Zarinfam is a specific glaze with metallic reflection. Its color and optical properties are due to two optical phenomena of light interference and Surface Plasmon Resonance (SPR) related to noble metal nanoparticles in the Zarinfam layer. In this communication, the optical properties of lustre glaze produced on the copper shield were studied. For this, first, the reflectance spectra of samples were measured in the visible domain. Then, a model was developed, thanks to FESEM images. Using this model, different sample parameters, spatially the glass thickness and silver volume fraction in the samples were evaluated. The results showed that the glass thickness varies from ۳۰ to 90 nanometer and the silver volume fraction is in 0.01 per cent of order.
