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

open access: yesJournal 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 ...

PROVENANCE STUDIES IN ARCHAEOLOGY – MORE REFLECTIVE OF ‘QUALITY CONTROL’ WITHIN A RESOURCESCAPE THAN GEOCHEMISTRY?

open access: yesOxford Journal of Archaeology, Volume 43, Issue 1, Page 97-105, February 2024.
Summary Despite the obvious methodological similarities between archaeology and geology, we argue here that the fundamental assumption in scientific provenance studies of inorganic artefacts provides an insufficient basis for the methodology. That assumption is that there is a geochemical link between the source of the raw material and the finished ...

ARCHAEOLOGICAL EVIDENCE FROM GUA LADORI, NORTH KONAWE, SOUTHEAST SULAWESI

open access: yesParadigma: Jurnal Kajian Budaya
The presence of archaeological sites, mostly caves, in North Konawe Regency provides evidence of human habitation dating back to prehistoric times. Despite the challenges posed by difficult terrain and limited access, which hinder archaeological research,

Special enamels for porcelained stoneware substrates

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2000
In the present work, a ceramic glaze compatible with the porcelained stoneware body and presenting a good glaze-body adaptability, has been obtained. Taking into account its industrial applicability, we have started from industrial raw materials, formulating compositions of transparent and opaque frits so as to, once applied on porcelained stoneware ...

Glass bottles powder’s impact on the technological characteristics of clay mixtures used for porcelain stoneware tiles [PDF]

open access: yesCerâmica
This study aims to enhance porcelain’s physicochemical properties by adding glass powder as flux. Kaolinitic clay, sand, and glass powder were used to formulate six grades, fired between 1140-1260ºC for 2 h. Specimens were tested for shrinkage, mass loss,

Viscous flow sintering of porcelain stoneware revisited.

open access: yes, 2018
Porcelain stoneware tiles, as porcelain items, are sintered by vitrification through viscous flow of an abundant liquid phase formed at high temperature. Such a process must be kept under strict control to achieve the desired properties of final products and prevent defects induced by pyroplasticity.
