Cultural heritage that consists of porous calcium carbonate minerals suffers many detrimental influences leading to material loss and structural decohesion. Nanolimes have emerged as a new source of tools for its preservation as an improvement upon traditional techniques. While their modes of action have been investigated on surfaces and consolidation depth via time-delayed destructive methods like microdrilling, immediate real time observation and investigation of these processes inside confined pore spaces haven’t been reported.<br/>We have developed a first prototype of a pore-imitating micro-comb test system (MCTS) for real time <i>in situ</i> observation of infiltration and crystallization processes in confined spaces via light microscopy (LM). This enables the investigation of new infiltration candidates under more realistic conditions without destroying original substrates. The MCTS was used to observe these processes for a commercially available nanolime and a newly prepared liquid calcium mineral precursor formulation based on complex coacervation.
