I use Sodium Lactate at 2% in my soap. I still wait at least 24 hours to cut. Some batches seem to take longer still. I think it has to do with the FOs I use because my recipe is the same accept the liquid used. <shrug>
I used to be impatient too :D

I really like this 4 loaf mold. It makes really cute 1# loaves. The side do not bow much at all and its really great for testing out fragrances and recipes.
Oh yeah you can use it just fine. I was the same way when I first made them. :D However wait till you use one that is at least 2 months old or even older!
