    Product description

    The slab liner will hold approximately 60.8 ounces (3.8 pounds) of oils and will make approximately 4 pounds of soap. The soaps made in the slab liner can be cut to any width or length you prefer and many different sizes are possible. It's all up to you!

    Basic, Premium, or Handle Mold?

    We are often asked about the difference between basic and premium molds.

    Basic Molds:

    • Have a wooden box to support the liner.
    • Have holes in the bottom of the wooden mold to push out the liner.
    • Do not have a lid.

    Premium Molds:

    • Have a wooden box to support the liner.
    • Have a clear lid to view soap as it gels and prevent soda ash.
    • Have grooves in the wooden mold box the lid slides into, creating a seal between the soap and outside air. This is the main method of preventing ash.
    • Have removable sides for easy removal of the liner.

    Handle Molds:

    Handle molds come in basic and premium styles. They provide the ultimate ease of use when making soap. The lip of the liner surrounds the wood mold and keeps it clean. The handles on the liner allow for very easy removal from the mold. 

    However, the sides of the wooden mold box are not removable in the premium style, and the basic style does not have holes in the bottom of the box for removal. This is because you can simply lift up by handles and the liner pops right out! Another benefit of our handle molds is the silicone is thin yet sturdy, making soap a breeze to remove from the liner.

    If you do not gel or cover your soaps, basic molds are best. They can be covered with cling wrap to prevent ash. If you prefer to gel your soaps and want more ease of use, premium molds are ideal. Handle molds offer the best of both worlds in premium and basic styles.

    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.

    Love it...but a lil too short?

    I love how well made this mold is, including liner....I just wish the height was littler higher...My suggestion is to move the .25 off off the length of 9.25 to the 2.63 height the final would be 9 "L x 6.25" W x 3" H... to me it would be perfect size...

    My favorite mold

    This is a great mold. Well made, strong silicone that doesn't bend in. I get 18 bars so it's perfect for soaps that are popular sellers. Just bought a second one!

    Wish it was deeper

    It’s not as deep as I would like it. When I cut it into loaves, it’s a bit smaller than my single loaf bars. I did notice that it needs a little over 80oz of soap to fill the mold completely. I can 18 bars and some samples

    ❤️ this mold

    Sturdy mold with thick silicone liner. I bought this specifically for sample bars as I have a couple of your five lb molds. This will be a repurchase for me. Arrived today and I just couldn’t help myself.

    I've everything I always order from you. I haven't used my 4lb slab mold but loved. Can't wait to try it . Thank you so much

    4 lb Slab Mold

    This mold is perfect for me. I have only been soaping for 1 year and wasn't brave enough or confident enough to go for a really large mold that uses a lot of oils ($$$$$). I love using this mold. I use this mold the most. Design possibilities are endless with a slab mold. You can cut the bars any way you want and to any size you want. With no waste at all I am able to get 18 bars, 2.125" x 3.00 x 1.2"
