Denatured alcohol is alcohol which has been adulterated with additives which will make you sick if you drink it, and/or make it unpalatable. -------------------------------------------------------------------- Damn, I -knew- that. I don't know where the H* I got the water bit. Spent some time in a analytic lab. Harry K |

Dolby might have said it once. So did Roddy. Listen to the crappiest album Faces ever recorded, "Coast to Coast Live". You know; the one with 'stellar' bassist Tetsu Yamaguchi (or something like that - who the hell *cares* how it was spelled?). As they're fumbling through the setlist, Rod says what I said he did. -- C.R. Krieger (Haven't forgotten *that* much!) |

For the folks that use 2-5mL each use, and open the bottle twice a week, I'd say that those folks discard about half a bottle each time. So there's some math to be done there, but I'm way too lazy.

Ask me about the P-Chem classes I took so long ago. I can't even remember the class titles. HAND, E.P. |

Not to mention gallons of various chlorinated hydrocarbons ... > Day-to-day and theoretical minutae have a way of disappearing. Ask me > about the P-Chem classes I took so long ago.
