Fire tempering.

Obviously not for the same reason, but does show it is not just an object made crudely for the purpose of killing. There is more to it. i find it all very interesting.

I think Tim, It could also be done in a localised area of the stick with large candle or even a butane gas torch...Leaving unburnt areas of wood. There nothing I can see to imply it was done during over a camp type fire scenario?

That is possible. What if they where also after the overall tempering. Simply burning the surface is not fire tempering. Also the people mentioned where no Larramie Loafers?

I agree burning is not tempering... I cant tell from photos if that piece is burnt or tempered though? if tempered , intermittent pattern seems strange?

I get the impression from the film I linked to in this thread..

That the fire tempering requires heating & smoking, to generally fast season & harden, by driving out moisture, rather than surface burning?

I've heard of some Kentucky Long Rifles decorated with fire using a cord soaked in flammables, wrapped around the stock and lit off .
The result is a striped look to the stock and forend of the gun .

I would suggest that correct terminology is "fire hardening", not "fire tempering".

The character of the wood is made harder by the skilled use of heat applied to the surface.

In working with steel, the tempering process is carried out after the steel has been hardened, and its purpose is to soften the steel so that it is not brittle and is able to be used.

Perhaps an argument could be mounted for the use of "temper", in that broad use of the word "temper" can be interpreted as to modify the state of something so that there is no excess in either direction, with wood treated by fire it is modified so that it is neither too soft, as in its natural state, nor too brittle as it would be with excess application of heat.

Very often lay people will refer to the heat treatment of steel after forging as "tempering", which is only the second part of the process needed to make it useable after forging.

With wood, the second part of the process after hardening is not necessary, so perhaps a more accurate use of language here might be "hardening", rather than "tempering" ?

Well fire hardening is perhaps a better term, but I wouldn't lose any sleep over the word tempering....

After all we are talking about timber not steel or glass....

The word origin for tempered is probably the latin tempor for time or season, heating the timber over a fire advances does that process... {not unlike the much more controlled kiln drying to speed the process.}

I guess that was an attempt to mimic the fiddleback maple look?

Yeah, I agree, use of tempering is no big deal, the reason I have commented is because when I saw it was about wood the use of the word confused me until I read further.

Roots are Latin>temperare,Old English>temprian,Old French>tremper(sense development).

Temperare is to moderate, tempo and tempor are related to time.

My apologies for being pedantic.

Good chat fellows. I have been looking at youtube for a demonstration video. Some lightly interesting stuff can be found, but none of the examples are anyway of a serious nature. Certainly not in the sense of fire hardening a whole club like the New Hebrides piece.
