BargainRollBack 2 pack X Oval Shape Homemade Soap Mold Chocolate DIY Tray Mould Silicone Party maker (Ships From USA)

I bought these because I prefer a rounded shape when making soap. I find they have a more ergonomic hand-feel and I just prefer the look of them. These molds did not disappoint. They are thick, sturdy, easy to clean, easy to handle, hold their shape well -- they're silicone molds. I don't think I've ever come across a bad silicone mold, and this set is no exception. I would recommend this product, absolutely.However, one crucial thing that is missing from this listing is the weight or volume of each cavity so we can calculate our recipe with as little waste as possible.I used my SoapMaker program to calculate the recipe for me, and we predicted that we would produce 12 bars weighing ~2.7 ounces a piece with only 0.5 ounces of excess, and that is exactly how it happened.When we multiply 2.7 ounces by 12 cavities total, we get a total volume of 32.40 ounces for the two of them combined. When we divide that by two, the product is 16.2 ounces per six bars of soap. Divide again by the six cavities for the final figure of 2.7 ounces a piece.I did use a 26% water discount, so I experienced very little shrinkage due to the low water content I used. I would say the math is pretty accurate but not exactly so. I do believe the dimensions may be incorrect because the math would imply that the total weight of water in one cavity would equal 4.1 ounces of water, which simply isn't true. The actual weight of water per cavity is 2.55 ounces. I'm not sure where the math got muddy, so I just guessed based off the water weight, my water discount, and my additives. I predicted I would need 22.5 ounces of oils so I worked with that figure and had great luck.TLDR; there's nothing wrong with these molds. They're great molds, in fact. I just wish there were specs about the average weight of soap per cavity so I didn't have to figure it out. If you like to calculate your recipes and/or resize them, I would plan for at least 2.5 ounces if not 2.7 ounces of soap per cavity (~70 to ~76 grams). Enjoy :)

Great for soaps

Got these to make breastmilk soap and they were perfect!

I used these to make homemade shampoo bars. Great quality. Easy to use. Easy to clean. Very flexible.

While they look pretty after assembled, it used a lot of chocolate.
