This what you were looking for?

Hardly worth getting all worked up over a couple guys going off on a tangent on a slow day, don't you think?

The sterno I remember was just methanol

HONESTLY.....................

 

I wish we could get away from Chemistry 101 and get back to using our talents ( if there actually are any extant)

to finding and improving techniques for producting quality PCB's at home with "non-exotic" materials like

iso alcohol and fingernail polish remover.

 

If we continue in the present direction, someone will post a method for using "heavy water" and

radio isotopes for PCB fabbing in our own, personal home-built radiation chamber!

 

Sterno????

 

Are you kidding???

 

Is there no moderator on board???????

 

Please Guys!

The methanol in denatured alcohol sold under the Klean-Strip S-L-X name "Thins shellac, cleans glass and metal. Clean-burning fuel for marine stoves."

 

The MSDS says it is 45-50% Ethyl alcohol, 40-50% Methanol, and 0-5% Methyl isobutyl ketone.

 

Backpackers use it:
"Zen and the Art of the Alcohol Stove"

 

The CDC reports NIOSH and OSHA exposure limits for methanol of 400 ppm, ethanol of 1,000 ppm and isopropanol of 200 ppm.

 

Sterno has apparently moved away from denatured alcohol for their fuel products to a "Green" series,which is ethanol-based.
