Acid test!

Despite having a self-prescribed sanity break from the studio I just had to have a little play ...I actually popped this piece in the acid to see if there was any life left - I thought the old ferric might have lost its juice - and promptly forgot about it for two days! It etched beautifully over this extended time so I guess the acid is on its way out but at least I was able to recover this! The last thing I forgot in the acid was a brass washer and it disappeared completely!
