This silicone beeswax mold is for making 5 x 1oz bars of beewax at a time. For accurate weigh, put the mold on a scale prior to pouring and tare the scale (zero out the weight of the mold on the scale). As the wax cools it will shrink slightly making it easy to release without the use of any mold release. These molds are a great way to store and sell your own wax!
