骨瓷和陶瓷的区别是什么?
1、原料不同:
陶瓷是以天然黏土以及各种天然矿物为主原料,原料中骨粉含量超过25%的瓷器为骨瓷。
2、工艺不同:
骨瓷烧制采用二次烧成工艺,温度在1200度-1300度之间,一般陶瓷烧制900度即可成型。
3、重量不同:
由于骨瓷硬度高,器型比一般瓷器要薄得多,因此同等体积的骨瓷要比陶瓷轻得多。
4、发源地不同:
骨瓷起源于英国,是英国皇家和贵族的专用瓷,而陶瓷发源于中国,历史悠久。
“陶瓷”和“骨瓷”的区别是什么?
骨瓷,是陶瓷的一种。因在其黏土中加入30%左右的食草动物骨灰(一般是牛骨粉)而得名,是由18世纪英国发明的。
由于骨灰的加入,骨瓷的硬度与透光度,强度高于一般瓷器,是日用瓷器的两倍。由于独特的配方和牛骨粉的加入,使瓷土中的杂质被消除,骨瓷显得更洁白、细腻、通透、轻巧,极少瑕疵,并且比一般瓷器薄,在视觉上有一种特殊的清洁感。骨粉的合量越高,黏土的成分就相对降低,在 *** 过程中就越易烧裂,在成形上需要更高的技术,增加了烧制难度,成品率较低,所以更加珍贵。
骨瓷色泽呈天然骨粉独有的自然奶白色。一般说来,原料中含有25%骨粉的瓷器则可称为骨瓷,但世界上公认的质地更好的骨瓷一般含有45%的优质牛骨粉。其中骨粉成分为40%以上,器具颜色则更呈乳白色,属高档骨瓷。
骨瓷和陶瓷的区别
骨瓷是于1794年由英国人发明的。因在其黏土中加入牛、羊等食草动物骨粉而得名。骨瓷色泽呈天然骨粉独有的自然奶白色。陶瓷是陶器与瓷器的统称,同时也是我国的一种工艺美术品,远在新石器时代,我国已有风格粗犷、朴实的彩陶和黑陶。——《百度百科》
骨瓷和陶瓷看似差不多,但是两者在原料上,工艺上,通透性上,吸收性上以及保温性上都存在着很大的不同。
一、骨瓷和陶瓷在原料和工艺上的不同
首先从原料上可以来鉴别骨瓷和陶瓷骨瓷的原料,主要是粘土、牛骨粉 *** 而成的,而陶瓷的原料则是由高岭土、瓷石 *** 而成的。而且在工艺上两者也存在着一定的差别,骨瓷是由低温烧制而成,而陶瓷的 *** 温度相对来说需求比较高,因为陶瓷有着许多的颜料要 *** 成各种花纹,内部含有重金属,要高温才能 *** 。
二、骨瓷和陶瓷在通透性上的不同
从通透性上来区别骨瓷和陶瓷会发现在灯光的照射下,骨瓷全身透光性很强,并且没有杂质,因为内部骨粉含量很高,看起来就十分的透彻。可是陶瓷在灯光的照射下,并不是十分的晶莹剔透,反而会呈现出暗淡的光泽。骨瓷的声音相对清脆,陶瓷的声音相对低沉。
三、骨瓷和陶瓷在吸收性上的不同
从吸收性上来看,会发现古瓷的吸水率较低,所以比较容易清洁,也不会留下任何的杂质,只要用温水冲洗一下,就可以恢复原先的洁净感,并且骨瓷的保温效果也比陶瓷要好一些。
