A Caldera cone fitted for the Trangia 28 series pot and lid.
Two cups of water at a good boil in about 6 minutes in perfect conditions....my garage.
The cone has a tendency to stick to the pot.
An alternate setup with a teapot, using the Trangia burner and support (not shown).
The cone has to be lifted to access the teapot.
The Trangia burner lights easier and can be snuffed, but the 12-10 is much lighter. Both stoves could boil 2 cups on 20mL but not 15mL. The Trangia burns hot and quick, the 12-10 cooler and longer. All this was done in a cold garage with no wind. According to the maker, the sticking issue will resolve itself as it breaks in. I'm not so sure about that, every time I unrolled it from storage the sticking was happening.
