I always go back and reference your videos when I'm making wax melts/candles because even though there are a million videos/articles explaining how, you just explain it so clearly and easy to understand. It literally just makes sense lol.
Thanks for the info! I typically do wax weight * FO % and add to that wax, and use the leftover for 1 oz sample and a bit leftover in case I spill. But you do whatever works for your business model. :)
Oh if you add them together that’s actually the correct percentage! And if you don’t mind the extra to use for something else you can definitely do that ☺️
I am dizzy. I thought I had it but I don't. It's been 2 1/2 years trying to get wax and fragrance oil as well as type of wax and wick. I might quit but I have so many supplies. : (
2 different methods I've always used (UK based) 1) Fragrance Content - 220g candle (30cl) at 10% would be 198g wax and 22g FO 2) Fragrance Load - 220g candle (30cl) at 10% 200g wax and 20g FO. I always used to use fragrance laod until about 2 years ago. And then found out that fragrance content was the correct way as you say in the video too Lol In the UK we also have to apply a CLP label to the bottom of our candles (ingredients of the mixture with our address and phone number) and that clp label here is based on the fragrance content method. Thing is when starting out our research is generally from other makers which shouldn't be the case unless you then go fact check their advice, but i obviously didn't and was using the incorrect way for 2 years. Lol
I still don't get her formula. I calculate my candles just like you do on your 1) Fragrance Content method. Calculate % of the number I want of weight, then substract the FO grams from the total wax number to know how much wax per FO I need. But the more I look at her equations, the less I get them and everyone seems so happy with them. I feel dumb! I really have no clue!! I only know that by doing what I said, my candles work great and have had no problems so far.
@@JannaBanana so you take whatever vessel ypu have and find its fill weight. So my glasses hold 220g of total weight. And if i wanted 10% Fragrance content then i would work out whats 10% of 220 which = 22g so then i know my recipe is 198g wax and 22g FO then x that by the amount of candles i want x
Im France based and like you ive been using for years the same 2 fragrance load method too. One day I realise that people from groups arent agree with it and ive been told by three fragrance oils suppliers compagnies that it's incorrect and need to use the 1 fragrance content method instead. Thats what im currently doing and never had any issues. The issue now is to know which one is correct because as you said it can be a big CLP issue because of UFI. I dont know what to say about this because im confused now.
Took me few minutes but now Im getting what she is trying to say. She says that you have to calculate your FO percentage from your total wax weight and not the whole finished candle weight (wax plus FO no vessel).
A = Wax Weight X = FO% Wax Weight + (FO%)(Wax Weight) = Fill Weight OR (AKA) A + AX = Fill Weight Plugging in her example from the video… We want to know what the wax weight would be for a fill weight of 8 ounces and a FO of 10%… A + AX = Fill Weight A + A(10%) = 8 oz A + A(0.1) = 8 oz 1.1A = 8 oz A = 8oz/1.1 A = 7.27272727…oz Wax Weight is 7.27 oz (this is how much wax you will pour into the jar) Fill Weight - Wax Weight = FO Weight 8 oz - 7.27 oz = FO Weight 0.73 oz = FO Weight
I do fill weight e.g (220g) divided by the percentage of fragrance load I want. So if I wanted an 8% fragrance load, i would do: 220 Divided by 108%. That = 203.7. I then go back to my fill weight of 220 and take away the figure i just worked out, so 220 minus 203.7 = 16.3 So i now know i need 203.7g of wax and 16.3g of FO. If I wanted a 10% fragrance load = 220 / 110% = 200. then 220 - 200 = 20. So I need 200g wax and 20g FO 7% fragrance load = 220 / 107% =205.6 220 - 205.6 = 14.4 So i need 205.6g wax and 14.4g FO 12% fragrance = 220 / 112% = 196.4 220-196.4 = 23.6 So oi need 196.4 wax and 23.6 FO
Yes! That’s what I’ve been doing with the specific gravity (.86) and I never have leftover wax. I created a calculator in excel so now I just add the number of containers, the FL, the water fill weight per container, and it gives me the wax I need and FO.
Hi Chandler! Can you create the same excel sheet in “sheets?” I would definitely and happily purchase it from you! I am not even kidding! I am an older, but not wiser technically challenged chandler. Add disabled to that and I just need HELP!😅 I hope you see my reply soon! Thank you and have a beautiful day!
@@cbpapp Hi there! I am not familiar with "Sheets"? I did a bit of googling and it seems the format will work but the formulas may not transfer well. I can share it with you for free. I did make one in ounces but never tried it as I prefer grams for being a small more accurate unit of measure in my view. How would I be able to send it to you?
This is the same as bakers math. It's to make scaling easier, when knowing the weight of the flour and the desired hydration. Basically how much of something can hold, of something else, by its own weight. It's not a 'mathematically correct' way, but rather convention and wording. This is why there's text to be interpretated in school.
Yes! So you have to find out how much FO and wax you need for one candle and then multiply both those numbers by however many candles you want to make :)
From what Im understood in this video is when we tare trying to figure out the fill weight on the new cute vessel we can use water and use the formula to get the new fill weight. OK. So if I fill this new cute vessel with 10.5 oz of water I would then x it by 0.86 to get my new fill weight for wax. (10.5 oz of water x 0.86 = 9.03 oz of wax) correct ? So then ( 9.03 oz / by 110% = 8.2 of of WAX needed, Correct?) (9.03oz - 8.2oz = .83oz of FO needed correct?) Please correct me if Im wrong, thank you :)
OMG thank you for explaining this again! I see this so much in candle groups. It's not terribly hard. I found that with the common wrong way I was having so much left over wax and I wanted a more accurate number. Found a video that explained the different weights and then you candle math video.
Thank you Erica, for this and every single video you've shared💖 Also thank you for being your awesome you!!! I have learnt sooo much from you, and I can't thank you enough!!💗🥰💗
Need desperate help! I have done the exact formula but with grams rather than ounces and I have calculated the EXACT amount for 2 candles but when I started pouring I had enough left over for another candle. What did I do wrong?
Yep, I know that. I have an entire video showing how to find the fill weight by figuring out the difference in density between wax and water: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-uqA3wmabm5o.htmlsi=LkCqddw9K1WfIAhV Are you referring to the fact that I used color water as an example to visually show how my formula works?
I'm sorry but this is a mistake. Every formula should reach 100% which includes all the raw materials in it. To say that the fragrance is calculated from the wax, It's like saying that raw material X should be calculated in relation to raw material Z, this is a mistake. Fragrance is another raw material in the formula and it is calculated from the total (100%) product and not in relation to another raw material. It is true that candles usually only have 2 raw materials (wax and fragrance) but the calculation is the same. If I know that I want to make a 100 grams product, I refine each raw material in the formula in relation to these 100 grams. I mean, if I want 10% fragrance in the product it will be 10 grams, if I want 90% wax in the product it will be 90 grams, there is no other correct way to calculate it. Therefore the original formula is correct and not a mistake.
Actually fragrance percentages for waxes are the percentage against the wax, not the finished product. So if a wax manufacturer says max FO percentage is 10%, that is 10% of the wax weight, not your finished candle. Therefore your formula ends up with more than 10% of the wax weight and is incorrect.
Except in candle making, it IS in relation to the other raw material. Waxes have limits as to how much FO they can hold before it starts to seep/leak out. This is expressed as a percentage by the manufacturer. Surely you wouldn't advise a candle maker to create a candle that is 80% wax and 20% FO, just because it adds up to 100%, right?
@@ProducerEXL Exactly! If you exceed the manufacturers percentage limit of fragrance oil to wax you run the risk of your candle sweating fragrance oil once set. This can be a danger if it is excessive, as well as looking unprofessional. So while all your raw materials need to add up to 100% of the total product weight, you also need to make sure that your fragrance percentage is not more than the manufacturer’s recommendation for the wax.
Fill weight= 10 parts. 1 part fragrance and 9 parts wax. fill weight= 8oz. 8 devided by 10 = 0.8oz fragrance. the rest is either 0.8oz x 9 or simply 8 - 0.8 = 7.2oz
Ok I get it now. The visual helped because I didn’t realize the fill weight included both the wax and the FO. I’ve watched your past videos and just wasn’t tracking with you. But now I see a more precise way of measuring wax and FO and not being wasteful. Thanks so much!
Thank you. This made perfect sense. I’ve been doing it ALL wrong. Taking the FO% by total fill (ie: 8.15oz x 8% = Frag load …remaining wax) 😢 I’ve been using 5% too much and this explains my wicking issue. Thank you again and kiss the baby for us!😊
I am going to just try this because I am not good with numbers but your last formula helped so hopefully this will I am always open to learning in this candle world
Thank you for this and all your videos! It helped me a lot when I started my candle business ❤ Now I'm starting to make reed diffusers. Is it the same formula? Or the "incorrect" one for candle making? Thanks! 😘
Nice one. You got a lovely voice and nice way to explain things. I have made vanilla tealight candles using your formula and they have come excellent ✌
Hi Erica I watched all of your videos. First of all thank you so much for your sharing of your experience and your knowledge. I want to ask about the bees wax, why do you blend it to soy wax and which ratio?
I'm very new still researching and leaning. I've been using the candle calculator on Norden. So these candle calculators not give this result? Thank you for all your very helpful and informative content!
Math Explanation: Why the formula works From Erica's Example, we know that we have a fill weight of 8oz and we want a FO% of 10% So our completed candle is 8oz which is made up of X oz of wax and y OZ of FO. Wax + FO = 8oz Or x + y = 8 But we also know that we want FO% to be 10% of the wax weight or x So y = .10x So we can substitute that for y x + .10 x = 8 Or 1x + .10x = 8 (the 1 is implied above) Which we can simply to 1.1x = 8 (Add the x's) So to find x (Wax weight) we need to divide both sides by 1.1 which gives us x=7.27 Then we get the FO by subtracting as Erica mentioned - We know our candle is 8oz and the wax is 7.27oz So 8 - 7.27 = .73 And there you have it Wax = 7.27 FO = .73 Hope that helps
I tend to make really small batches of candles, and use multiple vessels per pour. I bashed my head against the wall trying to figure this out at first, wondering why I always had "leftover" wax. I was decent at programming spreadsheets on Excel, and finally sat down and reduced all the variables to a master spreadsheet (such as vessel fill weights, etc) to build a candle pouring sheet where I specify what vessels I'm pouring and it does all this math directly. Great for figuring out "how do I use up the last little bit of this FO" too.
Thank you so much for this video!! I thought I understood it correctly, which I originally got from misunderstanding one of your earlier videos. 😂 I even did a double take and verified with candlescience website because the math made sense in my head. Nope, I was completely wrong!! I'm glad you posted. Thank you!!
Omg!! THANK YOU!! I've looked up so many different calculators to try and figure out the weight and it's all been so confusing! Your explanation makes SO much sense and my brain is happier now!! I watched your other 2 videos you pinned, too. Love it! I feel so much more confident figuring out this math. I even created a spreadsheet that I can understand based on your formula. Thank you! ❤❤
I'm looking more into label requirements... is the fillable weight that we calculate with this formula the net weight we are supposed to put on the labels?
I just want to say, that I watch so many videos regarding the fragrance oil % and I ran into your videos. I am so grateful For you! I followed your way and every single one of my candles had alot of CT and HT. It works! Just last night I tried another method and had a whole bunch of wax leftover....so, I will definitely be using your math. Thank you so much for all your videos.
@MemoryBoxCandleCo, thank you for the videos and my apologies if you stated and I missed it, but is the fill weight in fluid ounces or just ounces? Thank you
you just multiply wax amount by 8 and fragrance oil amount by 8. there is a company called candle shack who have an online calculator to work this out for you x
omg thank u so much!! today i made my first candles and i was STRUGGLING. can u please make a video abt the infrared and digital thermometers and which one in ur opinion is the most accurate? i was struggling with that as well 🥲
If you’re just starting out I recommend both for different reasons! Get a probed thermometer to get an accurate reading on wax temp, and use the infrared to read the temp of the glass when doing testing! ❤️
