I recently purchased some slate, this stuff had obviously been used as when I got home it had some bits of algae on it, another piece had a few brown spots on it and a chunkier piece was kind of goldy(?) coloured through it, I placed all pieces in a basin and added a few kettles worth of boiling water and left it over night, do you think it will be safe to use or ids there anything else I should do?
