    Jack,

    Here's the list of acronyms - http://www.familywoodworking.org/for...ad.php?p=68849 - and DNA is denatured alcohol, which a lot of turners use to help dry their rough turnings.

    DNA = denatured alcohol

    Usually used by turners to soak bowls in to dry the wood before finish turning them.

    Jack you can get denatured alcohol at the local hardware or lumber yard in the paint section. The stuff you get at most drug stores is not Denatured and IIRC is only 30% alcohol. Denatured is straight alcohol with a additive added to make it undrinkable.

    DNA is Ethanol with additives to make it undrinkable.

    Most DNA that is sold at a Big Box store is between 90%-95% alcohol

    If you know somebody with a still that will sell you "White Lighting"...

    Undrinkable? Hick!

    Ok, I was going to try and answer the #2 question about #2, but I'm not well versed enough to express my feable thoughts. I found this site you might look at. Explains it pretty well.

    Thanks everyone, but so far no one has explained how to use it, for how long, and if you mix it or not.

    Paul, I thank you for the link, but it lead me to a site about Beautiful Iron . Thanks Jack

    Jack - the following links should provide you with all the info about the DNA process that you will ever want or need. If you have any questions after checking the links out - let us know and we'll all figure something out!

    In a nutshell, it's typically used straight (not diluted or mixed). A rough-turned green wood piece is submerged in a bucket or pan of DNA for anywhere from 18 hours to a few days. Most folks soak for about 24 hours, but going longer is not a problem. After the piece has soaked, it is removed from the DNA bath and wrapped in a few layers of paper, A lot of folks use newspaper or brown paper bags. This helps prevent the wood from drying too fast, but still allows it to breathe. Everybody has their favorite way to wrap the soaked piece...some wrap just the outside of the bowl and leave the inside exposed to the air, others don't wrap at all and instead place the piece is a paper bag (sometimes with more wood shavings in the bag as well). I think some people have a special dance they do while waving a string of chicken bones and chanting ancient Inca woodworking prayers. Me, I wrap the whole thing pretty loosely in about 4 or 5 layers of newspaper, sometimes leaving some of the inside of a bowl unwrapped. It seems to work, so I keep doing it that way.

    The end result of all this extra effort is that the rough-turned piece dries faster than if it had been left to dry naturally. Typically, the DNA-soaked piece will dry in 3 to 4 weeks, whereas if it was not soaked, it might take up to 6 months to dry. It is also theorized that cracking and warpage are minimized by soaking in DNA, but I don't know of a good way to prove that.

    Dave Smith has done a lot of studying DNA soaking. Here's an article on WoodCentral for more info:
