There are many types of molds to use for making soap. I have used jello molds, plastic molds, milky way molds, silicone molds,etc. Here are my opinions on these molds.
Jello molds are cheap and have many shapes. Ssome of these molds work okay but many don’t work well. The soap does not pop out easily and the molds get out of shape after a couple of uses.
Plastic molds such as the candy molds are what I first tried because they are cheap and easy to find. You can find a variety of shapes but these molds also don’t last long. I have found spraying a little rubbing alcohol on the molds help the soap to pop out better.
Milky way molds are my second favorite mold type. These cost a little more but are still fairly cheap. They last for a while and don’t get out of shape as easy as other molds. Tthe soap does pop out easier especially if you spritz the mold with alcohol.
My favorite mold type is the silicone molds. They are a little spendy but will last for a long time. You can find a variety of shapes and the soap pops out very easily. You don’t even have to spritz with alcohol. My advice is to spend the extra and use the silicone molds. Your soap will come out looking better.
