
The brush was bone dry after 23 hours. The quickest drying time for this brush I have seen so far.
What's going on? The wetter the brush, the quicker it dries? Does a small increase in temperature really make such a big difference?
