The most common and widely available bath bomb molds usually produce ball-shaped bath bombs, and they are typically made from either metal or plastic. Metal molds are usually a little more expensive than plastic molds, but they are also more durable. Bath bomb presses, on the other hand, are usually very expensive, but they are much faster and more efficient than regular molds. If you are unable to obtain a bath bomb mold or press, you can use any number of things to mold bath bombs, including Christmas ornaments, ice cube trays, muffin tins, or candy molds.

Like most bath bomb molds, a metal bath bomb mold produces ball shaped bath bombs. These are usually made from either stainless steel or aluminum, and they typically come in two pieces. Bath bomb makers pack each half of a mold with the bath bomb mix and press them together for a few minutes.

The major advantage of metal molds is that they are very durable, and will virtually never crack or break. A plastic bath bomb mold, on the other hand, is more likely to break than a metal mold. This type of mold, however, is generally less expensive. If you have a limited budget, you may want to consider investing in plastic molds.

Bath bomb molds also come in a wide rang of sizes. Some of these molds can make small bath bombs the size of golf balls, while other may make them as large as soft balls. You should be careful when using a large bath bomb molds however, since large bath bombs do not stay together as well as small ones.

It can be a time-consuming process to make several bath bombs with one single bath bomb mold, though. If you have an established bath bomb making business, you may want to consider investing in a bath bomb press. You can shape several perfect bath bombs in minutes with these devices, simply by pulling a lever. They can be rather expensive, though, and one of these machines may be a waste of money if you are only making bath bombs as a hobby.

A bath bomb mold is not necessary for making bath bombs because you can mold these balls with your hands if necessary. You can also use a ball shaped plastic Christmas tree ornament that comes apart. Candy or soap molds also can be used. Large and small muffin tins, as well as ice cube trays, can be used to make small flat bath bombs, sometimes referred to as bath bomb tablets.

This might sound funny, but I actually use a steel meat baller as a bomb mold. It's so much easier to use than a regular steel bath bomb mold because it has handles.

@fBoyle-- You can definitely use silicone molds used in cooking and candy making for bath bombs. I have used them many times and they always work great. In fact, I think this type of mold is better than plastic and metal molds because it's so easy to remove the bath bombs. Just leave the mixture in the molds to dry and pop them out when they're ready. Silicone gel molds bend easily so they do not cause the bath bombs to break or crack in the process.

If you use a metal or plastic mold, you will have to remove the bath bombs from the mold when they are still wet and place them somewhere to dry. Otherwise, you won't be able to get them out without breaking them. And it's usually more messy to use plastic and metal molds.

Has anyone used silicone gel candy molds as bath bomb molds? Do they work well?

This is the only type of mold I have at home and they have nice designs, so I think the bath bombs would look pretty. But I'm not sure if they will make the process more difficult because they are not typical plastic molds.
