What is thermo oak? What is the recipe for heat treating? I'm coming up blank on google searches.

Have a look at this thread:

30 mins in a domestic oven. Main purpose seems to be to darken up the timber.

Interesting article. I once worked with some boards cut from old oak piling material that had turned a grey color from years in water and mud. The color had penetrated fairly deeply into the wood. It might have made unique looking fingerboards.
Hi Jim,
What were you going to use the "Thermo Oak" for?

I have some 'bog' oak fretboard blanks that I bought here in the UK, it's the the most dense oak I have ever come across and is as black as night with silvery black medullary rays showing - absolutely beautiful.

I got my blanks from http://www.exotichardwoods.co.uk/Woods_List/Bog_Oak.asp which actually come from here http://www.adamsonandlow.com/bog_oak/

Hi Clay - just being curious about alternate fretboard materials.
