Silicon moulds are frequently used for small runs of jewellery. I had several silver castings made this way of an Eagle Claw. You could contact a silversmith, or perhaps the appropriate part of a Polytechnic. (Craft School)
Major makers of silicon moulding materials, (Dow, ICI?) may be able to help.
No. They will melt into cake.
They melt it and pour it into molds and let them cool and harden.
Melt chocolate and pour over it
when u frost a warm cake, the cake absorbs the icing making the icing soak into the cake which will make your cake nasty and stiff...
melt the logs and make a cake base
If you frost a hot cake, the heat from the cake will melt your frosting. You should allow the cake to cool completely before frosting. Cake is delicious warm; if you aren't planning on frosting it, it's perfectly fine to serve the cake before it cools. Allowing a cake to sit and cool for a bit also helps the cake to hold together better.
No, silicon isn't a liquid - unless it's really hot. Like about 1420 °C, or 2577 °F. That's the melting point of silicon. It has to be really hot to melt.
no sorry you have to make a glaze
of course the icing then wont melt
It's not something just anyone can do. You'd need a lot of time, plastics, some sort of molds, and way to melt the plastic into the molds. Not so much of a DIY project.
High because you make cakes with it so it wont melt
Yes! I teach cake decorating and chocolate buttercream icing on french vanilla cake is delicious
