18 Bar Rectangle Grid Bar Tray mold specifics:
Measures 13.5 in. X 10 in. X 1.5 in. deep. Makes 18 bars measuring 2 1/4 x 3 1/4. Each bar is approximately 4.2 ounces. This tray mold is ideal for volume production. The grid makes cutting a breeze and ensures bars are uniform in size. Pouring temperatures should not exceed 145 degrees F. Pouring above these temperatures may warp or damage the mold.
Why are the corners of this tray rounded?
This has to with design issues that can get pretty complicated for the average person. In a nutshell, the rounded corners create a stronger mold that last longer as webbing issues do not occur with this corner design. Webbing issues have to do with the way the plastic extrudes and thinning of plastic can occur creating weak spots in the design. The depth and size of the mold are key factors. With smaller areas (such a smaller tray molds) webbing issues and extrusion issues are not a problem. If the corners were perfectly square on these large slab trays, the mold would be weakened due to webbing and the corners would readily crack when soap is released. We extend the corners to allow the soap maker to trim the corner into rectangular shaped bars that are the same size as the rest of the bars. Honestly, it's a pretty clever way to make sure there is no waste and the mold remains strong.

Mold size and pouring temperature of soap will determine set up time. It is imperative that you allow soap to cool completely before trying to remove from any mold. Depressions will occur in the top of mold if you try to release soap by force. Allow molded soaps to sit for at least 1 hour for best results. Gently pull the at the sides of the mold. This releases entrapped air between the mold and soap. Using firm, but gentle pressure, push on the top of mold until soap is released. If you are still having difficulty, place mold in the freezer for 10-15 minutes.
Mold Tips for CP (cold process) soapers:
- Do not use oil in the molds, it will make the CP stick more because the traced soap wants to grab onto the oils. When you get a new mold, wash it in warm soapy water, rinse and dry with a soft towel and buff it.
- Use borax in the water before you add the lye. Add 2 tsp of Borax for every 6 oz of water, stir till it's dissolved and then add your lye to it. What this will do is firm up the CP and make releasing it a breeze.
- If the top part of the CP is hard and the bottom is mushy, it might not have had a full trace.
- If using Palm Oil as part of your recipe, stir the oil before scooping it out on your scale. Most soap makers do not know that the Oleic Fatty Acid in the Palm Oil will sink to the bottom of the container as the oil solidifies and the other fatty acids will float to the top. If the Palm Oil is just scooped out from the top of the container, you get a soft soap but as you get to the bottom of the container, you'll find you get a harder bar of soap because the Oleic Fatty Acid has sunk down. when using a 5 gallon bucket of oil, dig a hole down into the Palm Oil and start scooping the oil out from the bottom to the top so you have a mix of complete oil.
- If the CP sticks in the mold... do not force it out but instead put the whole mold into the freezer for 30 minutes, take it out and let the plastic mold come to room temperature which is about 2 minutes. Put a towel on the counter and turn the mold over on the towel, now put your fingers under the mold and gently pull the sides of the mold to allow air in and then with your thumbs on top of the mold, press as your go around the mold. You should see the air releasing it from the mold.
