Surface smoothness of ceramic glazes is always an important characteristic of ceramic glazes as a point of surface engineering studies. Surface roughness affects chemical resistivity, glossiness and stainabiliy of glazes. In fact, less surface roughness improves cleanability of the surface by the least usage amount of detergents. In this investigation, surface topography of two common opaque gl...

The effect of iron oxide content on the crystallisation of a diopside glass–ceramic glaze was investigated using a glass–ceramic frit in the K2O–ZnO–MgO–CaO–Al2O3–SiO2 system and a granite waste glass. Measurements by X-ray diffraction (XRD) combined with scanning electron microscopy (SEM) and EDX microanalysis showed that the distribution of Fe ions among different crystalline phases such as f...

The processing power of mobile devices is increasing steadily; their screen size suffers more fundamental limits. Given this contrast, we identify mobile information visualization which maximizes the effectiveness of small screen displays as a key area for future development. To achieve this, we present an overview of Glaze, a plug-in based visualization framework for mobile devices based on th...

PURPOSE This study aimed to evaluate the effect of surface treatments on bond strength of indirect composite material (Tescera Indirect Composite System) to monolithic zirconia (inCoris TZI). MATERIALS AND METHODS Partially stabilized monolithic zirconia blocks were cut into with 2.0 mm thickness. Sintered zirconia specimens were divided into different surface treatment groups: no treatment (...

abstract today, pottery in shahreza of isfahan is a valuable arts with its up and downs which has stabilized  its place among iranian pottery centers. the investigation of contemporary pottery in the course of  history shows that iranian potters have used predecessors' experiences, as well as remained  professions of pottery art such as soheili, bahari and fakhar, and tried to promote qual...

This study evaluated the influence of an alternative surface treatment on the microshear bond strength (μsbs) of zirconia-based ceramic. Thirty-five zirconia disks were assigned to five groups according to the following treatments: Control (CO), glass and silane were not applied to the zirconia surface; G1, air blasted with 100μm glass beads + glaze + silane; G2, a gel containing 15% (by weight...

The study of terrestrial geomicrobiology and its relationship to rock weathering processes is an essential tool in developing analogues for similar processes that may have occurred on Mars. Most studies of manganese-enhanced rock varnish have focused on samples taken from warm arid desert regions. Here, we examine samples obtained from eolian-abraded lava flows of the 4700-4800 m high Ashikule ...

The aim of this study was to assess whether surface treatment improves zirconia-porcelain adhesion. The 3Y-TZP blocks were cut into squares, then polished and sintered. The zirconia surface treatments were performed as follows: no treatment (C); tribochemical silica coating (TBS); glaze application + hydrofluoric acid etching (GA); glaze application + hydrofluoric acid etching + silanization (G...

In this work was investigated the feasibility to use Waste Electrical and Electronic Equipment (WEEE) glasses in construction sector as secondary raw material. WEEE glasses were used in different percentages as a function of the product obtained: 30-40wt% for glaze formulations, about 40wt% for glass-ceramics and 5wt% in brick bodies. The laboratory and industrial scale up results demonstrated ...
