Add water to a large pot (just a few inches of water is fine). Then, turn on the stove to medium heat.
Next, pour soy wax flakes into the pouring pot and then place the pouring pot into the larger pot of water - double boiler style.
As the wax starts melting, stir it with a wooden spoon.
Stir every so often until all the flakes have melted completely and the melted wax is transparent.*Once the wax is transparent, you can add color if desired. I didn't add color to mine, so I didn't include it in the steps. But I did explain exactly how you can add color below in the 'how to add color to soy candles' section right below the steps.
Remove from heat and let the wax cool for 5-10 minutes. The ideal temperature is 130-140, if you have a candy thermometer available to check the temperature.
Now, if you want to make your candle scented, pour in the scent you'd like to use and stir. But again, make sure the wax has been removed from the heat before adding scent because otherwise, the scent may evaporate form the wax.I used essential oils, but you can also use fragrance oils (which you will not need as much of to produce a noticeable scent).Need a starting point? 15 drops of fragrance oil or 20 drops of essential oil is a good start to make one scented small to medium size candle. But a more precise rule of thumb for fragrance is one ounce for every pound of wax.FYI - It will smell more potent in melted wax than it will in your completed burning candle. While you are waiting for the wax to cool, add a wick and metal tab to each container. If necessary, assemble the two pieces, but the ones I have linked come pre-assembled to make it easy!I like to dip a tiny bit of melted wax onto the metal tab and then place it in the center of the container. The melted wax hold it in place, so it will stand up on its own.You can also use a dab of hot glue instead of the melted wax, if you prefer. Or as another option, some candle wick kits (like this one) come with little stickers for the tabs that you can use to attach them to the container. Next, pour the wax into each container, avoiding the wick if possible. And wait for the wax to set up completely (12-24 hours) before moving or handling at all. I usually let my candles set up overnight.As the wax starts to set, it will get less and less transparent, until it's fully opaque.
Once fully hardened / set, it's almost ready to use. First, you have to trim the wick down to 1/4 inch. You'll want to continue to trim it to this length every time you light it for safety and even burning.
