Tumbler for silver plated wire wraps?

[radioactivesquirrel]

Hi,

I'm a newbie to jewellery making. I've got some 0.8mm, 1mm silver plated copper wire which I've been using to wire wrap sea glass. Whilst I'm not only finding I'm marking the wire with my pliers which working with it which annoys the heck out of me I'm also worried that the wire is still quite soft after it's a 'finished' piece. I'm not up to doing the wire wrapping where you make intricate designs - I've attached an example of the first pendant I've tried so you can see what I mean. The tendrils are still soft and easily moved. I'd like them to be solid. So, could I put the whole thing safely in a tumbler? I'd love to get to use sterling silver wire but I'm not sure if the extra cost warrants what I'm doing with it?

Hope that all makes sense! Thanks in advance.
