越窑是我国南方著名青瓷窑口。为了揭示后司岙越窑窑址匣钵的制作工艺,本文从科学技术的角度利用EDXRF、热膨胀仪等现代测试分析手段,对越窑出土的匣钵标本进行了胎元素组成、烧成温度的测试,并对实验数据进行多元统计分析,初步探讨了后司岙越窑窑址匣钵的制备工艺。研究表明:瓷质匣钵的化学组成与白洋湖泥土和后司岙窑址附近采集的泥土成分接近,这表明后司岙唐五代匣钵的主要原料可能来源于其窑址附近的沉积粘土,但在粗质匣钵中可见明显的粗颗粒。为了进一步探明这些粗颗粒的来源和特点,对其进一步分析发现,粗质匣钵中的粗颗粒主要是一些石英颗粒,为人工刻意掺入以提高匣钵的使用性能,粗质匣钵中粗颗粒的掺入也体现了粗质匣钵和瓷质匣钵在制作工艺上的差异。 相似文献

刘家门钧窑瓷器胎釉成分的EDXRF分析 总被引:2,自引:1,他引:1
采用能量色散X射线荧光法,分析了河南省禹州市刘家门窑址出土钧瓷、青瓷的胎、釉成分,探讨了钧瓷与青瓷在胎、釉原料配方上的差异。分析表明,刘家门窑址出土的钧瓷和青瓷,它们的瓷胎具有相同的原料配方。与青瓷相比,钧瓷瓷釉的Al2O3含量较低,SiO2含量较高,但二者的助熔剂含量相近。钧瓷瓷釉的成分落在K2O-Na2O-CaO-MgO-Al2O3-SiO2系釉的分相区域,因而产生了异于普通青瓷的蓝色乳光效果。分析还发现,不同时期的钧窑瓷器,其主、次量元素含量变化甚微,这暗示在长期的烧制过程中,刘家门窑瓷器胎、釉的原料配方较为稳定。 相似文献

本文以上虞地区三处窑址出土的青瓷粉盒为分析对象,首先依据其出土地层及类型学特征,将其年代定于北宋中期,其次对其进行统计分析发现其所占比例较高,而窑址中出土粉盒的成品率却很低,由此认为由于收益可观,当地民窑仍大量生产,从而得出当时女性对越窑青瓷粉盒的需求旺盛这一结论,同时结合墓葬出土实物及历史学研究成果认为当时的具体消费... 相似文献

中国是世界所公认的"陶瓷之国",早在3000多年前的商代,河南安阳就有原始青瓷出土。其烧成温度在1000℃以上,釉色以青、绿为主,釉层薄,产品欠火候,故只能算是原始青瓷。世界上公认的最早的瓷器—浙江上虞小仙坊窑址发现距今1900多年(东汉)的青瓷器,烧成温度达1310+20℃, 相似文献

在中国陶瓷史研究中,国内外诸多陶瓷学者都把越窑放在十分重要的突出地位,特别是中国周边的学者,比如日本学者就将浙江青瓷称作"大越窑"。长期以来,越窑被认为"诸窑之冠"地位神圣不可动摇,越窑一叶障目的现象不可忽视。笔者试图选择从横向维度"关于越窑是‘青瓷之源’的观点及其质疑"和纵向维度"越窑只是代表浙江青瓷其一个时代其产品的特色与文化,浙江青瓷文化是多元文化"进行探讨、研究和分析,从而重新审视并端正"越窑"在浙江青瓷中的地位,辨析两者之间的关系。 相似文献

景德镇湖田窑窑址的南宋、元地层出土了类吉州窑、类建窑以及自具特色的黑釉瓷片。本文通过研究它们胎釉的化学组成,并与吉州窑和建窑黑釉瓷的胎釉化学组成进行对应分析,认为湖田窑宋、元时期也生产自己的黑釉瓷。其南宋、元堆积层出土的黑釉瓷中有吉州窑和建窑的产品,为当时各窑烧制工艺相互交流的佐证。湖田窑生产的部分黑釉瓷模仿了吉州窑的选料标准,应该是学习吸收吉州窑烧造黑釉瓷工艺的结果,这类黑釉瓷可能是南宋时期生产的。而另一部分黑釉瓷使用了质量较差的瓷土作为制胎原料,可能是元代时生产的。 相似文献

An important requirement for producing evenly dried timber (lumber) in a kiln is that the airflow is uniformly distributed throughout the timber stack. The airflow distribution within the timber stack of a semi-scale kiln, which has multiple fans, was investigated to determine the possible causes of any airflow non-uniformity. Airflow measurements along the length of the timber stack illustrated the importance of ensuring that each fan generates the same flowrate, and that end-baffles are placed on either side of the timber stack to reduce bypass around these edges. Airflow measurements down the height of the timber stack demonstrated the effects of a separation zone near the air-inlet face of the stack, which partially reduced the airflow through the upper portion of the stack, and of non-aligned boards, which generated a saw-toothed velocity profile. Once the data had been smoothed to account for these effects, the down-stack velocity profile took on the expected form, with the maximum and minimum velocities at the top and bottom of the stack, respectively. Comparison of the velocity profiles at the air-inlet and outlet faces of the stack indicated a significant redistribution of the flow through the stack. The prediction of a one-dimensional model of airflow in a kiln was shown to be in good agreement with the smoothed experimental data at the air outlet of the stack. 相似文献

中国陶瓷艺术源远流长,而黑釉瓷器在宋代发展到鼎盛时期,建窑烧制的建盏更把黑釉瓷推向了厉史的巅峰.而建盏的发展又离不开中国的茶文化,二者相互促进、相互依存.饮茶的习俗使建盏成为中国陶瓷史上的一朵奇葩,而建盏又把中国茶文化推向历史的潮流.本文从建盏的文化渊源、宋代茶文化的内涵、宋代建盏的“器”对“道”的文化承载这三方面探讨宋代建盏与茶文化的关系. 相似文献

To establish a kiln drying schedule for beech (Fagus orientalis) lumber, 5-cm-thick boards were kiln dried down to a final moisture content of 8%. Three replications were made utilizing three kiln schedules of T5-C3, T5-C4, and T6-C4. With due attention to the effect of thickness on wood drying intensity, the t-test showed no significant difference between the thicknesses of the three drying schedules at a significance level of 99%. Therefore, the results of this study can be applied for 5-cm-thick boards. The primary dry bulb temperature in each of the three schedules was adjusted to 41°C and the final dry bulb temperatures were adjusted to 71, 71, and 82°C, respectively. The schedule offering the shortest drying time for the desired quality was chosen. Specific gravity and dry specific gravity were measured as 0.52 and 0.61, respectively. Longitudinal, radial, tangential, and volumetric shrinkage were 0.46, 5.8, 10.2, 16.48%, respectively. The extent of defects including crook, bow, twist, and three longest surface checks of the lumber was determined for each drying schedule. Quality control graphs were used to analyze the lumber defects in order to determine the best drying schedule. Analysis of the results indicates that with either of three kiln schedules the extent of defects before and after drying was not statistically different. However, the distribution of defects in the third schedule (T6-C4) was more uniform with respect to the average line compared to other two schedules. At the end of this schedule, a 17-h equalization and 24-h conditioning treatment is recommended. 相似文献
