    Did the two vessels have the exact same geometry? That can make a huge difference, regardless of the metal. Exact same burner too, right? And ambient temperature, wind etc.?

    Buck up... my calc III was easier than the 2nd semester. Differential equations did whup me pretty good though.

    Yes they were very close in geometry, the burner was not changed, on pot was off and the other was put on. The 40 LB tank was almost full. It was the SS pot first and the AL second. I measured from 100F to 200F to take any initial differences out, and deciding when it was boiling out. Not what I expected at all. From some calculations of overall heat transfer I thought the AL would come to temp faster, maybe about 30 seconds. It was slower.

    Interesting. I feel like pulling out some cookware and playing around. This could make a good geeky Zymurgy article.

    Yes, a Zymurgy article has come to mind.

    Ah, Calc III. Definitely my favorite freshman-year class. I remember it well. Well, maybe not so well as that was 36 years ago. Still, who doesn't like Green's theorem?

    Green's and Stoke's theorems aren't for about 7-8 more weeks. Lucky for me I've taken linear algebra, or cal III would be much more of a bitch.
