Glass sensors. A European study to estimate the effectiveness of protective glazings at different cathedrals
A new integrating method for monitoring the intricate environmental conditions for stained glass windows and their protective glazings is offered by glass sensors based on low durable potassium-calcium silicate glasses with a high sensitivity against corrosive stresses. The easy-to-handle technique is able to detect the comined impact of climatic stresses, pollution, and microbiological effects as well as synergetic interaction. Due to the sensitivity of the glass sensor judgements about corrosive stresses ans furhter damage risks can be made within a few months. The corrosion progress of the sensors isdetermined by infrared spectroscopy and checked by microscopy.
