建水紫陶的烧制方法有哪些?液化气倒焰窑、电窑、柴窑

目前主流的烧制方法有三种:

There are three main methods of burning at present

一、液化气倒焰窑使用最广泛

1、 LPG downdraft kiln is widely used

以液化气为燃料,喷火嘴对称安装在燃烧室的底部边沿,排烟道设置在底部正中。点火后,火焰顺着燃烧室两边网上蹿,至顶部后在烟囱的吸力作用下,火焰先向中间聚集,再向下倒焰贯穿整个燃烧室进入排烟道,再顺着烟囱排出燃烧室。

Using liquefied gas as fuel, the nozzle is symmetrically installed at the bottom edge of the combustion chamber, and the smoke exhaust duct is set in the center of the bottom. After ignition, the flame leaps along the net on both sides of the combustion chamber. After reaching the top, under the suction of the chimney, the flame first gathers in the middle, and then falls downward through the whole combustion chamber to enter the smoke exhaust duct, and then exits the combustion chamber along the chimney.

液化气倒焰窑有较大的窑内空间,一般用于烧制大型的紫陶缸等,出货量较大的制陶厂,也会选用液化气倒焰窑烧制茶壶和茶杯等小件。

Liquefied gas downdraft kiln has a large space in the kiln, which is generally used for firing large-scale purple pottery jars and so on. In ceramic factories with large shipment volume, liquefied gas downdraft kiln will also be used to burn small pieces such as teapots and cups.

二、电窑烧制最稳定

2、 The most stable firing in electric kiln

电窑通过燃烧室周围的炉丝提供温度,整个烧制过程都可以事先全部设定,让烧窑过程按照自己设定的程序去完成,操作最简单,安全性也最高。

The electric kiln provides temperature through the furnace wire around the combustion chamber. The whole firing process can be set in advance. The kiln process can be completed according to the procedures set by itself. The operation is the simplest and the safety is the highest.

电窑的窑内空间一般比较小,有的一次仅可以烧制10到20件紫陶壶,一般出货量不多的小型陶艺工作室,偏向于使用电窑烧制。

In general, the space inside the electric kiln is relatively small, some can only burn 10 to 20 pieces of purple pottery pots at a time. Generally, small ceramic art workshops with a small shipment tend to use electric kilns.

三、柴窑烧制最神秘

3、 The most mysterious way to make wood kiln

三种烧制方法中,柴窑最古老,也最神秘,几乎每一个窑口都有自己的故事。从烧制周期来看,柴窑所需时间最长。以木材为燃料,在温度和火候上不好准确把握。

Among the three firing methods, Chai kiln is the oldest and the most mysterious. Almost every kiln has its own story. From the firing cycle point of view, the firewood kiln takes the longest time. Using wood as fuel, it is difficult to accurately grasp the temperature and temperature.

柴窑的空间可大可小,大的如龙窑,一次可烧制数千件陶瓷作品,小的如自家所建窑口,一次烧制小件一二百。总之,窑内空间可根据自己的需求去建设。

The space of a wood kiln can be large or small. The large one is like a dragon kiln. It can burn thousands of ceramic works at a time. The small one can be as small as the mouth of one or two hundred small pieces at a time. In short, the space in the kiln can be constructed according to its own needs.

柴窑的窑内布局和烧制方式会导致不同部位的热量差异较大,对于烧制的成功率和最终烧成效果影响较大。常见的会出现部分温度过高的情况,导致烧起气泡。而柴窑裸烧时,形成的自然落灰釉受到一部分陶友的追捧。

The layout of the kiln and the firing method will lead to the difference of heat in different parts, which has great influence on the success rate and final firing effect. Common will appear part of the temperature is too high, resulting in bubbles. When the Chai kiln was firing naked, the naturally falling gray glaze was sought after by some ceramic friends.
