This morning, I happened across a yummy piece of chocolate in polymer clay, from Perlenküche.
That's realistic enough to make your mouth water, if you're a chocolate-lover.
One difference I see between it and the real thing (also pictured in the blog entry) is the lower sheen in the clay piece. If desired, a slight shine is easily achieved with a light buffing with a denim rag. However, the more matte finish of the polymer chocolate looks like a lot of real chocolate I've seen. (As usual, it comes down to personal preference.)
The accuracy of the stamped brand name is great, and the edges look just like a tab of chocolate broken off a bar. (Boy, I sure hope any chocoholics who see this have a stash to break into. After looking at those photos, you're probably going to need it!)
Every now and then, I notice photos of polymer clay chocolates from my contacts on Flickr. If you're looking for more chocolatey clay goodies to drool over, Flickr and other photo-hosting sites are good places to search for decadent creations-- both dollhouse scale and larger (frequently worked into jewelry).
