“Atlas” Slab soap mold with silicone liner

Big batches need a mold built for the job. Meet Atlas — our 15 × 15 × 4″ heavy-duty slab mold for soapmakers who need serious capacity without sacrificing precision or durability.

With a generous 900 in³ (14.75 L) capacity, Atlas holds approximately 22.5 lb (10.2 kg) of oils when filled to its full 4″ height. The square 15 × 15″ footprint gives you plenty of flexibility when planning bar sizes, batch heights, and production layouts.

We build Atlas in our workshop from durable materials chosen specifically for soapmaking. Its sturdy outer structure supports the weight of large batches, while the hand-poured silicone liner makes unmolding easier and eliminates the need for disposable liners.

Like our other slab molds, Atlas is made for more than an occasional batch. It's a production tool—designed for growing soap businesses, larger batch days, and makers who prefer pouring more soap at once.
