Candybee Posted July 20, 2018 Share Posted July 20, 2018 I used to have this written down in my recipe spreadsheet so I could figure out the amount of oils needed in a recipe to fit my molds. It was on my old comp that died so its gone. Does anyone have it and can post it here. I need both the one that works for column/slab molds as well as the one for round molds. Thanks.

Jcandleattic Posted July 20, 2018 Share Posted July 20, 2018 (edited) LxWxH = V Length x Width x Height = Volume I thought there was more to it than that, but that's what I have in my notes. Edited July 20, 2018 by Jcandleattic Quote Link to comment Share on other sites More sharing options...
Sponiebr Posted July 20, 2018 Share Posted July 20, 2018 (edited) I use V*.43= Oils in oz. So 12x12X2 mold would be: 288*.43= 123.84 oz. (124 oz.) 3.5*2.75*12= 115.5*.43= 49.665. Volume for a tube: V = π*r2*h*.43 (radius is 1/2 diameter or D*.5) SO! 3" x12" column mold: 3*.5= 1.5 1.5*1.5=2.25 2.25*3.1416*12=84.8232 84.82.32*.43= 36.473976 HTH!

Jcandleattic Posted July 20, 2018 Share Posted July 20, 2018 HA the x .43 is what I was missing. I new it had to be something more. Thanks Sponie 1 Quote Link to comment Share on other sites More sharing options...
TallTayl Posted July 20, 2018 Share Posted July 20, 2018 The .43 depends on your water discount... Can be slightly higher or lower, but in the ballpark. I figured out my standard soap bar size uses 3.6 ounces of oils and double-check for all mold calculations against that. This ensures the same bar thickness and width - all bars come to the same heights in every mold. 1 Quote Link to comment Share on other sites More sharing options...
Candybee Posted July 20, 2018 Author Share Posted July 20, 2018 I was close. I remembered my formula for column/slab molds was something like L x W x H x 4 = oil wt. It was the 4 that was throwing me. Its .43. Thanks. Okay I have to have an easier non math symbol formula for round molds. I remember L (length) x radius x radius = oil wt. But isn't something missing? Quote Link to comment Share on other sites More sharing options...

But isn't something missing? on the round mold one your non symbol formula looks to be missing the x 0.43 at the end isn't it? Quote Link to comment Share on other sites More sharing options...

ncraiders Posted July 21, 2018 Share Posted July 21, 2018 lol for those that did not understand what that image was getting at it was that for round molds you use this formula to get the weight of oils. 3.14159* x radius x radius x height x .43= oil wt Sponiebr was just having a bit of fun telling Candybee the part of the formula they were missing. 1 Quote Link to comment Share on other sites More sharing options...
