i think i am starting to 'get' this sap chart stuff, maybe! ok, i make a simple bar with CO, lard, GM and OO. in my area, the oo is terribly expensive so i was thinking to sub with something else? sunflower is not possible here, but canola and safflower is easy to get and cheaper. i seen a chart saying that all are within the same range of 185-198, and a lye of .133 to .134. since these values are so very close, does this mean i can use one of the less expensive, easier to find oils in place of the oo? or is there some other reason (slimy bars? snotty soap?) not to use some of the sub. oils? also, i have only gotten FO from 2 places, one place had 1 oz jars, one had 2 oz jars.the soap made with the one with the 1 oz jars smells as strong as the other with 2 oz jars of FO. are some places selling less-strong FO? i am using a recipe that makes around a 4lb loaf of soaps. the 2 diff. 'brands' of FO seems the same strength even tho one used half as much as the other. how much is generally used per pound of soap? thanks for anything you can tell me!
