The process is simple. Cut an oblong piece of glass in your required size and then grind all the edges smooth (with a glass grinder). Then surround your glass with copper foil - this is the catalyst for your solder to adhere to. Cover in solder, soldering on some decorative pieces of silver wire, solder on a wire ring for the chain and voila! your pendant is complete. You can also add beads to dangle from the bottom section, a nice creative touch.
