The Marble Institute of America's technical office fields a wide variety of calls. A review of the call log will show that several topics reoccur with alarming frequency. One of the most common conversations starts like this: “Hi, I work for a stone fabricator, and a local architect is wishing to specify one of our inventoried materials for a small commercial application. He is asking us to provide some information on the stone material. He mentioned something about an ASTM standard and listed a bunch of numbers. I've been working here for years, and this is the first time I've ever heard of this stuff. Do you have this information for this stone? Where can I go to find it?â€
