You can reduce the sooting a lot if you add 10-15% water to the metho :)

I suspect that it may reduce efficiency at any %, someone with a scientific outlook could test boiling times with & without....
....but I was just addressing the question of how to reduce sooting.
Personally - I let it soot :D
...... yet another noun has become an instant verb ! (goodness me - we do bugger up the english language)
Yes, happened about 1,100 years ago :D

But in my experience ,you get old waiting for a Trangia to heat a (Trangia )kettle for a cup of tea.
I ended up putting a Primus burner in the bottom, which was made for Trangias. It clips in the metho hole, and has a flexible hose that screws onto a squat type cartridge.
Don't use it all now as SWMBO dislikes anything Trangia, and will not cook with them, so if I want dinner it had to go.
Now we have the camper trailer which is "pre shmick" so has two of those cast iron burners which do a great job.
We also recently bought the latest tech Companion silicone fold down kettle which is great because it has a really wide base and heats water about twice as fast as the Trangia kettle and takes up very little more space.
We also have a ABR Sidewinder rectangular pan which fits great on the limited size stove and cooks bacon and eggs well.

Ethanol is miscible with water in all proportions - ie it's not like putting sugar in your coffee, where it will dissolve a few spoonfulls and then clump up on the bottom of the cup. You can add a drop of water to a litre of ethanol, or a litre of ethanol to a drop of water, and it will mix at a molecular level.
As to how much water you can add to metho (ethanol) and still be able to light it, I'm not scientifically sure. But what I do know that Bacardi 151 proof rum has a flammable liquid warning on the back :eek: That is approx 75% alcohol by volume
We found the wind and temperature conditions affected the use of the Trangia. During winter we found we would use more than twice the amount of fuel than we would in summer to do the same thing. Same with the wind getting the Trangia sheltered did a lot too improve its effectiveness.
Overall we never found it to be that slow. On the other hand, we did try using a butane burner once to make 2-minute noodles. An hour later we were still waiting. When we got back to the caravan park we left it in the camp kitchen for someone else to use.
Gotta agree with teh camper trailer now. Camping is so easy with it.
Just a little post at the end
My Origo metho stove is the type used on boats so is well sealed when not in use Safe to use in confined spaces doesn't generate nasty gases.
I only use it in the camper for brekky or other meals when weather is foul or a late cuppa And metho is readily available I small quantities for these situations

On another camping topic, muddy ground. You know how its a problem when the ground gets muddy when you've been camped in the same place for a while.
The best solutions include a roll of rubber sheeting with holes in it, or those square rubber mats which clip together. My son found 20 of them chucked out on the roadside in a street cleanup.
Or, if you're a cheapskate like me, go to your local second hand junk shop and buy some old carpet squares for $1-2 each. Yes, the carpet will get filthy, but so what? Just chuck it on the ground when you get home, hose it down and leave it to dry out.
Beats walking around in mud and certainly improves the camping experience.
