hello everyone. i'm very new to this and have started a little tiny business out of my kitchen :) i'm doing container candles w/essential oils. my question is...when adding stearic acid(hoping that this will make the cracking go away), how do you figure out the percentage to use? i've read that 3-5% is suggested...if i'm using 2 cups (16 oz) of phytowax to make an 8 oz. container candle, then i should use .8 oz of stearic, right? how the heck does that translate to something i can measure if i don't have a scale...i know there's probably a table somewhere that converts this but it eludes me.
