Generally, the deformations of ceramic materials during and after firing may have a complex origin. If the products are made up of a single material, such deformations are mainly due to pyroplastic phenomena. In the case of multi-layer materials …
Heating microscopes were commercially introduced 60 years ago, and they immediately gained an important role in material science and engineering thanks to their wide field of application [1]. Nowadays, these instruments are used in both industry and …
A new optical technique has been introduced to measure the state of tensions in glazed ceramic bodies, it has already been applied to the study of delayed crazing and pyroplastic deformation of ceramic body. The report explains how ceramic …

Generally, the deformations of ceramic materials after firing may have a complex origin. If the products are made up of a single material, such deformations are mainly due to pyroplastic phenomena. In the case of glazed materials, two further factors …
The glasses are intrinsically complex systems, quite difficult to study because their structure has no long range order and they are not in a thermodynamically stable state. Ceramic glazes are undoubtedly far more complex than glasses because in most …
The manufacturing of porous wall tiles is quite ancient but even with the newest technology still suffers of old problems. The study of the state of tension between glaze and body is fundamental in order to avoid some common defects, such as delayed …

This report has been presented at the meeting called "Actualisation and improvement of raw materials and ceramic bodies quality for tiles production", which was held by Faenza Editrice, Sassuolo, Auditorium Assopiastrelle, 16 february 2006. Some …
Some frequent glazing defects such as crazing are caused by an inadequate state of tension between the glaze and the ceramic body which is strongly related to various parameters. The most important are the coefficients of thermal expansion of glaze …
