Unfinished Baltic Birch Wooden Mold (36 Bar): Bramble Berry adoringly calls this wooden mold "The Best Soap Mold in the World!" This 36 bar wooden mold is made out of top grade Birch Plywood and holds approximately 10-12 lbs of soap. The wood on the sides and lid is nicely sanded but completely raw and unfinished. The base of the mold has a lacquer finish. You can add a wood finish yourself or just use the mold as is and allow it get that lovely, used patina as it ages. Each wooden mold is custom made and locally hand crafted here in Bellingham, Washington. All of the joints are glued and nailed together. Makes 36 bars of soap that are 2 7/8" long  x 1 15/16" wide and up to 2" tall (depending on your recipe).

We love this mold for making beautifully swirled soap. Learn the secrets of making perfectly swirled soap in this 13 minute online video.

More Details

About the Dividers: The liners and dividers are made from a flexible plastic that can withstand constant temperatures up to 200° F (but please do not subject them to temperatures over 200° F). There is a top and a bottom to each divider. The top is slightly rounded with an even rippled texture. The bottoms are cut flat with slight angled cutting marks. All of the flexible, plastic dividers are slotted to easily slip together. If any of the dividers appear to have taken a curve to them, you can easily bend them back straight.

About the Lid: Made from the same beautiful Baltic Birch Plywood as the body, the lid has an inset piece of plywood allowing it to fit perfectly snug on top of the mold.

Lining Your Mold: We suggest lining your mold not matter what type of soap you're making. For cold process, we recommend lining the entire mold with freezer paper. If you're making melt and pour soap, we suggest lining the entire mold with plastic (plastic drop cloths work great!). Line your wooden mold before adding the insert pieces.

Using the Dividers: You can insert your dividers before or after you pour your soap depending on your preference (Anne-Marie likes to put them in after!). Before adding your dividers, make sure that you have lined your mold. The end pieces slide in first- match the long pieces with the long sides of the mold and the short pieces with the short sides of the mold.. Then put the dividing pieces together and place into the mold as a complete unit, using both hands. Use your thumb and forefinger to squeeze the long dividers together slightly so they will not drop apart. Then gently place the unit into the mold.

Bottom Inserts:  Bottom inserts are sold separately and go into the bottom of the mold before all of the divider pieces. Anne-Marie likes to use the mold without the bottom insert but if you would like a perfectly smooth finish on the bottom of your soap, we recommend getting one.

Great Mold
It's a great mold, I have the bottom insert which I cover in freezer paper. And I use the inserts with a bit of mineral oil (first time I used it I hadn't read the instructions and man it stuck good! I wish the inserts fit perfectly, but I have a 1/4" or so gap on the edge pieces and on the separators. I've just trimmed off the funny edge I get on the soaps. If the separators warp a bit I just bend them a bit, and or use warm water to adjust them. Overall it's a great mold and I wouldn't mind having a second one.

Recieved my mold today after a loong wait, didnt know the dividers werent going to be a perfect fit for the mold as there is a quarter of an inch gap between liner and dividers as if the dividers arent long enough. if dividers fit this mold wouldve had great potential disappointed :(

Hi Jakira!  I'm so sorry you were disappointed with this product! The dividers should be a perfect fit for this mold so it sounds like you might have gotten a defective set of dividers.   I will email you personally to resolve this issue!

Great, but no liner?
I inherited this mold from a friend going out of making soap. I plan on buying another, it is a beautiful mold, but I don't see the matching silicone liner? The other slab molds have them, but not this. I feel like that is a real shame. Having a matching liner would make this mold perfect.

Reply from Bramble Berry
Hi Vanessa! I'm so glad you love our 36 Bar Unfinished Birchwood Mold! Though, I'm sorry we do not have a matching silicone liner for this size of mold.  Thank you so much for your suggestion!  We'll definitely keep that in mind.  In the meantime, learn how to easily line your mold with freezer paper with our How to Line Any Mold blog post. I will email you personally to discuss this further!

Exceeded my expectations
I got this mold 2 days ago and couldn't wait to try it. I used the Peacock Swirl base recipe which uses a lot of olive. I normally pour 70 lb. batches at a time (haven't used olive oil for years), so reformulating and pouring this "small" batch was a huge change for me. Ok..back to the mold itself. It is very well made! I was really surprised at how strong the rabbit joints on the corners are and the wood used is #1 rough edges anywhere on it! When the 12 lb. batch didn't completely fill it to the 2" deep limit, I mixed another 6 lbs. and overfilled it by about 1/8", but in the end, the bars (though a bit challenging to get out of the mold JUST because I poured them so dang big), were gorgeous and I saved 12 to sell as big ol' fat bars (around 8-9 oz) and cut the rest of them in half yielding a total of 60 bars plus 19 more from another mold. Next time, I'll probably not pour so thick. The plastic dividers and side pieces were a snap to slide off the bars. LOVE IT!

I love this mold. It's extremely well made and sturdy. The dividers do a great job--a swipe of mineral oil makes sure that the bars release easily. It's perfect for salt soaps.
