Interesting. Points out the need to study more about high heat vs
low heat cooking.<br>
<br>
Large pots with large tops can lose much more heat than small pots
with small tops (especially when there is no lid). <br>

<p class="MsoNormal">It shows something unusual about a stove
cooking with two different pots (not at the same time). The
thermal efficiency is almost always better for a large pot
than a smaller one, but this is not always the case. Assume
nothing.<o:p></o:p></p>

<p class="MsoNormal">The thermal efficiency of the small pot was
higher on low power than the large one, and the reverse was
true at higher power. Low power flames can be very unstable to
don’t read too much into this, other than make no assumptions
– test the combination (stove+fuel+pot) to find out what the
performance actually is.<o:p></o:p></p>
