Is there not a problem boiling water in an endangered mug? Not sure I'd want to. Mind you I've got so many light pots to suit many different stoves I'm spoilt for choice.I prefer Vargo Ti-Lite 750ml Ti mug/pot, an alpkit 450no Ti cup and the AGG alu 3 cup pot for the wide burners like white box stove. These pots weigh 97g for the alu AGG pot then 110 g for the Vargo pot. Not sure about the alpkit one but it's not enough capacity for me so only used if I want a second pot for making coffee then having the bigger ones for boiling water for dehydrated food. I usually have double portions because I need a lot of food each day.Fuel is the big weight too. For my use I typically get at least 5 days from a 100g gas can. I've had as much as 7 days once (brews morning, lunch, evening meal and last thing at night. Then noodles at lunch, dehydrated food in the evening and usually porridge for breakfast.) All that and it lasted 6/7 days! Makes a good use of the.gas I reckon and goes some way to negating the weight of the can. Meths is relatively heavy for calorific value but through experience you can burn it very efficiently to make the most.of the energy being carried as meths.
