- It's not fun with the usual firing. I want to bake a vessel with a more atmosphere!
Introducing the carbonization firing method to give to you.
It is a firing method that can be used for anything from electric kilns for pottery, kerosene kilns, and gas kilns.
Let's aim for an interesting baking together using rice husks and rice husks.
Of course, you may fail, but every time you try, the expression of the bowl will change, and you will surely be able to bake your favorite bowl.
A bowl that is baked without relying on glaze should be a gem.

that's really cool いつもありがとう
Thank you for your comment.
Thank you for always watching my video.
AWESOME!!! Can't wait to try for myself
Thank you for your comment.
Please try it.
Please tell me the result!
Wow nice, I was wondering if it was possible to get more varied results with electric kiln, glad to see this technique, thank you for sharing!
Thank you for your comment.
Even in an electric kiln, you can try various firing methods by using a fire box. Please try it as a reference.
I like it! Im excited to try with rice husks. I made a fire box, it is drying now.
Thank you for your comment.
You try firing rice husks, right? I'm happy.
I hope you will get good results.
@@kiraku-pottery thank you! Yes I am using rice husks. I am also trying to make a nuka glaze with rice husk ash. I love nuka glaze
Thank you for your reply!
You know "NUKA"!
Rice husk ash can be used as a glaze in the same way as straw ash.
I wish you success.
thanks for another amazing video. just wonder around how long do you bake/firing it ? and at what temperature? thanks for sharing
Thank you for your comment.
In my kiln, I fire at 1230°C for 16 hours.
Hi from Iwate. I am worried about the gas pressure if I close the lid tightly. Is there a problem with explosion? Thank you!
Thank you for your comment.
The gas pressure does not rise even if the lid is closed.
Gas escapes through the gap in the lid. It also smells when firing!
すごく興味深く見せて頂き良かったです。灯油窯でもできますか?
灯油窯でも出来ると思います。
試してみて下さい。
Hello, can I ask this skill will suitable with different clay? Or just only the clay that you used? And it need specific clay ?
Thank you for your comment.
I think this technique can be done with any clay.
However, please note that the color will change depending on the type of clay.
There may be little change with white clay.
Thank you so much
いつも勉強になる動画をありがとうございます！この焼きでは温度はどのぐらいでしょうか？？
コメントありがとうございます。
この焼成は1230℃で16時間焼成です。
格好良く焼き上がりますよ！
Omoshiroi..!!
ありがとうございます！
窯変もでしたが籾殻の姿に興味ありです。
籾殻の白と黒は燃焼度合の違いでしょうか？中心部の籾殻が黒いのは酸欠で不完全燃焼になったままだからでしょうか？
（だとすればサヤ内は強還元状態ですね）炭化は酸化焼成では難しいのでしょうか？・・・素人ですみません。
２度目が濃く出ているのはやはり炭素量を多く浴びているということですか？
コメントありがとうございます。
中心部の籾殻が黒いのは、仰る通り不完全燃焼だと思います。強還元かは微妙ですね・・・。
サヤの中にいれて、しかも茶碗と茶碗の間にある部分が黒いので、中で不完全燃焼の部分が出来ているのではないでしょうか？
2度目焼成が黒くなっているのは、器がより焼締った感があります。2度焼きした器の方がサイズが小さくなっているので、一度目の焼成はそれほど高温になっていなかったのでは無いかと想像しています。
もう少し焼成を重ねないと何とも言えませんが、そんなイメージです。
匣を買いました❗甲イカの甲も変化が有るらしいです。密閉するのは粘度が一番最適ですか⁉️
コメントありがとうございます。
密閉するのは粘土が良いと思いますよ～
@@kiraku-pottery 有難うございます。挑戦します。
The colour refired work is really nice! Thanks for showing the trials and error. Your videos are the legend!!!
Thank you for your comment.
What is a legend? I'm happy.
Please continue to refer to various videos.
炭化焼成を初めてやってみました。
籾殻と炭をまばらに入れて素焼きはせずやったのですが、下半分は黒くなり上半分が気泡がでてぶくになっています。
触ったらパリパリでやすったらぼろぼろと削れます。
ちなみにガス窯です。
原因とかわかりますでしょうか？
何でしょうね？粘土に不純物が多いのですかね？
炭を入れずにやればブクは解消されると思いますが、色の変化は出てしまいます。
同じ器を何度か焼成すると色味が深くなる傾向があります。
サヤに炭を多めに入れて炭化焼成したら、結構真っ黒になりました。 見込みに3号透明釉薬をかけたところは、グレーに仕上がりました。 還元と炭化で炭の量の加減は難しそうです。
そうですね！
還元については、少量の炭でも還元がかかります。そこに釉薬が加わるとさらに色々と難しそうですね！
炭化焼成については無釉でも良いと思います。
The rice husk will show a lot of smoke, When the pieces in the kiln?
Thank you for your comment.
I don't think that much smoke will be emitted when firing rice husks in a fire box. But it smells like it's burning.
Since it is fired in an electric kiln, it is expected that the rice husks will ignite at around 300 ° C to 400 ° C.
Thanks for your sharing.😍😍
They turned out really beautiful! I love the orange color! I'm excited to try it once I make my firebox :)
By the way, I don't know if someone reviews the subtitles, but I think around 10:39 when it says "unglazed" it should be "bisque" or "bisque fired". Sometimes translation is really difficult, especially with very technical things like this. I hope it helps :)
Thank you for your comment.
Firebox firing is recommended because it is interesting to bake.
Regarding translation, since we use google translate, the technical terms are often different. I would appreciate it if you could guess the meaning from the whole flow.
Thank you for telling me the word.
is this method of firing food safe?
Thank you for your comment.
There is no particular problem in Japan.
I don't know what it is in your country.
I like watching your videos. But I think it is better to translate 素焼 as "bisque-fired", and not "unglazed." Thank you!
Thank you for your comment.
In recent videos, it is bisque firing.
I'm sorry that my English is immature.
@@kiraku-pottery I wonder if I can use terracotta clay for the saggar. Thank you.
@@kiraku-pottery Your skills are very high!
I think that tool clay is cheap and good.
@@kiraku-pottery Thank you, but I don't understand "tool clay."... : (
