I am trying to get a clear picture of the chemical process the lime putty goes through as it ages. My understanding is this...that as the putty ages the water bonds become weak or perhaps the bonds break and water rises to the surface. But if that is the case, then wouldn't we get "fat" putty if we just added less water when we re-hydrated it? Also, how does aging increase the flexibility and elasticity of the putty? Thanks for any and all answers!
