The ‘wind-rain’ house has a courtyard with glazed roof, which allows more direct sunlight to come into indoor spaces during the winter. The glazed roof can be partially opened or closed and automatically controlled to provide natural ventilation in order to adjust for indoor thermal conditions and the roof area can be shaded by reflective insulation materials during the summer. Two field studie...

Abstract Background and aim: Regarding the prevalence of monolithic zirconia and glazed ceramics IPS-e.max, and inadequate research on the color change of chlorhexidine and listerine mouthwashes on these two types,  this study was aimed to compare the effect of  these two mouthwashes on the stability of the The mentioned materials. Materials and Methods: This experimental study was carried o...

In this article, glaze with different colorants was applied to tile specimens manufactured by incinerated sewage sludge ash (ISSA) and clay. Improvements using different amounts of colorants, and glaze components and concentrations on tile bodies were investigated. Four different proportions of clay (by weight ratio) were replaced by ISSA. Tiles of size 12 cm x 6 cm x 1 cm were made and left in...

The purpose of the present study was to test the hypothesis that glazing will affect the Weibull modulus or the mean flexural strength of dental porcelain. Four groups (n = 30) of specimens were prepared from feldspathic body porcelain (Vita VMK 68). The specimens were tested in groups: original glazed condition (control), and after grinding separately with 1,000-grit, 600-grit, and 100-grit si...

The utilisation preference of glazed facades in the hot regions is accompanied by serious environmental and economic impacts. Attempts are continuing to fulfil an optimum balance between minimising heat gains and maximising daylighting benefits; in an economical approach. This study was conducted in Egypt, where a real case study was investigated to evaluate the thermo-visual performance of a b...

achaemenid glazed bricks of archaeological excavation of tall-e-ajori in persepolis city were studied by multiple instrumental analysis methods  such as xrf, xrd, sem-eds, icp and optical microscopy to identify the compositional features of glaze and brick body. glaze samples are apparently white and yellow  and this phenomenon are caused by the deterioration processes in burial environment, he...

In this paper, the use of local kaolin coming from Djebel Debbagh (denoted DD1) in composition ceramic glazes for sanitary ware was examined. Because its natural abundance, low price and good characteristics, represents an interesting economic alternative to other mineral clays. The chemical showed that contains 38.49 wt.% Al2O3 44.85 SiO2. Two based on DD1 denoted as GaDD1 GbDD1 were prepared ...

Graffiti can create detrimental aesthetic and environmental damage to city infrastructure cultural heritage requires improved removal methods. Incumbent laser, mechanical chemical techniques are often not effective, expensive or the substrate. Solvents generally hazardous always effective because of insolubility graffiti paint. This study proposes a simple strategy for safe removal, using bio-b...

Abstract The kinetics of expansion in ceramic materials due to rehydration and rehydroxylation was investigated since the early XX century as a cause crazing glazed ceramics. Since then, study mass gain has been studied extending monitored times modeling involved processes. In last 20 years, interest this process grew its possible application dating field, supporting well-established techniques...
