Abstract: The goal of this paper is to review the latest innovations in ceramic tile decorating techniques, encompassing not only the most widespread techniques, such as inkjet printing, but also other decoration techniques with a strong potential to provide tile surfaces with new finishes and enhanced aesthetics, such as physical vapour deposition and laser treatment.

Abstract: During the cooling of ceramic materials stresses arise that cause flows of material. These flows lead to residual stresses in the materials at the kiln exit. Laboratory tests were carried out using a composition based on white-firing clays, which was fired according to cycles with different cooling rates. Residual stresses were measured using the layer removal method. The internal temperature profile during industrial cooling and the stress generation process were simulated. The results of the simulation fit with great accuracy the experimentally measured residual stress values.
