    Product description

    The 4 lb slab liner will hold approximately 60.8 ounces (3.8 pounds) of oils. It's a smaller slab liner, ideal for smaller batches of soap. It's a perfect beginner slab mold! It will need to be supported by a wooden box to prevent bowing on the sides.


    🧮 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.

    Nice and sturdy

    I really appreciated the thickness of this liner. I'm teaching myself woodworking and built a box to go around it and it works perfectly

    bon comme premier slab mold

    J'aime bien ce moule, quoiqu'il est maintenant rendu trop petit pour mes besoins. Il est très flexible ce qui permet de retirer le savon aisément.

    Nice sturdy mold!

    I love the thickness of this liner! It's so much thicker than I expected it to be. I know it will be perfect for my smaller batches. So pleased with all the quality of Nurture Soap's products!

    4 lb slab liner

    Works great. Definitely holds 4 lbs of soap. (Not soap weight). 18 1 inch bars.

    Exceeded my expectations!

    This slab liner is so thick! Well worth the price. This will surely last a very long time. Extremely pleased.

    Good mold

    I haven't used this mold yet, but I can tell it is going to be a good size to start increasing my soap making. I've been using a 2lb mold and I'm ready to make 4lbs in this slab mold. It seems stiff enough that it doesn't need the wood frame but I probably won't fill it to the very top or if I do I'll support the sides.

    Love love love

    I am just starting up my soapmaking business so I wanted to get a few different sized molds. I am so happy that I went with this one. Very nicely made and the soap slab just slides out like butter.
