I spent part of last weekend with my friends whom I have known since my early 20s. I am 39 years old. They allow me to be goofy and silly and awkward and say whatever comes to my mind. Being in their presence brings me joy.
Each candle usually burns for about 50 hours. After that, all you need to do is pop the porcelain bowl into your freezer overnight. The next day, take out the bowl and the wax should be hardened. You can then pop out the charged crystals. Then the wax should pop out easily too.
Back in October of 2018, I went over to the house of a family friend who kindly taught me and a bunch of her friends how she makes candles. I highly suggest finding someone like this who will give you a hands on tutorial and step by step process. I learn best when I see it actually happening, and I actually do it.
