What is the definition of FlagStone (http://g603.net) ? It seems quite a loose definition incorporating, at least, any buff colored rock used in flooring applications. Is there something more specific than that? What about hardness? Suppose I order a truckload of flagStone (http://g603.net) and (http://maplered.com) get something fairly soft and (http://maplered.com) friable. What then?
