about my expressive technique
釉描彩 技法と意味について

 

  
東京芸術大学長 人間国宝 故藤本能道先生が 色絵磁器に初めて釉下または釉上への釉薬での絵画表現、各種絵具での釉下着色表現等を施され 釉上のみの色絵磁器に深みを表現し「釉描加彩」と命名されました。
これに触発された私は 四日市萬古の中で「冬柴流釉描彩」を30年程前から研究作品発表しています。
 
「冬柴流釉描彩」とは釉薬で描き上絵具で彩る、すなわち陶土で制作した器などに 素焼き後藁灰釉で絵付けし その際墨絵を描くように筆先に必要に応じ水を含ませ 一気に筆を下し釉の厚みによって色の濃淡 立体感を、表し、1240度での還元焼成で生まれたその変化のうえに 更に上絵具で着色し800度で焼成したものです。

この上絵に使用する絵具は九谷絵具、万古盛り絵具、大手メーカーのハンドペイント絵具などです。この絵付け技法は萬古盛絵と違った奥行きのある表現、色絵磁器にない暖かさなどこれまでに無い独特の味わいを得ることができました。またこの「冬柴流釉描彩」に伝統的な萬古赤絵を加味した作品創りで地域性と個性を発揮できるよう努力しています
 
 Yuubyoukasai by Mr.Noudo Fuzimoto
藤本能道先生作の釉描加彩

 

The late Noudo Fujimoto, formally a living national treasure and President of Tokyo National University of  Fine Arts and Music, originated the “under and over” glazing technique to paint pictures on his porcelain works.  He tried many ways of glazing with paints to express subtle colours.  He became renown for painting with a delicate over-glaze style.  His love of nature was vividly expressed in his painting, and this powerof expression was so great that he named his style of painting on porcelain “Yuubyoukasai”. 

    I was greatly influenced by his work.  I have developed a way to express “Yuubyoukasai” not on porcelain, but o stoneware.  I paint pictures with straw ash glaze on my stoneware after biscuit firing.  My style of painting with glaze is very close to Indian-ink drawing.  I put glaze on one side of the brush, soak water on the other side, and draw. After placing the stoneware in reduction firing at around 1,240 centigrade, the picture vividly displays the colours and the appearance of solidity.

    After that, I begin over-glaze colour painting on each part of the picture.My pigments come from Kutani, Kyoto as well as those I select from othercountries.  I am able to create amazing expressions through this original technique with vivid colours, the appearance of solidity, and a warmth that doesn't exist in painted porcelains.  I have adapted this unique technique to my stoneware-making, and have nameditYuubyousai” in honour of Noudo Fujimoto.
