Making my own silicone molds has turned out to be surprisingly simple and I'm very happy with the results.
Silicone molding putty is sold next to the polymer clay (Fimo) at the craft store and costs about $20. That may seem like a lot of money for a small box of putty, until you realize how many molds you can make with that small amount.
The box contains two containers of putty, one white and one yellow, that must be combined. After the white and yellow putties are mixed together, following package directions, a hard object is pressed into the putty or the putty is molded around one side of the object. This object can be anything, a piece of jewelry, a shell, a rock, a toy, an original design made of clay and hardened, or another mold that you want to duplicate (I did that with the zeppelin candy mold, because I've wanted more than one of those for a long time).
After only 20 minutes, the silicone is set up enough to remove the thing that has been pressed into the putty.
It is recommended that molds used for food should not be used for other things to prevent contamination. Also, if the mold will be used for food, wash well with soap and water, and let dry completely before use.
The molds can be used for many things, such as candy, Fimo creations, candles, cookies, and soap. I made three molds for small guest soaps:
and I tried a little white chocolate in a couple of the smaller molds.
I think the small chocolates would be really cute on top of cupcakes, if I can keep Blaze from eating them faster than I can make them.
