> we've been using methyl alcohol sold as gas line anti-freeze. I've never heard of such a thing. And here I was, considering a move to Canada. Forget it, buddy. :-)
Yellow may also signal the presence of sodium, which can be added to impart a visible flame, as a safety precaution. Adding a pinch of baking baking soda to your meths bottle can preclude paint or bodily damage due to invisible spill fires. From what I've heard, this practice doesn't affect the performance of the alcohol. So, that yellow flame may not be "bad" impurities, but "good" impurities. But we were talking about methylated (denatured) ethyl alcohol, right? Methyl alcohol is pretty nasty stuff, from what I'm told, and it's difficult to buy over-the-counter here due to its noxious properties. regards, -vance- Vance Bass Albuquerque, New Mexico, USA Small-scale live steam resources: http://www.nmia.com/~vrbass
