Not all casting media are food-safe, which is why you need to take extra care in choosing your mold-making resin if the treats you make are intended to be gobbled up by others. Smooth-on suggests Equinox 38 for any food-grade mold-making and the results are intricate as they are impressive. A tutorial on their site gives the run-down on how it’s done.
A support form is made for the piece to be molded (they used a coin) and the resin is mixed to be impressed.

Chocolate is poured in and left to cool, before being devoured by the nearest lucky person. As you can see, the quality of the mold is excellent.

This gives you plenty of time to cast some Halloween treats. Smooth-on also suggests making molds of:
custom shaped hard candy, chocolate, gummi bears, gelatin, marzipan, cheese, nougat, poured sugar, gum paste, shaped rice, bento box shaped food, royal icing, pastillage, ice cream, pate, edible cake decorations, dessert motifs, ice, fondant, butter and more!










Timely stuff. We made a mold of a pig’s head… chocolate piggy, anyone?
I was wanting to re-use pop bottles and plastic milk jugs to create molds by vacuum forming. I was wanting to make candy/chocolate molds. Didn’t work. Both are blow molded, and shrink when heated. Know of any food safe plastics that could be re-used for vacuum forming?
I am just finishing up a huge batch of marzipan I made for my local burningman decompression (shaped like the man effigy!)… I first tried the green-label silicone sealant from the hardware store (once its cured its food safe, its what they use for aquariums I think), but it was hard to work with. I think I could figure out an easy method eventually but then I moved on to instamorph, a moldable biodegradable plastic. The key is that its reusable… the silicone compounds are permanent, and can get expensive if you need to scale up (e.g. for chocolate which needs time to set). Instamorph is kinda rigid though, and it messed up my linoleum floor, but its nice stuff once you get the hang of it. Im in love.
I had not heard about InstaMorph before, it’s really interesting. However the website says that while non toxic, it hasn’t been certified as food safe. I think it’s mostly a matter of cost – the certification is surely very costly… – but it would be nice to have this additional safety.
