While you can heat the bottom of our Pot Tipper, it is not recommended as a permanent fix for heating your oils. Direct heat makes it very easy to scald your oils and damage them permanently. A lack of heat dispersion can create the same dead oil that would come from a fryer - taking away the entire purpose of using high-quality oils.   We always recommend heating your oils in a Double Jacketed Oil/Wax Melter. The water jacket ensures dispersed heat, eliminating the possibility of scorching and ruining your oils. Not to mention that they increase efficiency in your soaping by making large batches a possibility.
