Mark, Zeolites are useful in reducing odor and pollutants in exhibit casework. I would worry more about what else may be in the product and also in how it would be used within a room. Ask the salesperson for any technical information on the product (especially what's in it). Often an MSDS sheet (required by law) often gives insight into the material. This is also only a first step - as many of you who work with conservators know - we will do outgassing testing of new materials that are intended for exhibits and collections spaces to see if they may present a problem. If you have a conservator or consult with one this is something you should run by them. Cheers! Dave David Harvey Conservator Los Angeles, California On 8/23/06, Mark D.
