I saw a few alcohol stoves where they put fiberglass insulation inside the stove. I was wondering if anyone noticed a difference. The only upside I can see to this is in case it tips over alcohol wont spill. But does it affect boiling times, heat output, or burn time?

I see Tinny's Bongo has a "wick" similar for reference. Just wondering your opinions/facts on this matter. I am in the midst of building an atomic(s) and experimenting with hole sizes, amount of holes, and perhaps the stuffing wick idea. Thanks for any feedback!
