NaturallyTru Posted September 30, 2011 Share Posted September 30, 2011 Trying to help someone figure this out:She is in Jordan.She has some silicone rubber molds her mom gave her. She uses beeswax and beeswax/paraffin wax blend. She is getting fine white lines on her candles. She has poured at 70 celcius and 90 celcius. With the 90 the lines are less; but still there. I am thinking it is the cooling process. Any thoughts?Also she is saying that the mold is oily inside. She has tried washing a few times and even boiling to get the oil out; but to no success. Any idea what this may be? Can oils leach out of the molds? Any help appreciated.Trudi Quote Link to comment Share on other sites More sharing options...
Bernadette Posted October 1, 2011 Share Posted October 1, 2011 I'm hoping one of the professional moldmaker members will see this and respond. I'm a silicone mold user and have been for over 9 years. I have over 1000 silicone molds. Obviously, I don't use some for long periods of time, and when I do take them out to use, some are oily. I have molds from many, many makers, and my opinion would be that the type of silicone used is what causes some to be oily and others not. Some are so bad when I take them out that the only way I can carry them is to have one of my hands on the bottom; otherwise, they'd slip right out of my hands! Those are oily inside and out. I remove the excess by blotting with paper towels. They don't have to be bone dry of oil, and the small amount of oil that's left on hasn't done anything to the candles that come out. Pouring temps, which range depending on the effect wanted(i.e. mottled vs. regular) have never given me white lines. Now...there are some molds I have, touted as silicone that look like the concrete/ceramic molds you see. I'm sure they do have some kind of silicone in them, but something else has to be there because they are so heavy. These I have to clean extremely well, scrubbing with the green, no scratch side of a sponge, drying, and spraying with silicone spray right before pouring OR I will get lines. And I have to pour these quite hot. Can take days for these to set up, too, as they are very dense and hold between 8 ozs. to 10 lbs. of wax.

beekeeper_sd Posted October 1, 2011 Share Posted October 1, 2011 If your friend is pouring at 70 celius I think that is too cold. My pure beeswax is always kept at around 170 degrees F. I have also experienced lines when pouring in the winter and my shop is cooler. I now keep my shop temp. around 75-78 F year round. Quote Link to comment Share on other sites More sharing options...
