Right now I use molds that hold 2.5 lbs of soap, or 40 oz/1113 grams of oil. I usually buy fo's in 2 ounce sizes because most are 5 or 6% usage rates - which is often 1 ounce per pound of oil. So, at 40 ounces this mold goes slightly over the size recommended for 2 ounces of scent. But for sake of convenience - one mold needs one 2 ounces bottle of fo. Make sense?
I'm having some custom molds made for fix some issues I've been having. One of them is getting 10 bars out of the loaf, instead of 9 bars. It's silly I know, but the 9 bothers me as it's an uneven number.
The new mold I want, is even bigger by about 5 ounces - so 45 ounces of oil per mold - which is 13 ounces of oil than the 5% usage rate. Now, with the old mold, I've been happy getting away with using slightly less fo for the size of mold, and happy to prevent needing to buy larger bottles. But I suspect the larger new mold will really challenge that; resulting in weaker scented soaps, or smaller bank account now that I'll have to buy 4 oz bottles to make one loaf....then have leftover fo in the bottle that won't be enough to make a second loaf until I order more.
Do you agree that stretching the fo to cover 5 more excess ounces of oils will decrease the strength of the scent enough that I should just suck it up and stick with a 9 bar size? Or do you have any other ideas?
