Abstract
A smoke producing article comprises preformed granules of a smoke generating material admixed with an inert binder. The granules are compressed at such a pressure and for such a period of time that the granules deform to take up a reduced volume overall but remain separable discrete particles. The smoke generating material is advantageously red phosphorus. The compression is at 2-7 tons/sq. inch (31-110 MPa), and the compression time is 3-10 seconds.
