Making Mokume Gane

I have been experimenting in making Mokume Gane. This is one of my first rings, this was made from copper and sterling silver and was commissioned by a gent in in the middle east. I love mking this stuff, i really like the way the pattern reveals ists self as you sand the ring to shape. I am trying to master making Mokume in a kiln but i am finding it hard to source some of the sundery parts in the process. I do a google and you find a dozen sites in the States who sell exactly what you need but none in the UK, I know its out there its just a question of finiding it and finding what they call it here.
