Hi do - magical Japanese fired red copper

[@mjenk20236]

That was an awesome class. Great instruction and the attendees were so interesting.

[@FordHallam]

Glad you enjoyed it!

Great timing. I wanted to use this technique on some mokume for a bowie I am making.

I've gotten patches like that when trying to anneal some cups I was raising. Never knew what was causing it.

[@jamesbarisitz4794]

Awesome colour change.

Ford Hallam is a master.

[@manatoa1]

That is extremely cool

I wonder if this will work on plain old copper as I need to make seppa , and I wonder how the borax works🤔 great work Ford

[@nickwoo2]

It works well on plain copper but not so on silicon bronze. I have been trying to get the bronze to go red bit all i get is a weak layer that flakes off easily.

I’ve used this method on fold formed copper that I recycle from old water pipes, and it works well. Interesting that Ford mentions it will work with plain water, that’s been my experience too. I do get better results using borax, though I don’t know the chemistry behind it. My thoughts are that it may form a fine layer of glaze on the hot metal, much as you find when it’s used as a soldering flux. That might either make the oxide layer stronger or do something to modify the reaction between the copper and oxygen that creates the red colour.
