well actually, My dad told me playground sand would rot if I used it, same with sand from the beach or stuffs.
For something to 'rot' it needs to have organic matter, 'rotting' is what we call bacteria breaking stuff down, like an old piece of fruit. Sand doesn't have any organic component, so it can't rot. It is possible that there are some organics trapped in the sand if you pick it up in the wild, but proper sifting and rinsing can eliminate these. Sand purchaced from distributors like landscapers, sandblasters, quarries has already been rinsed and sifted to a particular mesh size, so no organics, no rot.Yo_Loach said:well actually, My dad told me playground sand would rot if I used it, same with sand from the beach or stuffs.
