Product Notice, January 9, 2024: This product has been discontinued due to low sales. Stay tuned for exciting new product announcements!

Our 9-bar large square slab tray mold is made from food grade plastic and can be used with melt & pour soap bases as well as cold process soap. This mold makes one slab of soap that can be cut into 9 square bars, making it easier to produce larger batches of soap.

Each bar measures approximately 2.5" x 2.5" x 1" (6.4 cm x 6.4 cm x 2.5 cm) and holds 3.5 ounces (weighted, or 99 g) of base. The entire tray holds 2 lbs (907 g) of soap base. We recommend allowing your soap to cool for 24 hours for easier removal from the mold. If the bar won't release, place the mold in your freezer for 30-40 minutes and try again. We also recommend pouring your soap base at a maximum of 145°F (62.8°C).

It's best to hand wash the mold with warm soapy water. Cleaning in the dishwasher or with hot water can warp the mold.

This mold is very easy to use - the finished bars look like jewels with the beveled edges!
