SOMETSUKE (cobalt blue decorated porcelain) 染付って!?


SOMETSUKE (cobalt blue decorated porcelain) 染付って!?


SOMETSUKE is cobalt blue decorated (cobalt blue underglaze) porcelain. BULE-AND-WHITE porcelain is fit for food that is mostly brown or green. So traditionally, SOMETSUKE has been popular in Japan.



Originally natural gosu pigment (cobalt with manganese) was used. However, mainly chemically manufactured gosu is used to prevent the color from running.


 Artificial cobalt has been used more and more in recent years. The main ingredient of gozu is cobalt oxide, which turns blue-purple when oxides such as iron and manganese are present. In Japan, a little of cobalt oxide was in Seto, but most of cobalt oxide was imported from China.


もともとは、呉須と呼ばれる天然のコバルト化合物を含む青緑色の鉱物を水に解いて絵の具を使っていました。近年は人工コバルトが多く使われています‼︎ 呉須の主成分は酸化コバルトで、鉄やマンガンといった酸化物が多いと、青紫色になります。日本では、瀬戸で少しとれましたが多くは中国から輸入していたそうです。




In the Yuan and Ming dynasties, gosu was imported from Asia. After the late Ming dynasty, minerals known as "earth blue" and "stone blue" produced in China were used.


Mainly Hasami supplied cobalt blue decorated (BULE-AND-WHITE) porcelain for domestic and Europe.


染付けは、有田や波佐見で国内外に向けて多く作られていました。現在は、呉須はコンゴ共和国から産出されたものが、 世界のシェアの多くを占めていて、大手商社を通して有田では使われてれているそうです。


近代以前には、いろいろな藍色があったのですね‼︎ 派手で発色が良いものが好まれるときもあれば、派手すぎてダメとか好みも変遷したようです(^^)
