ABSTRACT:
A shock tube initiator comprises a plastics tubing having an unobstructed axial bore, said tubing having throughout its length an inner surface upon which unconsolidated reactive materials are provided as a loosely adherent dusting of shock-dislodgeable particles at a core loading sufficiently low to avoid rupture of the tubing in use, wherein said reactive materials comprise flake metallic fuel particles having a surface colouring layer of pigment, e.g. Fe.sub.2 O.sub.3 whereby on firing of the core charge the residue is visibly of a different colour, hue, or shade.
