I have seen more damage done to old things in the name of convenience, stupidity and false information. I see it every day. Dirt, itself, acts like a broken shard of glass working its way through substances and a rock is not impervious to damage. Call a stone conservator.....those who do study various chemical effects on stone if you do not believe other's research. I know what the answer will be. It is people like you who, in the name of stubbornness, ruin it for the future. Jan
