“…Das et al [4] characterized and evaluated the influence of five different clays of Indian sources on wall tile compositions. The results showed that the compositions containing a higher amount of quartzitic clays possessed lower shrinkage (<1.0%) in the temperature range of 1050-1150°.…”

Due to the fact that there are various types of wall tiles in the Egyptian market, of different qualities and prices, the aim of this research paper is to evaluate the properties and characteristics of tiles obtained from the local Egyptian market and attempt to identify the reasons for such differences. In other words, investigate the reasons why some tiles are more superior in quality than others. Test specimens were obtained from the local Egyptian market for fourteen factories. The mechanical properties (namely flexural strength) and physical properties (namely water absorption and apparent porosity) were measured, as they reflect the strength, the endurance during handling, as well as, the conditions to which the tiles are expected to be exposed to during use. The impact resistance and hardness were tested as well. Also, the phases (both major and minor) developed during the firing (maturing) step of manufacturing were identified. A correlation was made between the measured properties and the formed phases. The results showed that samples which yielded high physical and mechanical properties are those that constituted mainly the major phases, specifically, mullite and quartz, while those that contained impurities in the raw materials inevitably resulted in the development of minor phases, in addition to the major phases, had a negative effect on the measured properties. Consequently, it is feasible to obtain tiles that satisfy the requirements of ISO 13006 specification provided that the used raw materials are free (as much as possible) from impurities such as hematite, magnesium, and calcium.

“…The XRD result clearly excludes the use of chalk (CaCO 3 ), a traditional and widely reported coating pigment in ancient Chinese architectural painting, in the ground coat layer [11]. Rather, it agrees well with crystalline phases noticed in fired clays, therefore suggesting a possible use of powder of fired clays as coating pigment [11,12]. The practice of using brick powder as a coating pigment has been very often witnessed in architectural painting and decoration (especially on modern pseudo-classical architecture) [13].…”

Hexi painting (和玺彩画) was historically documented as the most sophisticated decorative art representing the highest levels of technological knowledge and skills for decorating the Chinese Qing (1644-1911 AD) imperial architecture. However, the technological complexity of Hexi painting has barely been scientifically investigated. This article presents a technical case study that aimed to promote a better understanding of (inorganic) materials used in, and the painting/decorating procedure of, Hexi painting. Microscopic examination, compositional analysis, and phase/fiber identification were applied on fragments of golden-dragon Hexi painting (金龙和玺彩画), the most prestigious form of Hexi painting, which were sampled from Xitian Fanjing (西天梵境) in Beihai Park (Beijing, China). The results suggest that neither the kinds of used (inorganic) materials nor the painting/decorating process is exclusively restricted to Hexi painting and distinguishes it from other contemporaneous decorative forms. It is the combination of material use and the painting/decorating procedure that seems to make Hexi painting special. Further studies are needed to investigate the use of organic materials in Hexi painting to expand our current understanding.

“…This property, as most properties of a hygroscopic material, varies with the moisture content in the product. Also, controlling shrinkage is an important criterion, especially in the case of manufactured building products (bricks, faience, and tiles), because excessive shrinkage causes the deformation of the items during firing [1]. Density and shrinkage were investigated in many papers.…”

This paper is a contribution to the determination of the variations of the physical and rheological properties of a ceramic paste during drying. The ceramic's density was determined as a function of moisture content using the Archimedes' Principle. The shrinkage was derived from the experimental density data and also determined by measuring the variation of the sample's dimensions during drying. Compression tests were performed at different deformation rates in order to identify the linear and non-linear viscoelastic domains of the material. Relaxation tests were carried out and the results of fitting showed that the generalized Maxwell model could be used to describe the viscoelastic behavior of the samples. Rupture tests were also made to measure the strength of the material for different moisture contents and to study the influence of temperature on the strength of the dried product.
