An overview of Principal Components Analysis approaches in Raman studies of cultural heritage materials

Journal of Raman Spectroscopy, Volume 55, Issue 2, Page 125-147, February 2024.
The present overview answers the need of evaluating the current state of the art concerning the application of principal components analysis (PCA) to Raman spectroscopy studies of cultural heritage materials. Painting materials, both colouring and binding ones, were considered, together with natural and synthetic glasses, biogenic and mineral ...

Effects of Glass Waste Addition on Technological Properties of Porcelain Stoneware Tiles

Key Engineering Materials, 2001
The aim of this research is to assess the effects of the addition of waste glass on both technological behaviour and technical properties of porcelain stoneware bodies. Several bodies were designed adding up to 10% waste (float and container glass) to a typical industrial formulation in replacement of sodium feldspar.
