Also, the name Vulcan Forge is also in use by other businesses- a google will turn that up. There's a "Vulcan's Forge" that seems to also design jewelry

Some of you may think i'm being nit-picky. But I personally look at these things in different ways than others do because I know that these sorts of things can be potential problems. It's a lot better to take care of all of this up front, as the business is getting going, than down the road. Lawsuits and having to totally change the name of an established business will cost a lot of money and headache.
