论宋代景德镇青白瓷的历史分期及其特征

中国是瓷之母国,青白瓷是瓷之母国的一朵奇葩,青白瓷是宋代六大瓷系之一,以景德镇窑为代表,其釉色介于青白之间,青中闪白,白中显青,故名。宋代是青白瓷的辉煌时期。考古发掘资料表明,目前已在国内十多个省,近150个县和国外20多个国家或地区出土了宋代青白瓷。景德镇从宋代生产青白瓷以后便声名鹤起,为天下所注目。宋真宗将青白瓷定为贡品,并以其“景德”年号（公元1004-～1007年）命名此地,使天下皆知有“景德镇”。因此可以说,青白瓷是景德镇成为世界瓷都的起点,在中国乃至世界制瓷史上具有重要意义。     

宋代青白瓷系及其烧造探讨

宋代景德镇是青白瓷的代表,生产青白瓷的景德镇窑已被大家所熟知。但在其它地区还有诸如吉州窑、龙泉窑、德化窑等也生产青白瓷。本文选取宋代这些青白瓷窑为研究对象,通过相应的出土实物详细阐述了各窑的青白瓷的烧造特点,并与景德镇青白瓷对应比较。     

宋代景德镇青白瓷"尚玉"审美意蕴研究

青白瓷的兴起缘于玉器的减少,“尚玉”是宋代景德镇青白瓷追求的审美境界,青白瓷“尚玉”意蕴与“崇青”的色彩崇尚都缘于“如玉”之美四个方面。论述了宋代景德镇青白瓷“尚玉”的审美意蕴。     

景德镇瓷业生产体系形成时代考

景德镇是闻名世界的瓷都,自明代以来便成为中国的制瓷中心,明代宋应星《天工开物·陶埏》对景德镇制瓷工序的详尽描述,为世人呈现了完善的景德镇瓷业生产体系。其实,景德镇瓷业生产体系的形成与完善经历了一个较长的历史时期,而并不是到明代成为全国制瓷中心时一蹴而就的。后人对景德镇瓷业生产体系的引用,绝大多数征引《天工开物·陶埏》,尤其是文尾"共计一坯工力,过手七十二方克成器,其中微细节目尚不能尽也"的描述,认为景德镇瓷业生产体系在明代才得以形成。通过对文献研究、结合考古调查工作及对宋代景德镇窑产品的分析,提出景德镇瓷业生产体系至迟在南宋时期就已经形成了。     

淡极始知花更艳——刘钦莹

正在瓷都景德镇的"景漂"当中,有一位漂龄近二十年的中国台湾陶瓷艺术家,他就是景德镇当代汝瓷的拓荒者和集大成者刘钦莹。刘钦莹1953年出生于中国台湾省高雄市,自号"石桥茶人",别号"瓷疯"。刘钦莹得名"瓷疯",源于他心无旁骛,如痴如疯的制瓷态度;源于他能够独自完成制瓷全过程的过人能力;还源于他仅用半年时间就复活宋代天目釉的传奇经历。

历久弥坚

正景德镇制瓷业始于东汉,1700多年窑火不熄。从唐朝武德年间镇敏陶玉"载瓷入关中,称为假玉器",到北宋景德元年(公元1004年),宋真宗命进御瓷,因瓷底书"景德年制"而"天下咸称景德镇瓷器",景德镇由此得名至今,成为中外陶瓷之圣地。岁月如歌,沧桑巨变,景德镇作为世界上的瓷都,经受住了久远的考验,始终挺立。悠悠昌江水不尽,瓷都窑火燃千年。景德镇兴于瓷,历史进

氢气纯度分析方法准确性的探讨

ONACCURACYOFANALYSISOFOFHYDROGEN1前言我公司目前应用的氢气纯度分析方法有两种,一种是爆炸反应法,另一种是焦性没食子酸吸收法。几年来,人们对两种分析方法的准确性曾有过褒贬不一的评论。这里我们也谈谈自己粗浅的观点。2爆炸法测定氢气纯度一定量的氢气样品与适量的空气之均匀混合物因反应后生成液体水而引起气体体积减少,减少的体积等于参加反应气体体积之和。其中l／3为氧气,2／3为氢气。根据氢气取样量和反应前后混气体体积之差,以及氢气在反应中的体积比例关系,可计算出样品的氢气纯度。计算公式式中：A一混…     

COMPARISON OF METHODS OF ANALYSIS OF GYPSUM1

The different analytical methods proposed for the evaluation of gypsum have been subjected to an experimental test. A combination method, consisting of a fusion with KHCO₃ and determination of CaO by KMnO₄ titration, the SO₃ by Andrews method of titration of BaCrO₄ has been found to give very reliable results with the least consumption of time.     

SEDIMENTATION OF BINARY MIXTURES OF PARTICLES OF UNEQUAL DENSITIES AND OF DIFFERENT SIZES

A model is developed for the sedimentation from a suspension of two particle species of unequal densities and of different sizes. The composition and the thickness of various layers in the sediments are predicted using graphical and analytical methods. The model predictions were in excellent agreement with experimental results, when the particle size ratio was ≥ 108. When size ratio of the particles was 2.60 and 4.31 the agreement occurred in about 50 percent of the cases.     

HEASUREHENT OF INSTANTANEOUS RATES OF LOSS OF VOIATILE COMPOUNDS DURING DRYING OF DROPS

A novel technique serves to monitor instantaneous rates of loss of a volatile solute from a suspended drop during drying. A highly sensitive electron capture detector is used to monitor concentrations of SF6 released into a flowing gas stream from a suspended, drying drop. Simultaneously, the appearance and morphological development of the drop are monitored with a video camera. This provides the wherewithal of relating instantaneous rates of loss of the volatile solute to particular events during the development of particle morphology.

Initial experiments have been carried out with drops of aqueous solutions of glucose, sucrose, maltodextrin and coffee extract. The results clearly display the onset of the volatiles-retentive selective diffusion phenomenon. There is also substantial loss of the volatile component later in the drying process, when the drops undergo repeated ex ansion, bursting and cratering due to the formation of internaf bubbles. These experiments appear to be the first quantitative demonstration of major losses accompanying changes in drop morphology.

ANALYSIS OF RECENT MEASUREMENTS OF THE VISCOSITY OF GLASSES

Viscosity of Simple Soda-Silicate 500° to 1400°C Comparison of the results given by English with those of Washburn, Shelton and Libman, indicates a discrepancy in the absolute values of log₁₀ viscosity amounting to 0.6, those of Washburn et al., being relatively too high. If correction for this is made, the isothermal curves of log₁₀ viscosity as a function of soda content are smooth up to 50% Na₂O, showing no inflection. The observations as a function of temperature T are all represented within accidental error by an equation of the type where all three constants vary regularly with the composition. Change of Viscosity of Glass (6SiO₂, 2Na₂O) due to Molecular Substitution of CaO, MgO and Al₂O₃ for Na₂O The effect is clearly brought out by plotting (from the results of English) the change of log₁₀η due to the substitution as a function of temperature. The curves each show a sharp bend at a temperature between 840° and 1050°C, which is designated the aggregation temperature T_a. If we divide these curves by the corresponding percentage substituted, we get curves for each oxide which are straight and parallel below the aggregation temperatures, the slopes (increase of change of log₁₀η per 100°C) being −0.056 (CaO), −0.055 (MgO), −0.018 (A1₂O₃) per per cent oxide substituted. For substitution of 1/2 molecule the slopes are −0.325 (CaO), −0.23 (MgO) and −0.18 (Al₂O₃) per 100°. At the aggregation temperature the change of log₁₀η per per cent is a minimum, 0.03 to 0.06 for CaO, 0.12 for MgO, 0.07 for Al₂O₃. Evidence of Aggregation in Glasses, from viscosity Measurements The sharp bends in the plots of change of log₁₀η due to substitution of an oxide for Na₂O, suggest the beginning of molecular aggregation at these temperatures. These aggregation temperatures are close to the devitrification temperatures, but the effect on the viscosity curves cannot be due to actual devitrification since it does not change with time. Taking the aggregation temperatures as equal to devitrification temperatures, additional isotherms are roughly sketched into the equilibrium triangle of the system Na₂O-CaO-SiO₂. Change of Viscosity of Glass (4SiO₂, 2Na₂O) due to of Substitution of B₂O₃ for SiO₂ The change of log₁₀η (from the results of English) is plotted as a function of temperature, and also the change of log₁₀η per per cent B₂O₃. The curves are more complex than for the substitution for Na₂O.
