you can make everything in them, they are awesome! Even the ones that are not silicone but are a ice cube tray type of plastic can be used to make candles. When I make my lip balm recipe, I make a pot full and then pour them into ice cube trays, each tray makes 4 lip- balms, so I can make small batches for flavors, and only make a big mess once, the cubes melt in the micro in about 45 seconds.
