조브로 : 업로드한 영상을 보면서 기능장 필답 준비 했는데 이번 시험에 합격 했습니다.
정말 많은 도움 되었고 감사합니다!
도금충 흐익 : 권총에 흑착색 처리했었는데 냄새도심하고 온도도 140이상에서 처리하니 여름에 작업하는데 힘들엇던기억이있네요ㅎㅎ
샌드표면에 흑착색처리가 더잘되서 샌드처리도힘들엇네요ㅠㅠ
김영민 : 흥미로운 정보 감사합니다.
SDJ : 스테인레스강에도 동일하게적용되나요? 그렇지않다면 주원료가 어떤게 들어가는지 알 수있을까요?
Jinsoo Kim : 혹시 알루미늄에 아노다이징 말고 이런 식으로 습식 흑색처리도 가능할까요?

코카콜라로 산화피막 / Knife coating with coca cola

산화현상을 이용한 나이프에 코팅을 만드는 방법입니다.
greennich : 산화피막이 생기긴 생기네요, 저도 이 영상보고 피막을 입히는 중인데, 피막이 고르게 나왔으면 하는 바램입니다. 저도 먹다 남은 콜라로 도전 중입니다. 영상이 좋읍니다. 잘봤습니다 감사합니다
jordan kim : 코팅은 모르겠고 , 저렇게하면 녹제거에는 효과가있습니다
구연산탄물에 녹슨철넣으면 자동으로떨어져나갑니다
수일에서 심한녹은 일주일이상걸릴때도 있어요
정택 : 이게 코팅이 맞나요?

How to Mix A Black Iron Oxide Stain for Lowfire Ceramics- A Guide for Teachers

This video is intended for teachers or someone who wants to mix up a lowfire iron oxide. This is what I use for my Ceramics I Themed Coil Pots in lieu of traditional glaze- (as glaze obscures much of the detail)

Here is a list of a playlist of all the videos in the Ceramics I Themed Coil Forms:

In this video, I mix up a lowfire black iron oxide. I use the Frit 3195 - which is for lowfire temperatures. You can use a highfire frit for a highfire application. I purchased my frit locally from Cornell Studio Supply in Dayton Ohio. They are awesome- Here is their contact info:

I use a respirator in the video to avoid breathing in any of the dust from the powders as I am mixing. I do normally mix my dry ingredients outside, however, it was storming at the time, and I just needed to get it done inside.
Here is a link to a respirator similar to mine:
Respirator for Dust- must be well fitting-

The two powdered ingredients are FRIT 3195 and Black Iron Oxide. Below are the links from Cornell’s website:

https://cornellstudiosupply.com/product/black-iron-oxide-1lb/

I am using about a 1:1 ratio of the oxide and frit- but have done as much as 2x the oxide as the frit. It must sit for 24 hours to really absorb, and then if after that time it looks weak, I can add more oxide and mix. Ultimately, it should look like you have dipped a piece in india ink.

We are using Standard 103 clay for this exercise. It is lowfire and grogless red earthenware.

I am a public high school ceramics teacher at William Mason High School in Mason, Ohio. (Mason is currently the largest high school in Ohio!) As a potter, I have been working in clay for over 30 years, and I have been teaching for over 28 years, the past 20 have been specifically teaching high school ceramics. I love what I do! I have my own studio in my home basement, where I work on my personal pottery for my Etsy site;

Juliet Cutler : I want to mix an iron oxide stain to brush on and sponge off bisque. I'll fire to cone 6. I'm wondering if you still recommend this technique for mid-range? Would frit 3134 or 3195 work for this? I'd also be mixing a much smaller quantity. From your video you are mixing equal parts oxide to frit, but do you have a recommended ratio for dry ingredients to water?
Cyndi Hedden : For the final firing, can I put glazed pieces in the kiln with the dipped Iron oxide? I also teach HS art at Margaretta High School in Ohio- we did this project with my Art I students and it turned out great. Thanks for sharing.
Scott McCormick : I use the following formula: 2/3 dry clay trimmings, 1/3 black iron oxide. Put into container and then add water and mix with immersion blender.
Felicci Dela Pena : Will I get the same results for Cone 6 firing? I understand that sometimes Black Iron Oxide turns red-ish when fired
Kazia Ginsberg : What would you say the ratio of each is? Thank you!
