It's crazy that 10 years later this is still one of the most valuable KZfaq vids out there. I refer to it at least once a month! Thank you for this!

I feel like such a dunce. I didn’t realize until the other day that the intro to your videos is the beginning of Van Halen’s “Hot For Teacher.” Well played, teach, well played.

Its so refreshing that you want to share your knowledge with soapers thank you. Great lesson wish you were around last year when I started it took me soooo long to figure this out, I hope the new soapers appreciate you I sure do.

You have to be good at math. I flunked math in school. It was my worst subject. Like, where did you get .625 out of 5/8 or .125 out of 1/8? This is going to places where my brain has never been and doesn't want to go.

@KnitandCrochetHeaven What you have will give you the total volume. You then need to multiply that by .39 to get your total oil wieght. So 3.5 x 3.75 x 15.5= 203.44 then 203.44*.39= 79.34 {total ounces of oil needed for your 5 lb loaf mold}. Hope this helps!

@junegoodwin1317 Thanks for watching!

If you are using a soap calculator, something around .39 is the default recommended percent of oils in the recipe. But you can change that number if you like. Your percentage can also be .40, or .55 like one of the other commenters discovered. It's your soap. You decide! :)

@ThreeSistersSoap Thanks for watching. I hope this helps :)

Super cool ! Thanks for the great lesson. Your soap reminds me of pretty girlie lace. Very very nice. Thanks again

@805Soap Aww, thanks for the words of encouragement!

What temperature are your soaping at? This can affect your trace. Try to keep the oils + lye solution at the same temperature.

Castor oil is notorious for accelerating trace. It's wise to limit it to 2% of your recipe. Try using olive oil and coconut oil, or just olive oil. If you use olive oil by itself, it will take a VERY long time to trace, but you will have time to play around with colors and fragrances. BUT remember what soaping101 said about pouring at thin trace: it can increase your chances of soda ash forming. Good luck.

I think your a Pharmacist :-D great video again always going into detail, I've never seen a soaper that does this, keep them coming ;-D

It is so nice that you take the time to make these videos. It would have been nice to have them when I was starting out! I am enjoying them. ;0)

The .39 is your multiplying factor.

Actually, my sister is a pharmacist :) Thanks for watching!

aha,,finally got the irony of your intro music,,lol

This was so helpful. Thanks much!

@ricangem28 You are very welcome :)

Great video..thank you! I hope to see something on how to figure oil percentages soon..

what would the formula be for cm and grams?

Thank you so much!!

@mbjlhj Thanks for the kind words!

Hi and thank you or all your webinars, very useul and interesting! :) I am trying to understand what the .39 coefficient stands for...could you pls assist me? I would like to use your tips to create a new soap recipe, starting from a mold that I have but really don't understand how to "translate" this figure. Thank you!!! :D

sorry, i dont get what ".39" is :/ a coefficent? generic number? in which measure is expressed? i tried to make a proportion in grams and cm, i think it's some number around 6,75 (maaaybe) can you please express your calculation also in grams and cm? pleeeeese :D

How do you get the soap out of the Pringle's can mold? Do you have to chill it in the refrigerator and then push it out the end or do you cut the can? Thank you for all of the informative videos, they really help. :)

@mukwah1111 I agree :) Lace it is!

Nice subject. I am glad you did this subject since I usually guess at what I need which I was having some overage. Now I can plan better on my oil useage. No surprises this way. Very informative video. Thanks for taking the time to do it. Love your video's by the way....

@soaping101 I feel really dumb now. The calculation were actually correct. I didn't realize I had a 7 pound mold. I thought it was only 5 pounds and couldn't figure out how the excess with the lye and the water was going to fit in there. I spent 2 hours relearning fractions to find out it was correct after filling it with water and measuring it. Well... atleast i remember how to do fractions and decimals. :-/

@kangakangaboi Yum-o!

I really liked the idea of this video, it's just what I was looking for but.... Why .39, what's that come from and how did you know the amounts of lye. So it seems like if I follow this process I'm missing some key steps to get to the total

pie is a food! I'll have to figure out another way! LOL Yes I am related to dumb and dumber, we are all first cousins! Thanks anyway.

I think we skipped a step. My calculation are coming out wrong. I don't think I am putting my inches in the correct format. I have a 3 and 1/2 inch x 3 and 3/4 inch by 15 and 1/2 inch. I am multiplying by 3.5 x 3.75 x 15.5 I didn't calculate this correctly have I?

The .39 is your multiplying factor.
