I'm in the midst of preparing things for tomorrow's Market in Edinburgh (still a lot on my TO DO list, snap!), and in the meantime carrying out mysterious and smelly experiments - I have no aspirations to turn metals into gold, but discovering a perfect verdigris patina formula would be neat!
Currently trying out the apple cider vinegar and salt solution - I guess it's more suitable for larger pieces, as it didn't turn out that nice on small ones, but maybe it's just me, being crappy chemist...
