I look at soaking in the very simple way. Water loosens and softens the skin during first few hours, but after some more time it starts to work as a mild natural solvent and actually starts to destroy and decay the skin. Unless if I would be in some kind of forenzic research team, I don't see any good argument or reason for soaking the skins for prolonged time like few days or even weeks. Few hours to max. a day of soaking will do it's job in most cases.djembefeeling wrote:O.k. guys, now I am interested! What is it that deteriorates the skin after long soaking?
The one instance that was worst in my case, the skin deteriorated so badly that there were some inch wide holes in it. I used to put my skins in a big tub in the garden that was full of rain water, often also had some leaves and stuff in it, just the stuff that gets into a tub in a garden. It wasn't any problem to soak the skins for 3-6 hours, but those 24 hours, yuck.
D.T., what kind of skins require 24 hours of soaking? Are you talking about goat? Because I had thick goat skin, but never required more than 5 hours of soaking.
If the cellular stucture of the skins does not crack, I don't know what really is there that feels so slimy and stinks so bad. My first time of mounting a dunun set it took me three days to get all three duns done. The first overnight skin was fine, the sangban after the second day was uncomfortable, but those two for the duns after three days of soaking were really nasty. They felt slimy and stank so bad that I had the biggest flies I saw in my whole life accompanying my work.
I think a skin can loose a bit of it's fat in water, the warmer the more. And you can see a little film of fat on the water after soaking a skin. But I doubt it's growing after soaking for a longer period of time. Fat and oil don't usually interact with water that much. And how can proteins be set free from the skin if cellular stucture doesn't crack? The proteins are within the cells.
The slimy feeling and the stink, I guess now this is because bacteria settled the skin in big numbers and start to diggest its surface. That would explain all of the experience we collectively had with oversoaking, also that it is useful to change the water once in a while and use clean water to beginn with. I remember the water being heavily chorinated in the US so that might help against bacteria.
That would also explain why prestretching does not result in any of those experiences.
In response to bata: interesting treatment. I learned not to put fat and oils onto a skin, rather play it regularly to put the fat of my hands onto it. When a skin has gotten that dry in the first place, I tend to think it's time has come to be replaced. That improves the sound more effectively, I'd guess.
