Hagi-ware has a specific feature that other potteries
don’t have. That is what is called “Hagi-ware’s color changing”.
That means, if
you continue using Hagi-ware, the color changes gradually. The reason is as
follows; the clay used for Hgi-ware is not so fine and has low pyrometric cone equivalent that firing
only once is not enough to make Hagi-ware stiff. Because of this fact,
sometimes glaze is covered with the wares.
With the use of glaze, the
difference of shrinkage ratio between glaze and clay makes chaps when firing
completes. Clay has some water absorbability and water get through from the
chaps. When you pour alcohol or tea, the components bond to the ware. This
gradual change makes Hagi-ware’s color change. This is called “Hagi-no-Nanabake
(literally, the seven change of Hagi-ware)” in Japan. Although those color-changed
ware comes in handy because they are pleasant, even some users in Japan
misunderstand that the wares became filthy.

Do you notice something like cracks?
When I met some craftsmen making
Hagi-ware, many of them said “some users complain because they don’t know
Hagi-ware’s color changing”. They also mentioned “although the color changing
is the very feature of Hagi-ware, most of the users don’t know the fact”. What
was worse, some of them even said “foreigners can’t tell this authenticity”.
Through these experiences, I decided to
write the article about Hagi-ware’s color changing. I know that I can’t tell
the authenticity by only these sentences and some photos, but after you read
this article. I’d like you to ask something.
“Hagi-ware’s color changing”. Which do
you think, the wares are mere filthy, or beautiful ?
