Oh no, you realize that glycerin rivers are just cosmetic, right? Some folks try for them on purpose because they like the look.


If you don’t like them, the easiest way to avoid them is to reduce your water. Did you use the same amount of water for your CPOP batch as you would for HP? If so, that’s the most likely cause in combination with the added heat. TD doesn’t cause them, but will make them more prominent/ visible.


I gel almost all my batches on a heating pad (another way to CPOP) and almost never get glycerin rivers. I typically use 40% lye concentration, but even at 33%, it’s rare for me.


If you still get them after reducing your water, then for your recipe in that size of batch, you may not need to CPOP to get a full gel; simply covering and insulating may be enough (assuming the room temp is not too cold).
