How to Make a Black Candle

The hard part of making a black candle is figuring out how much candle dye to use to get truly black candle wax. It’s a Goldilocks problem – use too little and you get a grey candle. Use too much and you get a black candle that doesn’t burn well (because excess dye can clog the wick). Here’s how to get it just right:

What You Need to Make a Black Candle

To make a black candle, you will need:

1. Candle Wax – I’m using a blend of paraffin and soy. Paraffin takes color better than soy wax so I would avoid trying to make a black candle with 100% soy wax. I’m using 70% paraffin and 30% soy.
2. Candle Wick – Plus a wick sticker and a wick bar to center it.
3. Liquid Candle Dye – You should use liquid candle dye, not dye chips. With dye chips, your candle will probably come out looking more grey than black.
4. Stearic Acid – In most of my tutorials, I say that stearic acid is optional. For a black candle (or any other intense color), don’t skip it! It helps to improve the opacity of whatever color you’re trying to achieve. I recommend using 10% of the wax weight – e.g. if you are using 6 ounces of candle wax, use 0.6 ounces of stearic acid.
5. A Piece of White Paper – This is to test out the color before you pour. If you add even 1 drop of black dye to the melted wax, it’s going to look nice and dark in the melting pitcher. You’ll need to test it out on a sheet of paper to make sure that the candle wax is actually black before you pour.

Step-by-Step Guide to Making a Black Candle

STEP 1: Melt the wax. Add the wax and the stearic acid to the melting pitcher. Turn on the heat and melt until the wax reaches about 180 degrees Fahrenheit. This temperature may vary if you are using a different wax blend so check your wax’s packaging for the melting point.

STEP 2: Set up the candle container. While the wax is melting, wick the candle jar. I just added a sticker to the bottom of the wick, found the center, secured the wick in place, then centered it with a wick bar.

STEP 3: Dye the wax. The label on my liquid candle dye instructed me to use 7 drops per pound (16 ounces) of candle wax. Since I melted 13 ounces of wax, I knew that I would probably need between 4 and 6 drops. Start with less than you think you need and work your way up.

STEP 4: Test the color until you get black candle wax. I started with 4 drops of dye and then tested the color. You’ll never be able to judge the true color just by looking into the melting pitcher so take a drop of wax and put it on a white piece of paper. I’m using a dropper tool, but you can just dip a spatula in the wax and drip a little onto the paper. The wax dried to a slightly black color, but I wanted a more saturated color so I added 2 more drops. I tested the color again and was happy with the shade. Don’t go crazy with the dye. Too much dye will clog the wick and the candle won’t burn properly.

STEP 5: Pour the candle wax into the jar. After the wax cools to the correct pouring temperature, pour slowly into the candle jar. My pouring temperature was about 155 degrees Fahrenheit. This may vary based on the wax type you’re using. After you pour, all you have to do is wait!

STEP 6: After the candle cures, trim the wick and enjoy!

Top 4 Takeaways

1. Use paraffin wax or a paraffin wax blend. It takes color better than soy wax or beeswax.
2. Use stearic acid to boost the opacity.
3. Test the color on a piece of white paper before you pour.
4. Don’t over-do it. Too much dye will clog the wick.

I hope these tips help you to make a black candle that looks good and burns well.
