A method of manufacturing a heat insulating/fire retardant material includes forming a reaction mixture by mixing together colloidal silica, a sodium-containing clay and water and allowing the reaction mixture to react for a sufficient time to form the heat insulating/fire retardant material in the form of a gel or emulsion. The reaction mixture may further include a silicon-containing polymer and a suitable dye. The heat insulating/fire retardant material may be used as a heat barrier or heat shield. An artefact (10) includes a body defining a panel encapsulating the heat insulating/fire retardant material, which artefact can be used as a heat barrier or heat shield. |
