异彩釉是我所新试制的一种色釉。它是在结晶釉和花釉的基础上发展起来的新型色釉品种。分别采用硅酸盐釉与各种乳浊性色釉及黑釉土结合硅酸锌使用,在色釉底釉上加施硅酸锌,用黑釉土做底釉或部分底釉均施色釉加硅酸锌,形成三类不同装饰效果的釉色系列。异彩釉装饰效果丰富多采而方法 相似文献

龙泉务窑黑瓷粗、细胎用原料分别与白瓷粗、细胎相同,故可以认为当时该窑在制作瓷坯时是不分黑瓷白瓷的,只是涂釉不同。样品外观分为茶叶末釉、酱色釉、油滴黑釉和普通黑色釉,它们釉的含铁量在3 .3 - 7 .8 % 。釉滴黑釉组成特征是含高硅(74 .1 % ) 、低铝(12 .1 % ) 和低铁(3 .3 % ) ,其釉属钙碱釉,釉较厚,釉表面有磁铁矿微晶,使外观呈银色小油滴。茶叶末釉属钙质釉,釉中生长较多的钙长石和普通辉石晶体,还有残留石英和磁铁矿结晶,所以形成茶叶末釉的外观。酱色釉是由部分含铁量较高(6 .6 - 7 .8 % ) ,钙镁氧化物含量较低的黑釉在较高的烧成温度和较强的氧化气氛下烧成,釉面生成赤铁矿晶体层,故外观表面呈酱红色,面下仍为黑色。样品烧成温度1200 - 1300 ℃。 相似文献

用稀土化合物研制无钴黑色颜料和釉料 总被引:1,自引:0,他引:1
一、概况陶瓷工业用的黑色颜料和黑釉是一种名贵的色釉。早在东汉时期,在浙江上虞即能用还原气氛烧出较深的黑釉。东晋时德清窑烧出了纯正的黑釉。这些黑釉主要是用含铁粘土于还原气氛烧成,但呈色很不稳定。烧成工艺难于掌握。近代陶瓷工业多采用Fe_2O_3—Cr_2O_3—Co_2O_3—Mn_2O_3金属氧化物先制成色剂或直接加入到基础釉中(?)制得黑釉。虽不受气氛限制,但必须在不含锌的石灰釉中,且价格昂贵,釉料成本高而不利于大批量生产。目前一些地区利用当地含 相似文献

Black glaze and brown glaze porcelains were an important part of ancient Chinese iron-based high temperature glazes. The excavation of black glaze and brown glaze porcelains from the Yuan and Ming dynasties at the Qingliang Temple kiln site in Baofeng, Henan, China, in 2014, enriched the firing history of this kiln site and history of Chinese ceramics. In this study, black glaze and brown glaze porcelain samples from the Qingliang Temple kiln site from the Yuan and Ming dynasties were selected and analysed via optical microscopy, laser Raman spectroscopy, focused ion beam scanning electron microscopy combined with EDS and energy dispersive X-ray fluorescence to determine their microscopic morphology, microzone composition, microstructure and chemical composition. Moreover, the main wavelength range of the brown glaze porcelain samples were measured by UV–Vis–NIR spectrophotometer systems. The main conclusions of this study are as follows. The brown glaze porcelain from the Yuan and Ming dynasties at the Qingliang Temple kiln site has two different colour layers, with the surface is brown and the bottom is black. The presence of a glass phase and α-Fe2O3 phase in the black glaze porcelain samples, and a rare ε-Fe2O3 phase in the brown glaze porcelain samples. The brown colour was a result of ε-Fe2O3 precipitation, whilst the black base layer also enhanced the brown-colouring effect. Different glaze formulations were used for brown glazed porcelain, some of which were similar to those used for black glaze porcelain and derived from the transformation of black glaze porcelain through different firing atmospheres and cooling rates. Although the formula of the brown glaze porcelain samples exhibited differences, the main wavelength difference was not large, was within the 645–682 nm range and belonged to the visible red region. 相似文献

缩点釉是一种釉面会收缩成点粒现象的釉。阐述了缩点釉产生的机理.介绍了研制经过,讨论了几个影响缩点效果的问题。并指出只要合理地选用原料.调整好坯釉配方,掌握好施釉厚度和烧成温度。是可以得到均匀、好看、美观的“缩点釉”的;若能在装饰对象和装饰方法上大傲文章,可以使这一具有“缺陷功能”的釉种产生更好的艺术效果。 相似文献

为降低制备成本,有效利用工业废弃物,以赤泥作为氧化铁主要来源,在1120℃左右烧成,制备出了较为理想的低温红油滴釉。探讨了釉组成中ZnO、B2 O3、CaO、MgO、Fe2 O3、Al2 O3等氧化物含量对釉面光泽度、油滴形成的影响。研究发现,低温油滴釉的形成主要基于釉的分相;B2 O3、ZnO的引入不仅可促使釉分相,并能降低釉的熔融温度增加基础相的透明度,从而得到光泽度良好的低温油滴釉;调整CaO、Al2 O3等的含量可以控制分相的产生及分相的结构;Fe2 O3会富集在油滴状的微相中;ZnO、MgO对油滴釉的颜色有较大影响,增加ZnO的含量则油滴釉由黑色变为棕红色,增加MgO的含量则油滴釉由棕色变为黑色。研究了釉层厚度对油滴形成的影响,釉层厚度为1~1.5 mm时形成的油滴效果最好。 相似文献

AbstractIn the ceramic tile industry opaque glazes with considerable zircon content are widely used. However, the high cost of zircon limits its wide use in relevant glaze compositions. In the present study, a model opaque glaze was modified by changing the alumina/silica ratio, adding potassium oxide, or using a higher content of opaque frit while gradually eliminating the zircon content in the glaze batch. After glaze preparation, application, and single firing of glazed floor tiles under industrial conditions glazes were characterised by XRD, SEM, and EDX. The optimum alumina/silica ratio was found to be 0·26. Colour parameters L, a, and b of starting and final glazes showed that an increase in opaque frit content gives more positive improvement in opacity and in dry abrasion resistance than potassium oxide addition. Removal of zircon from the glazes resulted in a decrease of ~13–18% in glaze cost without detrimental effect on opacity. 相似文献
