One aim of this work was to identify the relevant components in architectural ceramic material, which are responsible for weathering. The existence of reactive and aqueous phases in the low temperature firing model substances and historic architectural ceramic could be qualitatively and quantitatively demonstrated by FTIR Spectroscopy and Simultaneous Thermoanalysis. A further aim of the work was to develop an alternative method for the consolidation of deeply weathered architectural ceramic. After conventional (cold) application of different ethyl silicate systems, the material was heated to increase the long-term stability of the ceramic. A subsequent thermal treatment improves the success rate of the consolidation significantly. The best overall result was achieved with an ethyl silicate oligomer.
