My candles are cracking

Please help.

I have started making votive candles and they are doing two things one is they are cracking across the top and the second is that there is a small cavity near the wick.

Does anyone have a solution?????

Thanks

Hi,

Thanks for your email and your post here! Wax has a tendency to shrink when it cools. The temperature of the wax when it is poured into the mold directly affects how much the wax will shrink. The greater the temperature difference between the temp of the wax and room temp, the greater the shrinkage. You might try pouring at a little cooler temp.

Cracking usually happens when wax (especially soy wax!!) is introduced to a rapid temperature change. When you pour your votives, are you putting them directly in the fridge or freezer? If so,... how long are you keeping the votives in the fridge/freezer?

Try to minimize the amount of time your candles sit in the extreme cold... once they harden up at room temperature, it's hard for them to shrink any more. Maybe 5-10 minutes... just enough so you can pop them out of the mold.

Thanks!!

Will R.

Thank you for your response. We are not putting the candles in the fridge/freezer. We have the votive molds on a cookie sheet and leaving them on the counter. We live in Texas so we do have the AC going would that have an effect on the candles? We have tried pouring at a lower temp but we still do have cracks but they are not as deep. At this point we are calling them character cracks. We will keep trying different temps until we get the right temp for our area.

Thanks

Hi,

Here is the info for the wax you mention:

Heat wax in a double-boiler system to 160°F - 180°F. Add fragrance and dye, stir thoroughly.
Make sure molds are at or above room temperature before pouring molten wax into them. This helps to ensure that the candles will release properly.
Lower pouring temperature to between 140°F - 160°F.
Allow to cool. You may place in a water bath or refrigerator to accelerate the cooling process.
Different wicks may be needed depending on dye/fragrance combination. The CD & ECO wick lines have been found to work well.

If you are following these guidelines, you may try contacting lonestarcandlesupply.com for additional information. I have never worked with this wax... but I have gotten bad batches in the past. If you have the box, there should be a lot number. You might see if it has been recalled or if there is other information you should know about this wax. Sorry I couldn't be more help!!

Re: My candles are cracking

Hi- I was having the same problem.. This is what I started to do and it has helped. I added st. acid as well as a mold release. I also pour 1/2 then 1/2 then top them off. It's a process but it's less aggrivating than waiting for your beautiful candles to crack. I feel your frustration. A lot of candle makers have the same problem with this votive soy wax including me! Try that and see.
