Education is not the filling of a pail, but the lighting of a fire. W. B. Yeats
Its all just smoke and mirrors
Our deepest fear is not that we are inadequate. Our deepest fear is that we are powerful beyond measure. It is our light, not our darkness that most frightens us. We ask ourself, who am I to be brilliant, gorgeous and talented? Who are you NOT to be?

Let's turn those old bridges we crossed into ashes.
We'll blaze a new trail,
and torch the rough patches.

quote:Actually, my wicks smoke more the warmer they get. After 5 burns they smoke loads more when they go out than after 1.
you may notice that when your wick goes out it smokes less with time this is why, as with time it is only the fuel that is burning
quote:yes as long as you blow it out before the fire gets to small (some ppl smother rather than blowing it out)
So ben-ja-men, does this mean that you can get the same effect as curing by simply ensuring prompt dipping on your first few burns.
quote:its like in maths where you get taught in bits that are relevant to your particular stage whereas later on not all of the steps are necessary, like in high school they teach you that calculus is about finding the area under a curve, then at university the first thing they tell you is to forget everything they taught you at high school.
I ask this because I have usually seen 'curing' presented as being some special process with specific advice as to lighting for just a few seconds, and not spinning the poi during the curing process.
quote:yes as a good practise i would say for all burns just to stop any smokeyness
Whereas (correct me if I'm wrong) you're saying that the same effect is achieved by the prompt dipping of wicks after the first few burns (which I completely agree with)
quote:yes ive found plastic melts when it comes in contact with kero though
If your entire wick is soaked well, before a burn and dunked soon after a burn, its all good. Wicks should be kept moist whenever possible to prolong their life. I keep my wicks wrapped in plastic so they are airtight.
quote:i was actually refering to as weeks and months pass, i think you are refering to when you redunk in the kero rather than the smoke coming off the wick itself when it goes out
Actually, my wicks smoke more the warmer they get. After 5 burns they smoke loads more when they go out than after 1.
quote:as far as money goes yes, for me my staff is my staff and its special to me i find i develope a familiarity with it over time and slight differences occur from staff to staff i like my staff to last as long as possible to stop from going through that rediscovery process maybe thats just me though
Charles was much more on the ball with the fuel comment, we spend a shed load more on fuel than kevlar over the year but the only talk of being economical with fuel is on this thread There are even a couple of little vids.
quote:to cure means to perserve a product so i think its kinda an applicable name
This word 'cure'. Its not curing anything, just soaking and burning.

quote:650 K is only 380 °C
You say when you stick the kevlar in a fire uncured the kevlar itself burns...How hot is this fire?
I know the wick here at HomeofPoi will resist degradation until it reaches at least 650 degrees F. The kevlar in the wick wouldn't burn at all.
quote:https://www.homeofpoi.com/fuel.htm
Extinguishing equipment:
Blow out fire from the bottom of the wicking. If they don't go out after two blows place them on the ground and smother them with a damp towel. (Do not smother with a damp towel if that gear needs to be reused later in the performance. In an emergency, USE A FIRE EXTINGUISHER
Do not let the kevlar wick smolder, as it will not last as long

quote:Ah, I'll have to disagree with you there - College chemistry has told me otherwise. The hottest part of the flame is what's called the C sector. Here's a crappy drawing:
this is for a candle, bearing in mind that the wick is in contact with the hotest part of the flame all the way through the burn. So the bigger your wick the hotter the temperature ....
code:Consider this is 2 dimensional, and in three dimensions, A would be right at the surface of your poi, whereas C would be suspended quite a bit farther away from the heat source, or fuel/kevlar. Try it: Melt something right at the surface of the flame, and melt it 2/3 of the way up the flame, and it will melt SIGNIFICANTLY faster 2/3 of the way up.

quote:i get that the c spot is further away from the surface but wouldnt the overall temperature of all the points in the flame be hotter?
The larger the flame the COOLER the surface of the kevlar, as point C is a further distance away from the surface.
quote:if thats true Charles then wouldnt the cotton burn away faster if the surface of the kevlar had not been oxidised ie burnt?
It is the cotton first of all that smoulders/burns

quote:Although the overall energy expensed is greater, as more excited atoms (fire) are moving, the temperature in any given point on the wick (excuse the lack of proper vernacular) is lower, only because of increased distance between the kevlar and point C. It's true that if you harnessed the energy released through the flame it would be a larger amount than having a smaller flame, temperature per area would remain similar.
