For the test I chopped a esbit tablet in half as the tray is slightly smaller than this and put 500ml in the Snow Peak 600. I didn’t bother to time the exercise nor weigh the chunk of esbit. The test was carried out indoors in a well ventilated room with a windshield in place.
The fuel got the water to a good boil with some to spare. There was spillage of the flame up the side of the pot. This was due to the pot’s diameter and, perhaps, the size of the chunk of esbit used. Cutting the tablets in quarters and stacking two on top of each other should help concentrate the flame under smaller diameter pots.
The next step is a quick test to ascertain the fuel efficiency, speed of boil and to see whether it integrates with my Bush Buddy.
Doing this quick test reminded me why I used my old army solid fuel cooker; it’s simple and effective. But as with all stoves it’s not without it’s downsides with the fumes and blackening of the pots.
