Sometimes the shape you want to duplicate cannot be placed into a mold box to make the mold. Here we show you a brush-on mold making process using the re-usable mold making material, ComposiMold. The rose pattern was found on the back of a plastic chair and we wanted to make a chocolate from it.
So first we cleaned the chair well before placing a thin layer of ComposiMold over the shape. If necessary, use touch of vegetable oil as a mold release. The ComposiMold is melted in the microwave using the direction on the label.
The process for the brush-on mold making technique works by building up successive layers. Each layer cools prior to putting on the next layer. To make it go faster, let the ComposiMold cool so it is thicker before pouring or brushing onto your shape.
The thickness of your mold depends on what you are molding. For larger molds, build up a thicker mold to provide additional strength. The mold can also be backed up with more ComposiMold after it has been removed from your master shape.
With this Brush-on technique, you can make molds of objects hanging on walls or even upside down. The best approach for these more complex placements, is to keep the ComposiMold closer to its melting temperature of 130 F. This way the ComposiMold will be thicker and won’t drip as much.
For this rose mold, we built up approximately ¼ inch of ComposiMold. The ComposiMold mold is now carefully pulled off of the master shape on the chair. Any extra ComposiMold can be re-melted and re-used for your next mold.
The mold is now ready for casting. We used a white chocolate to make the flower.
