Optical micrographs of: Carrara Marble treated with NANOMATCH1 product (plane-polarized light) (a) and CaLoSiL® (crossed-polarized light) (b); Laspra dolostone treated with NANOMATCH1 product (crossed-polarized light) (c) and CaLoSiL® (crossed-polarized light) (d); Savonnières limestone treated with NANOMATCH1 product (crossed-polarized light) (e) and CaLoSiL® (crossed-polarized light) (f). Red arrows indicate the surface microcrystalline layer formed after the consolidating treatment executed with the two products.
