This post #66. Myth #7 proposes an opinion, that one does not need a stand to dry a brush properly. The OP states:
according to my own observation and not based on any scientific method, my personal opinion . Thats cool, we all have opinions and he later states I encourage the membership to conduct their own experiments to refute existing data. Without said refutation, what's available stands on its own, and those disagreeing with the validity of the data is just so much sour grapes.
Good idea. I have little faith in opinions as we all have them. Lets see some facts. so lets test this, but not to refute opinion because opinion is subjective. Im not even sure why this matters. The brush is going to get wet again anyway so what is the point of ensuring its dry before using it again? But, lets assume the premise is correct, that is, to ensure long brush life, one wants the brush to dry quickly. The basis of this might be not to get water into the knot as it might affect glue longevity. If you dont care about brush life, none of this is of interest. If you do care, then lets look further.
To be perfectly clear, one set of data points is absolutely meaningless. We would need a large set of data and within each experiment, lots of data points across drying time. And then we dont know if different brush brands and sizes matter. But I got what I got, a single, cheap best badger Edwin Jagger thats sold a dime a dozen on Amazon.
The brush weighs 48g dry. Post #69 is correct. Edwin Jagger printing is such that its read upright with the brush inverted. Does that have meaning? Is the company sending its consumers a message?
Soaked and full wet the brush weighed 72g. It was then used, washed clean, and shaken dry to 54g. At that point I weighed the brush periodically throughout the day, albeit at different times but that doesn't really matter due to how the brush dries. I did this both inverted in its stand and the next day stored upright. Conditions were identical, stored in the bathroom, in the open, either in the stand or next to the stand upright.
I suspect there are a huge amount of variables affected experimentation, the most obvious being ambient humidity. During the day it will be higher than at nighttime when the ambient temperature drops and humidity drops. I have observed that in the early Fall, the brush NEVER dried in 24 hours but as the temperature has dropped, it does dry in 24 hours. Since I observe the house humidity, I know for a fact its lower than several months ago. I also suspect that Heisenberg might even have an effect as the mere act of moving the brush onto the scale might dislodge water. But it is what I got and its better than nothing. The results follow and are normalized on the timeline (i.e., I set the graph times to be identical even though they were different days and times in the morning)
It would seem that if one is interested in water soaking into the knot, then the area under the curve is what matters (much like a torque curve for a car engine).
The results are interesting. The standing brush stood for hours longer with 2gs of water than hanging. Considering the scales here, I do not believe that insignificant. Something is going on there. Was the water sitting in that knot and not evaporating? Yet, after that long initial drying period, the standing brush moved down to the second level quicker and the last level to dry at least two hours quicker. To be clear, the hanging brush dried sometime after midnight so thats a guess.
What can I conclude other than I wish there were more data points over the 24 hours? In terms of area under the curves, Ill guess its a wash, that is, they are equal. Although just from the graphs, the area under the curve for the standing brush looks larger, I dont know the exact time the hanging brush dried so its fair enough to say equal. The only thing of significance I can see is the heavier concentration of water sitting longer on the knot by standing on end. Does this mean anything? I have no idea. But I also find it interesting that the standing brush, overall, dried quicker.
I consider this one simple test inconclusive but the fact it took a lot longer to dry some water out of the knot while standing significant. I'm not sure that actually means anything as in a heavier amount of water pushing down into the knot.
Ill get a different brush and run the same test in the future.

In a couple of weeks, I'll try this again using a heavier brush and see what happens.
