Abstract Glass-based pigments have an important role in the panorama of artistic production due to fact that their manufacturing processes involve a combination different skills and understanding, they disciplines ranging from glass technology metallurgy, glazed ceramic stone imitation vitreous mosaic tesserae painting materials. The main goal this manuscript is present critical review literatu...

STATEMENT OF PROBLEM Surface of porcelain restoration is a matter of clinical concern because of its abrasive action on the opposing enamel. PURPOSE This study comparatively evaluated wear of enamel when opposed by three different surface finishes of ceramic. MATERIALS AND METHODS A total of 60 metal-ceramic discs (10 mm × 2 mm) with different surface finishes were fabricated. They were div...

Methods: Forty disc-shaped specimens were fabricated with a feldspathic porcelain (Super Porcelain EX3), glazed, and randomly divided into 4 experimental groups and 1 control group (n=8/group). For the experimental groups, the glazed layer was ground with a diamond rotary instrument, and the surface was polished with: rubber points (Edenta), steel finishing burs (Meisinger), silicon rubber poin...

In this study, the overall performance of air PV/T, based on energy and exergy analysis has been investigated. Two combinations of air PV/T, which consist of unglazed and glazed air PV/T, are considered. Thermal analysis and numerical calculations were carried out, and the performance parameters of the system for the climate conditions of Kerman were studied. The results are presented in graphs...

The environmental concern, ensuring comfort for occupants, pushed us to search for the impact of glazed loggia on thermal comfort of adjacent space in Cons tantine climate, having s trong climatic cons traints. An experimental s tudy is undertaken and described in this paper. Analysis of the in situ results is also discussed. This work shows that in winter glazed loggia benefit largely from sol...

statement of problem: the effect of porcelain surface on the antagonist acrylic teeth has not been widely studied. objectives: this study aimed to investigate the effect of polished porcelain, glazed porcelain, and natural teeth (as the control group) on the acrylic resin teeth. materials and methods: in this experimental-laboratory study, a total of 60 specimens of glazed and polished porcelai...

The polymer solar cells were fabricated by a novel solution coating process, the roller painting. The roller painted film composed of poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) has smoother surface than the spin coated film. Since the roller painting is accompanied with shear and normal stresses and is also a s low drying process, the process induces eff...
