xxxAlpha71xxx Posted October 13, 2019 Share Posted October 13, 2019 Container candles heat up quite a bit as the wax gets lower and lower in the container. I've searched around and I can't find an answer to a simple question: How hot is too hot? Quote Link to comment Share on other sites More sharing options...
CandleRush Posted October 13, 2019 Share Posted October 13, 2019 There was a candle video posted somewhere here which addresses heat. I believe the temp should stay under 170. It may even be lower then that. You can use an Infrared thermometer to check. Right now I’m burning an 8 oz square jar over 5 hr. And it’s just warm, full melt pool 1/4 inch deep, lower half of jar when things really get heated. I could hold it non stop with no issues. My early Candle days, they were so hot I could not hold them much less move them to another location. Over wicking contributes to heat. Someone else will chime in I’m sure.🌸 1 Quote Link to comment Share on other sites More sharing options...
TallTayl Posted October 13, 2019 Share Posted October 13, 2019 @CandleRush is remembering correctly. The ASTM standards limit container temp to 170*F Quote Link to comment Share on other sites More sharing options...
CaptnKush Posted October 14, 2019 Share Posted October 14, 2019 I could have sworn that video of the guy testing said it was 140 degrees. 1 Quote Link to comment Share on other sites More sharing options...

Yes, there is a video on YouTube and it says 140*F for glass. The video is done by a man who tested candles for a living based on safety standards. 1 Quote Link to comment Share on other sites More sharing options...

xxxAlpha71xxx Posted October 14, 2019 Author Share Posted October 14, 2019 Thanks for the info all. I had a couple that I felt were getting warm but I don't think they were anywhere near 140 and certainly not near 170. I'd say they were equivalent to a very hot cup of coffee. Not hot enough that you couldn't hold them but hot enough that you certainly noticed it. I didn't have my temp gun with me and didn't think about it before I blew it out but I'll start checking them more closely. Quote Link to comment Share on other sites More sharing options...
