Interesting.

 

I wonder how they deprive the wood of oxygen during cooking?...argon maybe???

 

This sounds very similar to what Gibson are doing with thier "Baked Maple" boards they are using to replace Rosewood on some of thier guitars

 

Could you provide a link for Coal-Tone guitars?

 

Seems liked it is more baked than cooked. Definitely not grilled or especially boiled. Not pan fried either.

 

My thoughts are that I can't stand reading red text on a black background.

It's heated to 300 degrees...

No website yet, some guitar models available at Boutique Tone in Montreal and you can inquire about the necks through us. basically your shape Tele or Strat with your selected fret size and material, select for vintage or modern size keys and finish is $320.00 shipped in Canada.

Thanks

Well we will have to change that just for you then. it is our goal to be like everyone else after all.

All the best.

Nice, stay classy Loudguitars.com.

That won't be necessary lol. I didn't mean to offend you, but I guess sometimes I tend to shoot from the lip. Having used baked maple myself, I'm familiar with it. I think it's good stuff, great for necks and fretboards, looks great and feels great too. Hope you sell lots of it. All the best in your endeavours.

Definitely "roasted". Wink!

 

Pretty guitars.

They must have a system to avoid case hardening the timber, which is what usually occurs when you kiln at higher temperatures. The outside cells of the wood dry quickly locking moisture inside and compressing the cells in the middle. Working case hardened wood can be a lesson in the forces of nature since it will warp, cup and twist when cut. I've heard of one process where they microwave the wood to break down the cell structure and then put it under a lot of pressure to force out moisture like squeezing a sponge. Apparently they can turn a round stick into a square piece of lumber without cutting. I don't think this is what they're doing though.

 

Shudder @ the word casehardened......been there....

I dug a bit this morning. The wood is actually called Torrefied. It's a step after the usual kiln process. It is then basically put in an autoclave with low oxygen. I think it was originally developed for proccesing wood pellets

Perhaps I am mistaken, but I understood the process for curing wood for musical purposes is more about trying to preserve the cell structure. In other words, wicking the moisture from the cell without collapsing the cell structure so that it hardens into a microscopic resonant chamber. I remember reading one of the problems with rapid heating, such as in a kiln, was the damage it caused to the cell structure. In other words, the curing process is more than just drying the wood, it is drying the wood in a manner that preserves resonance.

So are guitar companies and luthiers ordering "torrefied" wood but still having to tap test it for sonic quality? Is all the "torrefied" wood being delivered more musical or just more stable? Not trying to split hairs here, but it seems to me that the torrefication process has more to do with stability than musicality. Or is musicality one of the happy accidents that occurred as a by-product of torrefication? Just throwing it out there for discussion.

 

@cwittler........I doubt if there is any use of this stuff on acoustic or hollowbody guitars ie " tap testing tops" It's the stability that they are looking for especially necks. I can see a few advantages. Cool colour ( no amber dyes to age ) and being that dry would an 8% mc piece of wood absorbing back up to 12% in a damp time of year. If the piece is lower than gives you some more time to work or not work with the piece.

Don't forget that there is an extra marketing edge going on here. This process was not developed by musicians I am sure if regular kilned wood didn't work Fender would have stopped using long ago.


I just found this claim on a flooring site
"• Dimensional stability: Torrefied wood will not shrink, swell or warp with changing weather and moisture conditions. It is therefore ideal for precision applications such as furniture, doors and windows."

No offence taken, we are not selling any of this stuff just helping a local guy out. They really do feel amazing and very resonant.
Thanks

Well few things:

I tried 2 prototypes of the acoustics and all I can say is unbelievable tone qualities. Video soon.

Re-absorbtion is so very temporary and it requires the wood to be directly exposed to moisture for a long period, the pieces used are selected as guitar stock and already dried. When it comes time to shape them they retain .4 to .6%.

Marketing: well yes but not unreasonable pricing for a alternative, it is nice to have choices and these pieces are definatly choice.

"• Dimensional stability: Torrefied wood will not shrink, swell or warp with changing weather and moisture conditions. It is therefore ideal for precision applications such as furniture, doors and windows."


Well there you have it: Why would a floor company venture into the ultra precision of guitar building, it states very clearly will not shrink, swell or warp with changing weather and moisture conditions. Especially ideal for an acoustic.

The Two guys involved with Coaltone have dedicated years of their lives and are both Musicians and enthusiasts.

Peace.

I discussed that with Mike actually and his answer was that it "was" a happy accident that there was evidently more resonance and snap at least with the maple. It was Guthrie Govan who further convinced me that there was a difference in tone and in his case the choice was completely based on travelling with one guitar and needing stability.

The big guy's will start using this at an up charge, perhaps in custom shop models to start.

Some of the know Boutique guys are already using it; Suhr being one of them.

Peace

 

I found "cooked maple" at a wood store in Washington a few years back. I had no idea what it was, bought some just because it was "something different".
Ended up making a strat body out of it. Oops.
I'll be going back for more and this time I'll be using it for necks.

 

I can't imagine there being much oxygen in any heated, sealed area. So is this something that could be done, even to a lesser degree, in any oven or kiln? How much of a secret process is this?

Probably not too secret... just expensive for that autoclave. Kilning lumber is kind of an art though...which is still the beginning process.

 

As long as it goes with a good marinara sauce and some grated romano, I'd be happy.

That quick read over that I did suggests that what happens is the natural oils/resins will set in a sealed environment in a manner like a ceramic. Materials Science is an interesting science; tells us things like how a car in a collision behaves like a fluid and how a body in collision behaves as a solid.

 

I'm aware that most industrial processes can be duplicated in a home environment. I was thinking of a high school science experiment type of setup. What sort of temperatures might be involved?
