While I'm scoffing my sandwiches, a couple questions, if I may?

How do you polish metals? I'm guessing it's more complicated than a spot of Brasso on a rag? I'm thinking copper, brass and nickel-silver. I'm also guessing I'll need some sort of machine to do it – maybe one of those Minicraft tools with a buffer?

Also, if I wanted to enamel some parts of my 'jewellery' could I used cold enamel – is it as durable as fired enamel?

I'm probably going to have quite a few newbie questions over the next few weeks, so please bare with me!

Thanks, Steve
