Flexible Silicone Soap Loaf Mold with Wood Box

My Ride-or-Die Soap Mold

This is the soap mold I use for almost every batch I make — I think I own at least ten of them! It’s my go-to for cold process soap because it produces consistently beautiful bars, is super easy to unmold and clean, and allows you to scale up or down without sacrificing quality. Each mold makes about nine thick, satisfying bars, which is the perfect batch size for small production runs, farmer’s markets, gifting, or filling your own shelves at home.

One of the reasons I love this particular mold is that the loaf size helps maintain better heat distribution. When you scale up soap too much in a single container, it can fail to saponify correctly — but this mold keeps your batches contained and predictable. If you're taking my soap course, this is the mold you’re going to want on hand.
