    陶瓷与骨瓷有什么不同?

    骨质瓷经过高温素烧和低温釉烧两次烧制,成为白度高、透明度好、瓷质细腻、釉面光亮平整的瓷器,素有“薄如纸、白如玉、明如镜、声如磬“的美称。骨质瓷餐具不仅具有华美的外表,还具有维护人们健康的品质。骨质瓷是在传统的陶瓷原料中添加了兽骨粉后烧制而成的,胎薄透亮,具有较大的韧性。骨质瓷是绿色陶瓷的代言,釉中彩骨质瓷是将画面熔在高温通明釉中,而且画面不易磨损、不脱落,可当之无愧地称为“健康陶瓷”。
    陶瓷是由粘土、石英及长石等天然矿物原料按不同配方配制,经加工、成型及烧成而得,其化学组成取决于所用天然原料及配方,不同地区不同窑口的古陶瓷由于所用原料的不同,配方的不同以及烧制工艺的不同,其胎釉化学组成、显微结构及物理性能就会有各自的特点。如果收集不同窑口发掘时有可靠地层年代的陶瓷标本进行系统地研究,把积累的数据资料如化学组成数据(包括主次量元素含量以及微量元素含量)建立数据库,并用适当的处理方法,譬如多元统计分析等方法对数据进行处理,找出具有特征意义的规律。对要鉴定的陶瓷的化学组成、显微结构、物理性能以及烧制工艺等方面进行研究,并将其化学组成数据与已知窑口和年代的古陶瓷的化学组成数据进行比较处理,再综合显微结构、物理性能以及烧制工艺等方面的信息就可能对陶瓷作出鉴定。
