But you didn't add any Hexamine?

HEXAMETHYLENETETRAMINE (HEXAMINE) is a white crystalline powder with slight amine odor. Specific gravity is 1.27 at 25C . HEXAMINE is soluble in water, alcohol, and chloroform, but insoluble in ether. Formaldehyde and ammonia yield methenamine, or hexamethylenetetramine, which is used as a urinary antiseptic. Nitration of methenamine gives the explosive cyclonite, or RDX. Formaldehyde and acetaldehyde react with Hexamine in the presence of calcium hydroxide to give pentaerythritol, the tetranitrate of which is the explosive PETN. HEXAMINE is also useful in adhesives, coatings, and sealing compounds. In medicine, it is an antibacterial agent. It is used as a dye fixative and in the preservation of hides. It is used in vulcanizing rubber and as an anti-corrosive agent in steel. It is used in the detection of metals and in the absorption of poisonous gases. It stabilizes lubricating and insulating oils. It is sometimes burned in camping stoves, because it burns without smoke.

yup...you just made mini-candles...drop-scone style...nom nom nom

 

[FreddyFish]

so how do they burn?

 

[John Fenna]

I use old candles melted down and poured into egg-box moulds full of sawdust from my firewood cutting plus dust from my beltsander - no waste - no cost.
Tese burn realy well and I often use them in my Hobo ...the downside is the huge amount of greasy soot that they leave on the pans

 

[bigandy]

i would nt have used hexi blocks to make them though!probably cost as much to make as you will save!!

 

[WeThePeoplexfbm]

i hate esbit blocks they dont burn as hot as the red ones ^^

 

[spiritwalker]

still think the clas olsen pine blocks at £2.99 per pack of 72 work out the cheapest each one burns for approx 10 mins bit sooty but all natural

I still don't get it :-( how do the melted candles replace hexi blocks?

 

[spiritwalker]

the coated cotton balls burn like a fuel

 

[Dartmoor navigator]

Sorry, I missed the cotton ball bit - I'll get back in my corner :-D

 

[WeThePeoplexfbm]

i dotn think they are in aussi but i sometime use fire lighters and they work fine but not the best ^^

Any idea how long it takes to boil water compared to hexi? I realise you've run out of hexi so a comparison might be a bit tricky but you'll know roughly how long it took with hexi I'd imagine? I've never tried this and I'm curious how long a cotton ball adds to burn time in wax and what the heat output is like...

around 8 mins for a canteen cup

they burn 1 around 13 mins? i think and they burn pretty hot, just around hard to light
