lightmyfire Posted November 17, 2018 Share Posted November 17, 2018 I was on a crafting site a few weeks ago (I cannot for the life of me remember what it was) and I was searching for information about sink holes and how to avoid them. I've been making candles for about 4 years so I'm getting the hang of this and I'm always reading threads here- I've learned a lot over the years about pouring temps, etc. Now this may be something ya'll already know, but the tip I read that has changed my life is that if you are using a jar that changes shape at the top, stop your pour before you get to that narrowing. I have added 8 oz square masons to my lineup just for seasonal scents (I only use 9 and 16 oz amber straight sided jars--keeps my life as simple as possible!) and I was read to pull my hair out due to sink holes on every candle, every pour. It was driving me insane. After I read the tip I mentioned, I stopped pouring right where the flared square part of the jar narrows to the neck. Voila. No more sink holes. I can tell when I've poured just a bit too far because I will get a sink hole; easy to fix with the heat gun as soon as I see it. It sure beats fixing every dang one of them. 5 1 Quote Link to comment Share on other sites More sharing options...
thehappygoat Posted November 18, 2018 Share Posted November 18, 2018 Thanks for sharing, lightmyfire. I didnt know that, but I will try it with my next candle. Quote Link to comment Share on other sites More sharing options...
TallTayl Posted November 18, 2018 Share Posted November 18, 2018 I dunno about that. Soy wax can be a finicky mistress. Poke around under the surface of your next bunch of candles and see if it holds true, ive had sink holes/cavities in many containers at different pour levels. The only way they stay at bay in my shop is by managing pour temps and rate of cooling. Quote Link to comment Share on other sites More sharing options...

Well I do manage them with pour temps and as for rate of cooling I wrap each candle in a felt wrap to slow the cooling. I still do that. I do all of that, believe me. But as an added precaution I don't pour past the narrowing of the jar. It's just another step. 1 Quote Link to comment Share on other sites More sharing options...
moonshine Posted November 18, 2018 Share Posted November 18, 2018 Very interesting as I use the square masons and with 444 I still get sink holes and giant cavities filling just to level before the neck and it happens at various pour temps and cooling rates A few I thought were perfect I poked just to be sure thinking I hit the golden ticket on temps and down both sides of the wick I had complete air all the way down 🤷♀️ Quote Link to comment Share on other sites More sharing options...
lightmyfire Posted November 18, 2018 Author Share Posted November 18, 2018 my tip wasn't intended to be a panacea, merely a suggestion on something to add to your considerations when pouring a candle in a jar with a neck that's narrower than the jar. That's all. 3 Quote Link to comment Share on other sites More sharing options...
moonshine Posted November 18, 2018 Share Posted November 18, 2018 I appreciate that I really do I’m just puzzled why it hasn’t worked for me 😂 Quote Link to comment Share on other sites More sharing options...

I just poured 6 of the 9 oz straight sided amber jars and as a test I poured at 160 instead of 155 and I went past the point where the neck narrows and I have sink holes on every candle. The combo of lower temp and fill point just seem to be a happy combo in my studio. 2 Quote Link to comment Share on other sites More sharing options...
Laura C Posted November 18, 2018 Share Posted November 18, 2018 I wonder if the altitude or elevation one is in makes a difference? Not only with the air pockets and sink holes but with everything; scent throw, wicking, jar adhesion, etc.? 2 Quote Link to comment Share on other sites More sharing options...

I would think it would be like baking.......I had to adjust every cake recipe for the altitude when I lived in Denver. Not so much in Texas But at some point I guess I realized that this craft is what it is...........I think sometimes there's just no explanation. I have strengthened my intestinal fortitude immensely. 2 Quote Link to comment Share on other sites More sharing options...
