Wax adhesion

[txwelder]

I am using Cargill C-1 (80% soy and 20% palm) in a 8oz Clear Metro jar from the Jar Store. I am having trouble with the wax adhering to the jar. Some parts are fine and others are terrible. I am pouring the wax at 115 degrees with a room temperature of about 73 degrees and 55% humidity. We own a candle company and this is a new project for a wholesale customer so this is the first time I have poured this wax in these containers. We do a 2oz tin for them and since you can't see the side of the tin, adhesion has not been an issue. I pour the candles in what I call "rounds". Five-3lb pitchers at a time, this will do about 42 to 43 containers. I have seen that preheating the jars is one recommendation but I am not sure how to get that many jars preheated and keep them warm until the wax is at pouring temperature.

Any suggestions would be greatly appreciated.

I don't make as many candles as you but what I do is I place my jars on a cookie sheet and turn the oven on low. When it hits the low temp, I turn off the oven and place my jars in the oven for a bit. I take them out to get them back down to a cooler temp but not too cool.

One other thing I do, that I didn't see you mention, is place them in the dishwasher and wash them all before using. I store them back in the box upside down so as not to get dust or hairs in them.

Thank you for the quick response.

Yes we do wash all the jars before pouring. Guess I will give that a try and maybe use a heat gun to try and maintain temp until wax is ready.

Thanks Again

C-3 is better for jar adhesion...give that a shot. That's we use...we have some trouble with wet spots in our tumblers, but we pour at about 150F or below. We wash out the jars with an ammonia based glass cleaner, and don't preheat them. Good luck.

Unfortunately I can't change waxes. Our customer has requested the C-1 because they have had these candles for sometime and do not want to change waxes.

I will try the cleaner though.

Thanks

I use heat lamps to keep my jars warm. I got mine at Menards for I think $7 each plus the heat bulbs. I hung them over my pouring table using a bit of light weight chain that I had around with a hook in the ceiling that way I could adjust the height depending on the room temperature. I have all three plugged into a power strip that way I can turn them all off and on and not have to deal with unplugging them to turn them off (they don't have switches) and I only had to run one extension cord instead of three.

HTH!
