Thank for providing instruction on glazes. It would be nice to see more for better understanding of glaze chemistry.

[@shujicodama8144]

Thank you for watching. I would like to continue posting videos about glazes and pottery.

Excuse me sir ，Could you tell me the weight ratio of iron oxide, wood ash and feldspar? Thank you very much 。

Hi, is it possible to give the percentage of the materials, ash/ feldspar/ red iron oxide That would be really appreciated Thanks

やっぱり説明付きわかり易いです。ありがとうございます！ もしチャンスがありましたら、例えば「長石というのはこういう役目をします。そして灰はこうです。◯◯はこうです、だからこれぐらい入れます。」的な事を教えていただけると非常に有難いです。気長に待ってますのでよろしくお願いします♪

こちらこそ、この度もご視聴ありがとうございます。 なるほど！ そのような説明付きの動画も、今後作っていきたいと思います。 今はまだどのように動画を作っていくか試行錯誤中ですので、とても参考になります。 ありがとうございます^_^

I am glad I found your glaze mixing and application video. In reply to a question you had mentioned this is an Oxidation glaze. What cone do you fire this glaze? Thank you for sharing your methods so generously.

[@shujicodama8144]

コーンは使用してなくて、色見を出す方式で焼いてます^_^

[@overlycranked8674]

@@shujicodama8144 Thank you for replying to my question. I understand the glaze in ceramics very well. I am in fact a ceramic worker. I watched all your videos to find this one. Now I understand you glazing method. Perhaps my question was not translated correctly for you. I had asked about the " temperature " you fire your glazed pots? In the western countries we measure the heat work in the ceramic kilns with " cone levels " and mark it with " ∆ " or simply a " ^ " and a number ( e.g ∆10 or 10^ ).

[@shujicodama8144]

Remove a small color sample from the kiln to check how well the glaze has melted. Because cones aren't always accurate either.

おはよう ちょっと聞きたいのですが、この酸化鉄釉は還元焼成か酸化焼成して黒くなります。 ありがとう Good morning I wanted to ask you something, this iron oxide glaze, to become black, is fired in reduction or oxidation Thank you Buongiorno Volevo chiederti una cosa, questo smalto di ossido di ferro, per diventare nero, viene cotto in riduzione o in ossidazione Grazie

[@shujicodama8144]

酸化焼成ですよ！

[@cretafralemani]

Grazie @@shujicodama8144

[@massimomanunza3215]

Reduction firing?

[@shujicodama8144]

This is oxidized firing.
