When I was a kid I used to cast figurines using plaster-of-paris (gypsum?) in rubber molds, things like ashtrays, ornaments etc.
Plaster-of-paris is the same stuff they use as a cast for broken limbs.
I suspect the environment the items are intended for would have a large bearing on what to use since plaster-of-paris wouldn't last long outdoors even if it was sealed somehow.
For outdoor use or harsh environments you might even consider using an epoxy as a casting material because that would be resistant to just about anything but darned expensive for large items.
