Abstract:
1. A process for the production of a sealed insulating glass unit comprising two glass sheets held apart by a spacer disposed about a periphery of the glass sheets with the spacer and the glass sheets defining a void space filled with gas, optionally with a sealant between the edges of the glass sheets outside the spacer, characterised in that the insulating glass unit contains an electronic device, having information relating to the origin of the insulating glass unit, manufacture of the insulating glass unit, properties of the insulating glass unit, or a combination thereof, and which is designed to be read from the device by means actuated from outside the insulating glass unit, the process comprising: (i) embedding the device in a molten spacer; (ii) applying the molten spacer onto a first of the two glass sheets; and (iii) assembling the first of the two glass sheets with the second of the two glass sheets so that the molten spacer is pressed against the first and the second glass sheets and bonds the first and the second glass sheets together, wherein the device is embedded within the spacer and concealed within the insulating glass unit.
