瓷器的意味

池莉

        ①只要日子一好,瓷器就是一个好东西。现在人们越来越觉得瓷器是个好东西了。

        ②比如许多人搬了新家或是装修房子,只要稍有余地,便会置一架多宝柜,架上最少不了的就是瓷器。瓷器的确是好看,其质地,造型,图案,色彩,没有其他什么工艺品可以媲美,实在是一件无可非议的雅物。一般的东西,单从名字上看不出太大的好处,房子就是房子,住人的地方。只有瓷器的名字取得讲究,如叫什么青花釉里红玉表春瓶的,简直就像欧洲古典女人的长裙。是绝不肯平铺直叙的,到处都镶了繁复的精致的华丽的花边,修饰出无穷无尽的意味。

        ③现在,瓷器毫无疑问是一件大雅之物。然而它是怎么来的?是做什么用的?这么往深处一想,就会发现瓷器原来是一个大俗之物。瓷器原来是作吃喝拉撒用的,最初脱胎于陶器。在汉代之前,一般都烧制陶器,它的发明和用途直接源于人类基本生活的需要。陶器发现的年代早,据说原始社会的燧人氏就会制造陶器了。人类懂得了使用火,用火烤熟的食物是烫的,这就要求使用相应的容器,于是各种各样的为生活服务的陶器便被创造了出来。釉是汉代发明的,有了釉之后,陶器便向瓷器大大地前进了一步。但是瓷器也仍然是用于实际生活的,等到在现实生活中足够使用了,人们的物质生活也比较丰富了,这才有少数人的艺术天分开始觉醒,更高的追求出现了。真正作为单纯欣赏对象的精美瓷器这才出世。这个年代就是我们民族历史上的鼎盛时期——唐代。

        ④唐代开瓷器艺术的风气之先,想必也是因为丰衣足食之后无所事事,便有了多余的精力去热乎艺术。那时候,一件精美的瓷器作品出来,人们便口口相传。传到社会上有钱有势的人那儿,他们就不惜千金购买了过去,藏入深宅观赏把玩,一帮文人骚客也为其吟诗作画。一来二去,瓷器的佳名传到宫廷,皇家也是凡人,对瓷器的喜欢也是有的,不喜欢也是有的,但是既然达官贵人这般青睐瓷器,在社会上又有了文名,皇家也难免附庸风雅,也欣赏把玩起瓷器来。瓷器贵入宫廷,反过来又刺激了社会。商人有利可图,他们便会投资瓷器工艺,工匠自然受到了极大的鼓舞,艺术灵感喷薄而出。就这样,一波波,一浪浪,推动着瓷器精益求精的创作,直到宋代的登峰造极。在几千年的时间里,大浪淘沙,肉腐骨存,瓷器终于完全摆脱了最初的粗陋面目,登堂入室,成了艺术品。

        ⑤尽管瓷器已经被公认为艺术品,但至今为止,用于吃喝拉撒的瓷器器皿还是用于吃喝拉撒,并没有因为成为了价值连城的艺术品而失去世俗性,世俗是瓷器厚实而庞大的艺术基础,在这个基础上,它才一步步登高,越来越好,艺无止境,美无止境。可见大雅寓于大俗,无俗也就无雅,不俗也就不雅,俗雅其实是一体的。

        ⑥再说了,即便是当年官窑出的夜壶,皇帝撒过尿,诗人写过诗,你就是不在乎它,不供在博古架上,不送给博物馆,不卖给文物商店和收藏家,依然拿它撒尿,它也就无所谓俗雅。它做一天和尚撞一天钟,尽自己的本色就是。这就好比一个人出了家,超尘脱俗,不在红尘话语中,自然又是一重清凉境界了。这是艺术和做人最难的境界,就是做到了别人也无从知道,因为它不再在任何媒体露面和喧哗,大众很快就忘记了它。只有在意外的或者偶然的某一刻,它与它的知音相逢,那一刻当然就是夺人魂魄,惊天地而泣鬼神的了。

There are many famous museums throughout the world where people can enjoy art. Washington, D.C. has the National Gallery of Art; Paris has the Luvre; London, the British Museum. Florida International University (FIU) in Miami also shows art for people to see. And it does so without building, or even a wall for its drawing and paintings. FIU has opened what it says is the first computer art museum in the United States. You don’t have to visit the University to see the art. You just need a computer linked to a telephone. You can call the telephone number of a university computer and connect your own computer to it. All of the art is stored in the school computer. It is computer art, produced electronically by artists on their own computers. In only a few minutes, your computer can receive and copy all the pictures and drawings. Robert Shostak is direction of the new computer museum. He says he starts the museum because computer artists had no place to show their works.

A computer artist can only record his pictures electronically and send the records to others to see on their computers. He can also put his pictures on paper. But to print good pictures on paper, the computer artist needs an expensive laser printer (激光印刷) . Robert Shostak says the electronic(电子的) museum is mostly for art or computer students at school and universities. Many of the pictures in the museum are made by students. Mr Shostake said the FIU museum will take computer art more fun for computer artists because more people can see it. He says artists enjoy their work much more if they have an audience. And the great number of home computers in America could mean a huge audience for the electronic museum.
