Most wax averages to about 86% the density of water. The slight differences still matters. Instead of melting the same g of wax based from the water. I use water weight * 0.86 and thats the g for my wax. water weight 260 g x 0.86 = 224 grams of wax. works all the time
I can def add that to the list! In the meantime, this might help. You can combine different fragrances to make a custom blend, you'll just want to make sure you don't sure more than the wax's max fragrance load. Many waxes can hold up to 10% fragrance load so I'll use that as an example. If you have an 8 oz candle with a wax that holds 10% fragrance, you could use 0.8 oz of fragrance oil in total. 8 (the oz of wax the candle holds) x .10 (the fragrance % as a decimal) = 0.8 oz (the weighed oz of fragrance load to use) If you wanted to use two scents in a 50/50 blend, you could divide 0.8 by 2 to get 0.4 and 0.4. You would use 0.4 oz of one scent and 0.4 oz of the other. For other blend ratios like 75/25 for example, it would look like this: .8 oz x .75 = .6 oz of fragrance oil for one scent .8 oz x .25 = .2 oz of fragrance oil for the other scent Together, that still gives you the .8 oz of fragrance oil for the 10% load for that 8 oz candle.
@@candlescience great! I am trying to make a cheat sheet of sorts with like min and max loads. I had a sheet from you guys with the burns, but lost it when I moved everything. Can you send me a copy of the sheet again? Love to add a min/max area for fragrance loading and have some room to work as well. Maye, even do one for 3 fragrances. Thanks for all you guys do, your the BEST!!
We'd still recommend weighing your oils on a scale, just make sure to not use more than the recommended amount for the wax you'll be using. Let's say you'll be using a total of 1 oz of fragrance oil for your candle. If you want a 50/50 blend of 2 scents you would measure out 0.5 oz of one scent and 0.5 oz of the other.
When measuring in fl ounces you would be able to use something like a measuring cup or graduated cylinder to measure the melted liquid wax. We always recommend measuring by weight and not volume for candle making though. To measure by weight you will need a scale that reads in weighed ounces or grams. Be sure that the scale is "tared" or reads 0 before measuring out your wax. Place a container on your scale and set it to 0. Then as you pour wax into the container, the numbers displayed with be the wax weight.
To calculate a higher fragrance load, you can multiply your total amount of wax by the fragrance % you would like to use. To calculate a 9% fragrance load, for example, would look like this: (oz of wax using) x (0.09) = (oz of fragrance oil needed)
Because we cannot know the fragrance load a maker will use, we list the wax weight as the amount of wax that will comfortably fit inside the jar. This also works for unscented candles. Using higher fragrance loads, there may be a bit of wax and scent combination left over using this formula, which can help if there are uneven fills, spills, or surface flaws that require a second pour. If you would like to calculate the exact amount of fragrance and wax needed for a batch of candles you absolutely can! The formula is just a bit more complicated and does not leave any room for error.
You sell candle supplies! How can Candle "Science" get math wrong? Firstly, candle jars have a fill to line. A supplier knows that right? Its listed in the description of the jars! I keep posting the correct formula and information but they delete it. Just thought i would vent. Thx for listening to my Ted Talk.
Straight to the point 🥲 and very helpful ✨
Always happy to help!
Thank you so much for this!
Always happy to help!
Thank you for sharing! This will be my guide for starting scented candle making later. Godbless😊
Very happy to help! If any questions pop up, just let us know!

water weight 260 g x 0.86 = 224 grams of wax. works all the time
This would also be a technique to try, it should be pretty accurate!
Very helpful
Thank you
Always happy to help!
Could you do one that shows when using more than one fragrance
I can def add that to the list! In the meantime, this might help. You can combine different fragrances to make a custom blend, you'll just want to make sure you don't sure more than the wax's max fragrance load. Many waxes can hold up to 10% fragrance load so I'll use that as an example.

When you’re mixing fragrance oils how do you weigh them?
We'd still recommend weighing your oils on a scale, just make sure to not use more than the recommended amount for the wax you'll be using. Let's say you'll be using a total of 1 oz of fragrance oil for your candle. If you want a 50/50 blend of 2 scents you would measure out 0.5 oz of one scent and 0.5 oz of the other.
So is it 8 oz of wax plus the amt of oil? Or wax + oil to = 8oz????
How to measure wax in oz or fluid oz
When measuring in fl ounces you would be able to use something like a measuring cup or graduated cylinder to measure the melted liquid wax. We always recommend measuring by weight and not volume for candle making though. To measure by weight you will need a scale that reads in weighed ounces or grams. Be sure that the scale is "tared" or reads 0 before measuring out your wax. Place a container on your scale and set it to 0. Then as you pour wax into the container, the numbers displayed with be the wax weight.
A scale
Hello from Portugal. How many Fragance Oils, for candles do you have?
Hi! We have 211 fragrance oils for candles but we are currently only able to ship within the US and Canada.
When you have 1ounce bottles of fragrance oil and you want to use more than 6% how do you calculate that?
To calculate a higher fragrance load, you can multiply your total amount of wax by the fragrance % you would like to use. To calculate a 9% fragrance load, for example, would look like this:
(oz of wax using) x (0.09) = (oz of fragrance oil needed)
Candle fill line = wax PLUS fragrance oil. The wax weight is NOT the fill line. This formula doesn't work.
Because we cannot know the fragrance load a maker will use, we list the wax weight as the amount of wax that will comfortably fit inside the jar. This also works for unscented candles. Using higher fragrance loads, there may be a bit of wax and scent combination left over using this formula, which can help if there are uneven fills, spills, or surface flaws that require a second pour. If you would like to calculate the exact amount of fragrance and wax needed for a batch of candles you absolutely can! The formula is just a bit more complicated and does not leave any room for error.
I agree!!! I get 30.16 wax and 1.84 fragrance oil.

Not everyone uses containers with fill to lines. I use upcycled containers so they don’t have those lines.
You’re wrong 🙄🙄🙄
Thank you, Dana, you can never stop learning. This business is like therapy, ongoing! 🫶🏽
We're always looking to learn something new over here as well!
