As I recall (from the UL standard), the tablet is hexamine. I have purchased tablets from: IMS Plus (International Military Surplus) http://www.imsplus.com/ims28.htm I purchased the tablets on-line. My first order was lost, but they sent the second order without charging me for the lost order. > Do you know this test ? No. (Some years ago, I required some means of igniting something. I did some research of the UL standards and found that UL used the hexamine tablet for igniting speaker cloth. Since the tablet was an established source of ignition, I've used it since then whenever I want to test for ignition of some- thing.) > Do you know if this information can be provided by the cloth manufacturer ? You might check to see if the cloth is UL-Recognized. If yes, then the cloth manufacturer submitted the cloth to UL for testing.
