Hello folks,
I’m not sure if it’s a symptom of being an engineer that has guided me down this route or the fact I’m a geek! :shock:
I wasn’t happy using Tea Light candles surrounded by my wood turnings without understanding what temperatures I was actually exposing the wood to. (Discussed in a previous thread on here)
So with the loan of a piece of lab kit from work, I thermo-coupled my new creation in 4 different places to give an overview of what the temperatures were. At the same time it’s answered exactly how long they actually burn for. (Not that it’s particularly interesting!)
The pictures show the placement of the sensors.
Channel 1 - Bottom
Channel 2 - Top metal lip
Channel 3 - Side
Channel 4- Top wood edge.
(I think this is a reasonable spread)
The graph shows the temperatures recorded for a full candle… Which burned for Just under 3.5 Hours. A lot longer than I expected.
I feel comfortable that the wood isn’t exposed to severe temperature but it is higher than I expected.
Like all candles I’m going to advise anyone I give one, to ensure they are not left unattended.
The bottom sensor peaked at just over 85 Deg C.
Experiment over…. I really do need to get out more….. :roll:
Cheers
Shaun
