Journal of Raman Spectroscopy, 2014
The first archaeological evidence reported for tile production in Portugal was discovered in Santo António da Charneca (SAC), late 15th or early 16th centuries' pottery kiln, south riverside of Tagus River. Samples from this kiln were studied with the use of non‐invasive spectroscopies, namely, μ‐Raman, ground‐state diffuse reflectance absorption ...

Studies in Conservation, 2000
Abstract Traditionally, the glazed surfaces of antique tiles have been cleaned by a mechanical process, or by using chemical solvents applied directly to the surface. These chemical and abrasive processes may result in accelerated degradation of the tile, particularly the fragile ceramic body, or in scratches on the glazed surface.

Portugal is well known for its facades decorated entirely with ornamented glazed ceramic wall tiles called azulejos. On ageing, the tiles may detach and fall off, or deteriorate to such an extent that it becomes necessary to replicate them. Hence tile replication is a common practice in Portugal for facade restoration, but very often these new tiles do

Electrochemical Desalination of Historic Portuguese Tiles, Azulejos, in laboratory scale
2011Soluble salts causes decay of historic Portuguese tiles. Treatment options for removal of thesalts are few. The present paper deals with development of a method for electrokineticdesalination, where an electric DC field is applied. Experiments are conducted with XVIIIcentury tiles with and without mortar from the tile bed.

Metakaolin geopolymers applied in the conservation of tile facades: a Portuguese case study
2020<p>The possibility of using geopolymers to fill gaps/lacunae in glazed ceramic tiles (azulejos) has been studied. Since the 15<sup>th</sup> century, glazed ceramic tiles are characteristic elements of the Portuguese architectural heritage and their use as external rendering elements has made them prone

Painted tile panels (Azulejos) are one of the most representative Portuguese forms of art. Most of these panels are inspired on, and sometimes are literal copies of, famous paintings, or prints of those paintings. In order to study the Azulejos, art historians need to trace these roots.

A XANES study on the structural role of zinc in ancient tile glazes of Portuguese origin
X-Ray Spectrometry, 2008Abstract Lead‐rich blue‐and‐white tile glazes (16th to 17th century, Portuguese manufacture) were studied by x‐ray absorption near‐edge spectroscopy (XANES) to assess the speciation and coordination environment of zinc, a fuser metal commonly used along with lead in ancient glazes.

Environmental Science and Pollution Research, 2012
In the 1970s, a large ambulatory of the National Tile Museum, Lisbon, was closed with glass panes on both ground and first floor. Although this design was meant to protect the museum collection from ambient air pollutants, small openings between the glass panes remain, creating a semi-enclosed corridor.

Physical-chemical characterization of historical Portuguese tiles
2012A group of Portuguese tiles from the 17th century with manufacturing defects and several forms of decay were characterized as to chemical and mineralogical composition and physical properties of the glaze and ceramic body. The study included multi-analytical techniques: X-ray fluorescence (XRF), X-ray diffraction (XRD) and thermogravimetric and ...
