A sample produced to replicate earthen finishes found at Mesa Verde National Park with a thicker plaster layer covered by very thin wash layer. These samples are made using pure kaolinite or montmorillonite clays and ground silica in proportions similar to those of the earthen finishes found on site. The facsimile samples will be treated with various ethyl silicates and subjected to tests to assess the performance of the consolidants. Photo: Amila Ferron, GCI
