Made olive oil soap 2-weeks ago, still soft enough to take a thumbprint. This is my 5th try, same recipe, doesn't seem any harder than the previous batches. Am I expecting too much from sodium lactate?

It's stashed on a BBG grill inside the house's HVAC intake. Usually a great place, but we're not running heat or air ATM. 🤷🏻

Should I try gently baking it? Scared to ruin it, can't really afford more olive oil. One reason I roll my own soap is to save money. We burn through a bar of Irish Spring every week. My previous olive oil bars lasted me (alone) a month or so.

I made some mistakes with my first batch and learned from them. I still see a few issues here, mostly from panicking as the batter thickened and starting off a little too warm because I noticed my mixing bowl had a tiny hole that was leaking oil so I mixed the lye and oil a bit hotter than I should have, they were still close in temp though.
