木叶天目釉初探

一、前言天目釉是我国古代著名的陶瓷色釉之一。它是我国劳动人民智慧的结晶。它起源于我国的宋代,以江西吉州窑和福建建安窑两地生产为主,传世珍品早已失传数百年。日本人对中国的天目釉颇感兴趣,它们通常将施有黑釉的陶瓷器称为天目。因为其配方特殊,烧制困难,所以在世界陶瓷史上素享盛名。木叶天目是用天然树叶按照一定的艺术规律布于施有墨色或茶褐色天日底釉的陶瓷坯体上,经高温焙烧,树叶灰与底釉相融合而形成黄色的木叶纹样。其在深色底釉的映     

鲁花釉的陶瓷绘画特点

<正>山东淄博有着得天独厚的良好的陶土资山源,经陶瓷技师们的不断实践摸索,并依托宋代雨点釉、茶叶末釉,在上世纪七十年代末,鲁花釉陶瓷装饰绘画在此基础上应运而生。鲁花釉底釉为乌金釉。乌金釉是在本地白碳土中获萃取,烧制成色好的乌金釉釉面,象晴朗夜空中金星闪烁,莹润亮泽。这就是鲁花釉—山东的陶瓷窑变釉。中国的窑变釉有很多种,是在历代艺匠们劳作与生活的需求以及工艺材料运用时的偶然巧遇发现的。鲁花釉以乌金底釉为基础,在乌金釉上面施加所需的颜色釉,在烧制过程

Zircon-free frits suitable for single fast-firing opaque wall tile glazes and their industrial productions

Wall tile glazes with a smooth surface texture, high glossiness, and whiteness are usually based on zirconium containing frits. However, these frits are quite expensive and therefore, there have recently been certain attempts to lower the production cost such as taking suitable glass–ceramic glaze systems into an account. With the present work, the frit-based glaze compositions belonging to the K₂O–MgO–CaO–ZnO–Al₂O₃–B₂O₃–SiO₂ glass–ceramic system were studied to prepare newly synthesized wall tile glazes for industrial single fast-firing. The design of a glass–ceramic glaze for this type of tiles should ensure that the selected frit precursor is technically and commercially compatible with the manufacturing conditions generally used in the production of glazed ceramic wall tiles. The aim of the study is to develop zircon-free, frit-based, glossy opaque glass–ceramic glazes for wall tiles by optimizing the CaO/MgO and adjusting the Al₂O₃/alkali ratios in the starting frit compositions. Frit production, glaze preparation, application, and single fast-firing of wall tiles were, first of all, conducted under laboratory working conditions and then, successful recipes were adapted to the relevant industry. The frit crystallization capability and crystallization temperature range were determined by differential thermal analysis (DTA). Thermal expansion coefficient values of glazes were determined by a dilatometer. Characterization of single fast-fired glass–ceramic glazes was made by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) techniques. Colour and gloss analyses of the final glazes were measured with a spectrophotometer and a gloss meter, respectively.     

Melting behaviour of raw glazes

Melting behaviour of raw and inhomogeneous glazes influences the appearance and the properties of the final glaze surface. The melting behaviour was estimated from the sintering curves and characteristic samples measured with hot-stage microscopy. The glaze compositions were statistically chosen to cover the glaze-forming systems used in traditional ceramic industries. Altogether seventy-five compositions were mixed and ball-milled from seven different raw materials. The temperatures describing the sintering and melting of the glazes were mathematically modelled as functions of the raw material compositions. All the compositions were then also applied on raw floor tiles and fired in an industrial kiln for fast-firing (50 min) of dense floor tiles. The gloss of the fired glazes was mathematically modelled as a function of both the raw material and the oxide compositions. The resistance to abrasion and the crystalline phases of the fired surfaces were also determined.

Microstructure and cleanability of uncoated and fluoropolymer,zirconia and titania coated ceramic glazed surfaces

The aim of this investigation was to examine the effect of surface topography of different compositions and surface coatings of glazed ceramic tiles on their cleanability. The cleanability was estimated with color measurements. Contact angle measurements were used to describe the surface properties and profilometry and electron microscopy to describe the topography. The effect of additional coatings on the surface properties was compared by applying experimental zirconia and titania coatings as well as a commercial fluoropolymer coating on one of the experimental and all reference glazes. The results show that there were clear differences between the soiling tendencies of the glazes. Generally the topography measurements show that the rougher was ceramic glaze, the more soil adhered on its surface.     

Study of a quantitative method to evaluate the wear resistance of glazed tiles

As glazes are papery, there is no method capable of evaluating the surface wear resistance of glazed tiles. Thus, Taber abraser with rubber wheels and abrasive belts was employed to grind out a regular wear track. The volume of track was estimated using profilometer and its analyzing software precisely. The evaluation reliability of this method was verified using six float glasses, and the standard deviation of volume loss results could be controlled less than 10%. The appropriate operating parameters were investigated using float glasses and two types of ceramic tiles from different manufacturers. The method proposed in this work has potential of success to evaluate the surface wear resistance of ceramic tiles quantitatively and precisely.     

Stability of (Cr)CaO.SnO2.SiO2 pink pigment in ceramic frits

Abstract

Incorporation of the (Cr) CaO.SnO₂.SiO₂ pigment in ceramic glazes yields colours with a red component the hue of which depends on the nature of the frits used to produce the glazes. Several samples were prepared by adding this pigment to different frits commonly used in the manufacture of glazed ceramic tiles, each sample subsequently being fired at the appropriate maturing temperature. A study of the resulting glazes shows that variations in colour arise as a result of the three possible phenomena which may develop in firing depending on the frit composition used. These three phenomena are pigment dissolution in the glassy phase, devitrification of crystalline phases whose nature differs from that of the pigment, and immiscible glassy phase separation.     

Recycling in ceramic glazes of zirconia overspray from thermal barrier coatings manufacturing

Glazed ceramic tiles are the most common building material for floor and wall covering. Glazes are produced from frits. The aim of this work is to make a total or partial replacement of a raw material, zircon, widely used in ceramic tiles manufacturing, with a waste material, in order to prepare ceramic frits. The waste material used in this work, is the overspray zirconia, which is produced during the deposition process by atmospheric plasma spraying (APS) of thermal barrier coatings (TBC) on turbine blades. In particular, a replacement of 100 wt%, 1 wt% and 0.2 wt% of zirconium silicate with zirconia has been studied. Ceramic glazes prepared mixing frits and other raw materials are applied on a single-fired tile. The glazes obtained were characterized with different analytical techniques. This study has revealed that the substitution of zircon with waste zirconia is possible in small percentages due to the presence of small amount of chromophore ions in the overspray zirconia, which tend to colour the glaze.     

Recycling of yttria‐stabilized zirconia waste powders in glazes suitable for ceramic tiles

The aim of this work is to demonstrate the feasibility of valorizing and recycling Yttria‐stabilized Zirconia thermal spray waste into high value products for industrial and residential use. Based on the powders chemistry and morphology, this work aims to realize products, like frits suitable for white glazes and ceramic tiles. The focus is on one class of powder: high‐temperature and abrasion‐resistant ceramics, like Yttria‐stabilized zirconia. This study has revealed that the substitution of pure zirconia with waste Yttria‐stabilized zirconia is possible in high percentages, up to 100% to prepare frits suitable for white glazes.     

Technological evolution of ceramic glazes in the renaissance: In situ analysis of tiles in the Alcazar (Seville,Spain)

The Alcazar Palace (Seville, Spain) is famous for its ceramic decorations; 16th century wall tiles of different typologies have been analyzed in order to relate the manufacturing process of their colored glazes to the evolving technologies of the Renaissance. Chemical and mineralogical compositions have been determined in situ by nondestructive X-ray fluorescence and X-ray diffraction on arista ceramics in the Cenador de Carlos Quinto, and majolica ceramics in the Palacio Gotico and the Royal oratory. The arista style belongs to the local Hispano-Moresque ceramic tradition. Majolica tiles have the complex microstructures of glazes from Italy. The two types are clearly differentiated by their typology, morphology (curved vs flat surface), and also microstructure (single vs multi-layers), glaze chemistry, and use of different coloring agents. Moreover, we found different glaze chemistries in the investigated majolicas, which correspond to different artists and/or practices.
