Mouthblown protection glass against infrared-radiation with a protective effect integrated into the glass structure itself. Therefore it manages without any coating or externaly applied foils. In the spectral range of 780-1500nm it decreases effectively the thermal load on sensitive surfaces of precious artistic and cultural assets. Historical objects, furniture or room setups if striked by daylight are inevitably exposed to the thermal impact of infrared radiation. The consequences are irreparable material damages in the form of accelerated deterioration and desiccation. A steady temperature change provokes simultaneously expansion and contraction motions in the surface and thereby tensions, fissures and flaking paint layers. The entry of radiation into rooms occur particularly through window openings. Ordinary glass can not provide any protection. The process we developed for manufacturing hand-blown IR protective glass combines knowledge of the melt, components and craftsmanship. In the Lamberts glassworks, as one of the last production facilities in the world, hand-blown glass is still produced using the centuries-old craft technique that has hardly changed to this day. Glassmakers form the viscous glass mass into an elongated glass balloon by turning and blowing on the glassmaker's pipe. Cut open on both sides, the result is a glass cylinder which, when cooled, is cut open lengthways and, after being heated again, is opened and stretched into a flat sheet of glass. Schematic representation of the light transmission of restauro®IR compared to industrially produced float glass without IR-protection.
