I really like cork bark for a basking area (all my turtles have pieces to bask on). Over time, however, it will get saturated to the point that it will need to be replaced (you can dry it out, but it will not be restored to its former condition---it will become waterlogged fairly quickly and will need to be redried). Wedging it between the sides of the tank would lkely increase it's longevity. It won't "dissolve" per se, but as it ages you'll probably start finding a few small pieces on the bottom of the tank.
