An alternative way to construct a tsuba?

[Alex A]

It was this line below, im just thinking moisture got under the seppa, for some reason, over time.

 

 "In your case you need to define if there is the possibility that at the interfaces between the two metals there could be water, maybe condensing humidity or rainy water."

 

To me, it don't look like there is any coating on that tsuba, to me, its maybe plausible there has been some kind of reaction there, especially looking at the surface thats left.

 

Though what do i know lol, its just a proposal for folks more knowledgeable to consider it plausible.

 

I can vaguely remember Ford years ago talking about reactions to steel, though cant remember the details.

Here is a photo of another cast tsuba from the book "Tsuba collecting for the  beginner"

 

Also look at the pitting in both tsuba and the weird colour of the ategane.

Hi Tony!

 

Thanks for the interesting information.  Much appreciated!

 

But I was just floundering around on the internet again and I found this when I inquired if molten cast iron can be poured onto steel-

 

“AI Overview

Yes, molten cast iron can be poured onto steel, as long as the steel is properly prepared to withstand the heat and potential thermal shock; however, this is typically done in controlled industrial settings to create specific composite materials or for specialized applications, as the different properties of cast iron and steel can lead to issues like cracking or warping if not managed carefully.

Key points to consider:

 

Temperature difference:

Molten cast iron has a lower melting point than most steels, so the steel must be preheated to a suitable temperature to avoid rapid cooling and potential cracking.

 

Mold design:

When pouring molten cast iron onto steel, a proper mold design is crucial to ensure controlled solidification and prevent uneven stress distribution.

 

Application:

This technique might be used to create a bonded layer of cast iron on a steel component, providing wear resistance or improved surface properties.”

 

Interesting stuff! 

 

I have read that some tsuba craftsmen were like alchemists in how they could mix and fuse different metals!

 

Maybe something like that was done on the tsuba that I have pictured on my previous posts?  Or maybe not?

 

Just guessing here! 

 

But that tsuba does intrigue me and raises questions.

 

I will try to find out more when I receive the tsuba and can take pictures.

 

Onward!

Hey Dan, 

 

Is this you?

Hey Derek!

Yes!  But don't tell anyone.

Just eliminate your post!

Ha, ha, ha, ha, ha, etc!

Onward!

AI also supports that iron and steel will flake, especially after corrosion. Seems like the most logical conclusion
 

All the best,

from the book

Hi Tony, not sure if you have access to this book in Swedish?   https://archive.org/.../n1/mode/2up?q=tsuba   A large section of the book concentrates on tsuba.  Most of the images are rather poor but if you send me a PM. I can supply more up to date images.

A little dated but so is    [I should know ]
