Abstract:
1. A marker system for applying to surfaces of items, articles, goods, vehicles and/or premises, said marker system comprising: a marker comprising a temperature resilient medium, the marker having i) an aqueous polymer emulsion capable of securing the marker system onto a surface, ii) a predefined carbonisation temperature, wherein the temperature resilient medium includes an inorganic matrix having a predefined fusing point lower than the predefined carbonisation temperature of the temperature resilient medium, and iii) a fingerprint configured to distinguish one marker system from another and to identify a source of an item to which the marker is applied; the inorganic matrix configured to, in response to being subjected to temperatures above the predefined carbonisation temperature of the medium, fuse to the marker to form an adhesive protective layer thereby encapsulating the marker onto said surface.
