    Product description

    Please note our current 12 lb slab liners are white. They function the same. The color is the only difference.

    Our 12 pound silicone slab or tray mold liner holds 130 ounces (8 pounds) of oils maximum. It is made from premium food-grade silicone that will not stretch or tear over time. This liner is heavy duty!

    These liners go through a special process that creates cross-polymer links in the silicone to make our molds extra strong and durable. Because of this process, the liners may vary slightly in size from batch to batch. It is strongly recommended to buy liners and wood boxes simultaneously to ensure accurate sizing of the liner and the wooden mold box. See our complete mold sets.


    🧮 Lye Calculator

    How to calculate the volume of a mold:

    1. L x W X H = ? X .4
    2. Example: 18 x 3.5 x 2.5 = 157.5 x .4 = 63 ounces of oils
    3. This is the maximum amount of oils that can be used with this size mold.
    4. Use any mold and calculate the max amount of oils the same way.

    so far so good

    Has worked well Although I haven't had time to use it much yet. Also it was white not the green mold that I was expecting.

    Kaci Tiller (Bel Air, US)
    It's so great!

    I made my first slab in this the other day for a custom order and it performed beautifully! Soap unmolded like a dream, and it has very sturdy sides.

    The slab mold is a great investment

    I bought two silicone slab molds to up my soap production, and I couldn't be happier. They're sturdy and well-made. My husband made a wooden box for me, but I would have bought the complete set if he didn't have the time to make one. Overall I'm very happy with the purchase, and I may buy more!

    Sarah Chaney (Columbus, US)

    This mold is my first slab mold and I do have to say it is structurally sound and pretty simple to use. I made a mold box for it no problem. My first pull was no problem at all. It came out clean.

    This mold is fabulous for my big batches!

    This liner works just as I expected, perfectly. I use my slab mold and with the liner all the time and am so glad I bought not one liner but two.

    I just used this liner yesterday and the soap came out beautifully. It is nice and sturdy, the soap released easily and was a dream to work with.
    Thank you.
