Color Case Hardening

<< < (4/6) > >>

75Plus:
Without a variety of charcoals there would be very little color. The more types you can use the better the result.

An airline submerged in the quenching tank, generating lots of bubbles, will also improve the color.

I just have to quote this becasue I miss read it. For some reason I read airline as "airliner". I wondered why you need to submerge an airplane to get bubbles. I guess 9:00AM is a bit eary for the brain to function properly.  :lol:  :lol:

Powder Keg:
Yea Bernd. Just think how big the tank would have to be :lol: :lol: :lol:

Jonny:
How about some results.

Just a semi controllable heat source is adequate but can be hit and miss.
Smith and Wesson dont use any charcoal, just pure heat and a hush hush sealing process.
The old English actions are a different process only a few know how and wont share. Bone meal? Kilns?

Fergus OMore:

A lot of the 'oldies' used old engine oil, common salt - and nitrates. Probably they simply 'pissed' on some jobs to get colour.

We now live in one of those clinically clean worlds but in another world- not so long ago, areas collected human urine, dried it and it went for export.

Most of us have heard of 'carrying coals to Newcastle' but Newcastle's second most important export wasn't coal or machinery or ships, it was 'piss'

Continuing the use of leather, doesn't anyone know how it was tanned?  It was probably done in 'dog faeces'.

I'll leave it at that as some will already be quite horrified.
