It's a miniature "wash bucket" (apparently for doll houses) made by a company called Mayberry Street Miniatures ($1.99). It has a larger capacity than the tea light stove and I wondered if the flame pattern would be as focused.
After some experimentation, I found that it produces a nice, steady flame that focuses directly on the bottom of the pot similar to the tea light stove:
In a kitchen test, I got the following results:
Time to Boil: 7:19 min.
Total Burn Time: 13:24 min.
Weight: 0.3 oz.
Capacity: 1 fl. oz. (approx.)
Elevation: 5,300 ft.
Here is a size comparison (from left to right: regular tea light stove, Wash Bucket Stove, 1 oz. tea light stove, wedding tin stove):
I just thought those searching for a higher-capacity alternative to the tea light stove might want to try this out. For those interested, it's item #661405. I suppose I could remove the the little rings on each side that are supposed to be handles but it kind of adds a bit of charm.
