Congrats on your first batch! I have 3 prestos and also use C3 wax..it melts on 200* in minutes. I never actually timed it but I love my Presto's! I see you had a little frost on top of the candle..if you have a heat gun you can zap the top and it should go away..I will give you an overrun of what I do..just to give you an idea... I add the wax to my presto..let it melt..I prepare my jars which I set on a tea towel so the heat will distribute evenly, and our house is always 73-75*, once the wax is melted I pour what I need into my pouring pot , I usually don't add dye..but lately ppl want colored candles so I use blocks..I have found that liquid makes C3 frost horrible! The blocks don't,or haven't for me anyhow...then I add fo and stir,stir,stir usually a couple of minutes..then pour into jars,no, I don't pre-heat my jars. I usually get perfect tops..no frost or holes.I try to pour as hot as I can it works for me. Also I do temper my wax..Stella has this down pat, if you do a search it will help alot..especially with C3..but I would imagine this technique will work w/ any wax.(soy) May I ask what kind and size wick you used for that jar? I think it looks beautiful..just think how many candles you will put out with a couple Presto's! Good Luck.. Kim
