The methods based on the statistical pattern recognition are used for the evaluation of microscopic images of sol-gel matrices. The applied classification is a two steps scheme: dimensionality reduction of the data and cluster analysis. The obtained results have demonstrated that the molar ratio R (the number of solvent moles to the number of substrate moles) influences the stability of sol-gel materials, thus enabling us to reach the higher repeatability of the production process. It has been shown that the repeatability varies between 96.67% (for molar ratio R = 5) and 98.33% (for R = 15, 32, 50). This corresponds with the results of light scattering and transmission measurements.
