The video shows flames going up the pot sides which I feel (without a cone to conserve heat) is “wasting” heat. i.e. chimney needs to be taller, maybe by at least 1/4″. (IMHO)
To all true believers, Esbitmeisers and non-actualized Esbitmeiserettes, Merry Esbitmas!
I do believe in all things esbit related. Thank you Robert. I wish you good health and may your journey be long and inspired. Merry Esbitmas to you and to all a good night.
I was giving some thought to Frankinsense and Myrrh and came up with the idea to create an essential oil using esbit. It would have an apeal to certain ethnic groups that are associated with large amount of fish. It could be used in perfumery and aromatherapy. If it burned as well as solid esbit, it would be a dual purpose fuel

Whale/seal oil or blubber, as used by Eskimo and Antarctic expeditions.
Loving the regular thread drift in “Esbit Burner Testing”. Sorta like a walk around the borders of sanity – With Robert ad out guide. ;o)
Hope everyone had a Cool Yule.
Now have a very Happy New Year. And while you’re at it PLEASE invent a hotter ESBIT tablet.
I may have found an alternative solid fuel to heat(not boil) 1 cup of water/coffee. Product is in the mail and due to arrive Jan 3.

It’s called Government paperwork, especially everything to do with the ATO/IRS.
We burn it when it’s >7 years old – and there is a LOT of it.
Cheers
That’s putting it to good use :-)
The stuff I’m getting is charcoal impregnated with saltpeter/aka potasium nitrate. Suppose to be smokeless. Yes, I know what you are thinking ![]()
Hum … sprinkles flowers of sulphur around … :)
Cheers

Last stove for the year 2018. The Cuppa Tea Stove.
Solid fuel “Radical Charcoal” with Esbit assist.
 Charcoal burns so hot, the esbit has a hard time staying lit LOL I used esbit so I could include it in this thread

It will be paired up with an aluminum cup. It’s designed for those that live for a cuppa tea in the morning, noon and night

Looks about as useful as a chocolate fireguard.

Thank you Stormin! ![]()
Might it not be more cost-effective and fuel-effective to just use the lighter to heat the water directly?
Cheers
Yes….but, the esbit will be eliminated and so the charcoal is easily lit with a flick of a bic, a match or flint and steel sparks. I crammed the video in before the end of the year. The tea  teetotallers of the UK will love this new stoveÂ
 It’s work-in-process to get the specifics on length of burn, weight and time to boil 1 cup. It will probably heat 1 cup before you can even set up a canister stove ;-)
I nominate the Cuppa Tea stove for the best 2019 New Year’s Day stove! Oxyacetylene torch et al.!
Thank you Robert. I’ll send you the 1st production model 
The other day I got 3 of these to play with:

New sliding lid tin modified for esbit. Has the ability to simmer.
Weighs 8 grams. Has elongated slots on side for air entry for complete combustion.
That’s all folks.
Bravo!
Lab Tests!
How much smoke and soot?
It does look very clever.
Cheers
Lots of smoke, lots of soot. Better to use canister stoves. See Stovebench thread.
Dan,
In my opinion, long-term evolution of the sliding lidded Esbit tray might diverge into at least 3 variations: 1. Optimized for the 4 gm tabs; Â 2. Optimized for both tab sizes; and 3. Optimized for the 14 gm tabs.
2. Maybe then renamed the Esbitoptimiser?
Small holes on both long sides near each end to take wire stubs, so can be hung level in use.
esbit insert tray for Trangia 25 kits. 14 gram cube boils 500ml in 5.5 min.
