Inside the box

I decided to go down the same arty route as the last box, but with a little extra.  I liked the green patina that I got from the Copper sulphate in the last box, so I added a layer on the bottom of the box, painting a solution onto the inner surface and heating it with a heat gun to get the green finish.

I thought I'd make an insert for the box which fuses metal with the wooden platform. My first attempt resulted in disaster as just as I got the metal box into it's wooden housing, the wood shattered.
The picture below is the second version, using a different type of wood and a smaller copper box.

So, with the insert in place, this is what the box looks like now...

And to give an idea of how it looks opening and closing...
