So what I used was food grade silicone. There are many brands who have different names for it.
There are different grades, cures, durometers, (how flexible it is)pot life, (how long you have to work with before it cures)
So you must double check each products specifications.
The main difference is that food grade silicone is non toxic and is platinum cured versus tin cured.
The specific product I used was Smooth on Sil 940, sampler size.

It's 2 lbs and about 40 bucks. But it's easily enough to do a few molds. The kit comes with complete instructions and there is a phone tech support in case you get lost.
Just googling "food grade silicone" will find you what your looking for.
Here is the same product, different company, on ebay:

Find some place near you that sells it, Tap plastics will be carrying it soon.
You will need the following materials:
-Han Solo in Carbonite toy
-Foamcore (it's usually white paper with a foam core)
-Glue gun with a few sticks
(Big tip here, you can use Legos instead of the foamcore/gluegun method, I'll explain later)
-Food grade silicone ( if you ever wish to use food products in the mold, otherwise regular silicone will work)
-Baking chocolate
I watched all of the videos available on Tap plastics website before I even started. I suggest you do the same to make the process full proof :) Especially on mold making!

Remember you can cast any object. And if you can cast any object you can mold anything into chocolate!
Someone out there is already working on a battle of hoth scene in chocolate. Complete with chocolate AT-ATs and powdered sugar for snow!

Signing UpStep 1: Building your box mold.
Or even cooler you can use your old Legos to make a box mold.
Here is a link with the basics.

I however had my Legos maliciously taken away from me at a very early age so I'll be using foamcore.
First using your glue-gun, glue your object to be molded onto a flat foam core peice. You want to create a seal all around the base of the object so silicone does not flow under the object.
Using the glue gun then glue a box around the object leaving a quarter of an inch to a half inch all the way around. This will make the mold strong and less prone to warping.
The particular food grade silicone, the Smooth sil 940 is easy to mix. I just poured the complete bottle into the silicone tub.
However each silicone is different. Double check your silicones instructions.
'Pouring silicone'
You're going to pour in your silicone. Best way is to start at a corner and let the silicone flow in/onto the mold and not pour directly on the mold. This helps reduce bubbles.
Let it cure for 24 hours then you remove the cured silicone from the foamcore box mold.
It's going to need post curing in a oven but use the instructions for your specific silicone product.

I want one of those kits so badly!
Second Part: I've seen one at Techshop, but have lived in envy of those who have them.
The chocolate looks great. If you are really interested in continuing your work with chocolate bars you should learn how to temper chocolate! It helps your chocolate keep its "snap" after it has cooled, and it also allows it to set at room temp in 5 minutes as opposed to a few hours in the fridge. If you want some tips just let me know!
Nice to have an eatable 'ible!
