Solid oil weight verses liquid weight. Hi fellow soapers, Using my scale, setting at 0 to subtract weight for the container, I weighed out kokum butter, tallow and coconut oil. My total weight is 39.4 oz. After melting the weight is now 53.3- 8.5 for my container which is now a total of 44.8. I assume solid weighs more than liquid. Are the weights on soap calc for liquid weights?
