mlomeli Posted January 11, 2011 Share Posted January 11, 2011 I ordered 2 10lb slabs of wax. One pound is 16oz. in weight. We got 1oz. samples (our first venture, samples are awesome). My question is...Is oz. Equal in wax vs FO? When a wax says up to (but no more) than 5%, how does one figure the math? Is that like half an oz per pound? Yes, this is an extremely easy question to answer, but I suck at math... Quote Link to comment Share on other sites More sharing options...
Guest Expressive Posted January 11, 2011 Share Posted January 11, 2011 Average rule of thumb is 1 oz. of FO to 1 lb. of wax. Quote Link to comment Share on other sites More sharing options...
Wessex Posted January 11, 2011 Share Posted January 11, 2011 When making candles, all ingredients are weighed. When you get a sample FO, it weighs one ounce. It is not a liquid measure. One ounce of FO to one pound of wax will give you approx. a 6% FO load.Cheers,Steve Quote Link to comment Share on other sites More sharing options...
mlomeli Posted January 11, 2011 Author Share Posted January 11, 2011 Awesome, thanks.Follow up: if a wax says "over 5% can cause surface oil", would you add slightly less than the 1oz vs. 1lb.? Quote Link to comment Share on other sites More sharing options...
Judy, USMC Posted January 11, 2011 Share Posted January 11, 2011 (edited) Here's the math the way I figure it:16 oz wax + 1 oz FO = 17 oz total 1 ounce is 1/17 of the total weight.So divide 1 by 17 and you get 5.088% which is the pecentage of oil contained in the total weight of the scented wax.Some oil will cling to the inside of the bottle ... I wouldn't worry about it and use the whole ounce. You should be fine.The way Wessex is calculating is probably 1 ounce divided by 16 which is 6.25%. 5% of 16 would equal out to .8oz. It may be best to call the supplier and find out which method they advise you to use. Edited January 11, 2011 by Judy, USMC Quote Link to comment Share on other sites More sharing options...
Wessex Posted January 11, 2011 Share Posted January 11, 2011 I should have clarified, my bad. I use 15 ounces of wax and 1 ounce of FO to get a pound of product at about 6% load. Wasn't thinking as I typed. Cheers,Steve Quote Link to comment Share on other sites More sharing options...
mlomeli Posted January 11, 2011 Author Share Posted January 11, 2011 Ok, cool. Thanks for the help. We are starting tomorrow. This is going to be fun! Quote Link to comment Share on other sites More sharing options...
radellaf Posted January 12, 2011 Share Posted January 12, 2011 I use this formula, as I tend to start with some amount of wax an want to know how much FO to add to get a desired percentage:FO = P*Wax / (1-P)e.g. for 5% add (0.05*Wax)/0.95Rework a bit if you want to compute based on total weight of wax+FO, but it's not that far off, and I usually weigh out wax first and then add however much FO. Units have to be the same, and it's a pain that additives are usually in grams and wax in pounds. I convert and do the math in grams because that's what my glassware is marked in (1ml is close to 1g, exact for water, a bit off for FO). TBS and TSP have no exact conversions, you just have to see what a TBS of whatever it is actually weighs using a precision scale if you want to get to percentage measurements. When making single 8oz candles with some additives where 1-2g is all that's needed, 'spoons just won't cut it. Quote Link to comment Share on other sites More sharing options...
IwantItgreen Posted January 13, 2011 Share Posted January 13, 2011 I use a parasoy blend and found out that 2g/lb comes real close to 7%. So if I'm pouring a tester, I have 8 oz. wax and 16 g FO. 8 x .07 = .56 16g=.564oz. Quote Link to comment Share on other sites More sharing options...
