Unfinished Baltic Birch Wooden Mold (18 Bar): Bramble Berry adoringly calls this wooden mold "The Best Soap Mold in the World!" This 18 bar wooden mold is made out of top grade Birch Plywood and holds approximately 6 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 18 bars of soap that are 2 7/8" long  x 1 15/16" wide and up to 2" tall. Our 4 1/2 pound batch of Cold Process soap made 1 inch tall bars of soap.

Silicone Liner: Make using this mold even easier with our custom made silicone liner. This will replace the side inserts and you will never have to line your mold with paper or plastic again. The bar divider inserts fit in the mold perfectly. But we have found that the lid needs to be flipped over to the flat side for a close fit.

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

2 Long End (border) Pieces: 13 1/16" Long, 2 1/8" Wide, 1/4" Thick
2 Short End (border) Pieces: 9 3/16" Long, 2 1/8" Wide, 1/4" Thick
2 Long Divider Pieces: 12 1/2" Long, 2" Wide, 1/8 Thick
6 Short Divider Pieces: 9 3/16" Long, 2" Wide, 1/8" Thick

Baltic Birch: 11 1/4" Wide, 14 5/8" Long, 3 1/2" Tall

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.

Silicone Liner: A silicone liner is available for this mold and is sold separately. The silicone liner is a single unit lining method meant for use in place of the plastic border pieces and plastic bottom insert while still being compatable with the plastic dividers. The silicone liner is compatible with both melt and pour and cold process soap making. It is not necessary to line the mold with freezer paper or plastic when using the silicone mold.

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.

Finally can do larger batches!
Up til I received this mold, I was doing small batches (2lbs at a time). But, with this mold, I was finally able to step up my game! 5-6lb batches make things much easier when you are a small shop getting established. I also purchased the silicone liner, and that has been a blessing, too...much easier to unmold once it's ready. The only reason for the 4-star rating is that the bars come out a bit smaller than I prefer (usually make 5-6oz bars), so they've been largely unusable (I use the long pieces, but don't use the cross bars...a bit tricky, but I make it work). Thanks for a fine mold...I'll probably be ordering another soon!!

Bent dividers
I love the mold but I couldn't give it an excellent because when I received it the dividers were all put together an inside of the mold the mold was them placed in the box standing on its end and the heat through delivery had caused the dividers to warp. Being a little OCD of a soap maker it drives me crazy that the bars in the center places on both ends and sides flare out and I don't have completely straight nice even bars. Other than that I love the mold, I love the liner. However, I just wish that the inserts have been maybe all stacked together and wrapped up and not actually inserted inthe mold.

Love it, but bars are small.
I love it! The bars are a bit small for my taste though with the dividers, So I'm just using the mold without dividers and hand cutting. I may even try just using 1 of the dividers to essentially get two loafs side by side. Love the mold though, it's so nice! I also have the liner too.

I just love it
Although I think it should come with the bottom piece or a liner for that price, this is a great mold that will allow your creative movements to be expressed. I just love it.

Not happy with the dividers
The mold and the silicone liner are just wow, I'm really happy with their looks and quality. But when I look a bit more carefull, the dividers don't fit the mold (of course with the lids/silicone liner in). I suggest Bramble Berry should control the quality of the divider more carefully. I really can't use them and have to make my own dividers.

Terah from Bramble Berry replies...
Hi Huy Nguyen! I'm glad you're happy with our 18 Bar Unfinished Birchwood Mold and our Silicone Liner for 18 Bar Mold! Though, I'm sorry you were disappointed with the dividers. The dividers will fit inside the silicone liner, just not the side inserts (the liner replaces these). See how the dividers are assembled when using the silicone mold in our How to Assemble Dividers for Birchwood Soap Molds tutorial (this specific part starts at about 0:40). Also, the dividers do expand when they get warm, so they are made to be a bit smaller than the mold. This allows room in the mold for when the soap goes through gel phases and makes the dividers much easier to place!
