Any ideas where to order?

Purchase Perfumers Alcohol (specially denatured alcohol), such as SDA 40-B which is a commonly available formulation. It's denatured with 0.12% t-BuOH
and denatorium benzoate. If you buy less than 5gal in a year, you do not need an ATF permit. While the tBuOH is going to be impossible to remove, it
shouldn't affect a whole lot. I think it is mostly present as a taggant to detect diversion of the product for human consumption which would illegally
sidestep taxes on it.
Alternately, go to the liquor store, buy some everclear, and work it up with CaO followed by reflux/distillation from Mg turnings and iodine.

^^^^^^^^^^^^^^^^
I presume this is denatured but couldn't find an MSDS for it...................
Any idea what the denaturants are.................. Methanol....................?

It's supposedly 97% pure and only contains bitterent – to stop people converting to alcohol.

Looking at "fireplace ethanol" (a product category I did not know existed until just now) on US eBay, and Googling for fireplace and "bio ethanol"
MSDS it looks like all the brands are marked E100, and claim to be "pure denatured alcohol" and the MSDS's generally indicated ethanol >90%, IPA
5-9%, and Denatonium <1%, and some "proprietary ingredient" < 10%. Exposure limits listed for this "trade secret" ingredient suggest that it is
safer than ethanol.
It appears to be anhydrous. As a fuel, it is a lot cheaper than perfumery ethanol (though the perfumery ethanol has a definite composition, and is
nearly all ethanol).
Might be good for a lot of uses, if some IPA and Denatonium are not a problem (that "proprietary ingredient" is a wild card though).
