掇球壶的来历?建水紫陶的收缩率是多少?

回答昨天陶友们提出的其中三个问题,如果你有什么问题,也可以在留言区提出来,我们一起探讨。

Answer the three questions raised by Tao you yesterday. If you have any questions, you can also ask them in the message area. Let’s discuss them together.

1、掇球壶是怎么来的?为什么取名叫做掇球?

1. How did the ball jug come from? Why is it called duoqiu?

答:许多壶友不明白一把壶为什么取名叫做“掇球”,这个根本不明白是什么意思的名字。

A: many pot friends don’t understand why a pot is called “duoqiu”. They don’t understand what it means.

实际上,掇球是从莲子壶的器型基础上得来的壶型,把莲子壶把下的耳朵去掉了。后来冯友庭与程寿珍师徒把壶脖子加高,盖更接近半圆型,壶钮也更圆,加上壶身的大圆,这样就像三个叠起来的球。

As a matter of fact, duoqiu is based on the shape of the lotus seed pot, which removes the ear under the lotus seed pot. Later, Feng Youting and Cheng ShouZhen raised the neck of the pot, the lid was more close to the semicircular shape, the button was more round, and the big circle of the pot body was added, which was like three stacked balls.

至于为什么取名叫做“掇球”,是因为“掇”字有连缀堆叠的意思,所以三个球叠起来的这个壶型,就被取名叫做“掇球壶”。

As for the reason why it is called “duoqiu”, it is because the word “duoqiu” has the meaning of continuous stacking. Therefore, the pot with three balls stacked together is named “duoqiu pot”.

2、紫陶器口有一些白色的物质是什么?有害吗?

2. What are some white substances in the mouth of purple pottery? Is it harmful?

答:这种白色物质是氧化铝,是一种常见的金属氧化物。几乎每一件紫陶在烧制之前都会在口边沿涂抹一层氧化铝粉,目的是为了防止高温烧制过程中盖子和口粘连在一起打不开。

A: the white material is alumina, a common metal oxide. Almost every piece of purple pottery will be coated with a layer of aluminum oxide powder before firing, in order to prevent the lid and mouth from sticking together in the process of high-temperature firing.

大部分的氧化铝粉在烧制出来后的整口这道工序中都会被磨掉,有一部分仍然会残留在上面。但是大家不必担心,氧化铝在生活中很常见,是无害的。一些铝制的餐具长期接触空气,表面就会生成一层氧化铝。

Most of the alumina powder will be grinded off in the whole process after firing, and some of it will remain on it. But you need not worry, alumina is very common in life, is harmless. Some aluminum tableware long-term contact with the air, the surface will produce a layer of alumina.

3、建水紫陶的收缩率是多少?

3. What is the shrinkage rate of Jianshui purple pottery?

答:与其他陶瓷相比,建水紫陶的泥料中硅、铝含量相对较小,可塑性和耐高温程度相对较低,烧成前后,其主要维度的收缩比约为14%~18%,不当的干燥、焙烧方式,都会造成陶坯裂损变形。

A: compared with other ceramics, the content of silicon and aluminum in the clay of Jianshui purple pottery is relatively small, and its plasticity and high-temperature resistance are relatively low. Before and after firing, the shrinkage ratio of the main dimensions is about 14% ~ 18%. Improper drying and roasting methods will cause cracks and deformation of the ceramic body.
