建水紫陶的最后一道工序是打磨,这是一道纯粹的力气活,当然,要打磨得好,也是需要很纯熟的技巧的。但是因为这道工序实在太考验耐心和吃苦精神了,所以力气活往往留给人们更多的印象。

The last process of Jianshui purple pottery is grinding, which is a pure work of strength. Of course, to polish well, it also needs very skilled skills. But because this process really tests patience and the spirit of hard work, so hard work often leaves more impression on people.

鹅卵石打磨的时代就暂且不说了,那个难度比我今天要介绍的这种打磨方法要难上十倍。现在比较多的打磨方法是先用喷砂机将火皮去掉,然后用毛巾或其他棉布抹上金刚砂,包裹紫陶成品打磨一道,再用不同的目数的打磨轮进行打磨。

Let alone the era of cobblestone grinding, which is ten times more difficult than the grinding method I’m going to introduce today. At present, the more common grinding method is to use sand blasting machine to remove the fire skin, and then use towel or other cotton cloth coated with emery, wrap the purple pottery products and grind them together, and then use different mesh number of grinding wheels for grinding.

功率高、气压充足的喷砂机效率是比较高的,握住喷管,均匀喷除紫陶表面的火皮。有些喷砂机功率不高或者空压机提供的气压不足,就需要人工不停的踩喷砂开关;一只脚站着,另一只脚去控制喷砂开关,就算是长期操作的人也会双脚疼痛,就更别说刚学操作的了。

The efficiency of sand blasting machine with high power and sufficient air pressure is relatively high. Hold the nozzle and spray the fire skin on the surface of purple pottery evenly. Some sandblasting machine power is not high or the air pressure provided by the air compressor is not enough, so it is necessary to step on the sandblasting switch manually. Standing with one foot and controlling the sandblasting switch with the other foot, even those who have been operating for a long time will have their feet ache, let alone those who have just learned to operate.

对于器型比较规整的紫陶,用棉布抹上金刚砂,包裹打磨紫陶是速度相对较快的方法。这种方法打磨出来颜色均匀,且不易损坏紫陶。金刚砂的另一个作用是用于磨壶盖,紫陶壶与壶盖刚烧出来一般不会完全密封,需要借助金刚砂不断转动壶盖,打磨至完全密封。

For purple pottery with regular shape, it is a relatively fast method to polish purple pottery with cotton cloth coated with emery. The color of this method is uniform, and it is not easy to damage the purple pottery. The other function of emery is to grind the lid of the pot. The purple pottery pot and the lid will not be completely sealed when they are just burned out. It is necessary to use the emery to continuously rotate the lid and grind it until it is completely sealed.

我们平时所说的亚光、亮光等不同程度的打磨效果是由打磨轮的目数(粗细)决定的,目数越高、磨轮越细、打磨次数越多,打磨效果越光亮;目数越低、磨轮越粗、打磨次数越少,打磨效果越粗糙。这也就是为什么同样的紫陶,亮光要比亚光贵一些。

What we usually call sub gloss, bright light and other different degrees of grinding effect is determined by the mesh number (thickness) of the grinding wheel. The higher the mesh number, the finer the grinding wheel and the more times of grinding, the brighter the grinding effect will be; the lower the mesh number, the thicker the grinding wheel and the less grinding times, the rougher the grinding effect will be. That’s why the light of the same purple pottery is more expensive than that of the light.

使用磨轮打磨时要保持通风或者安装吸尘器,打磨时会产生大量灰尘,对人体造成伤害;同时,也要控制好打磨的力量和速度,一方面保证打磨效果,另一方面避免打磨时受伤。

When grinding with grinding wheel, ventilation should be maintained or vacuum cleaner should be installed. When grinding, a large amount of dust will be generated, which will cause harm to human body. At the same time, the force and speed of grinding should be controlled to ensure the grinding effect and avoid injury during grinding on the other hand.
