This is what I bought inside, a frozen block of teal-coloured water. The wax I'd used to seal the jar had melted and/or disintegrated at some point and the remnants were trapped in the ice, you can even see some on top. I set it aside for a few days so that the ice had time to melt and I could find time to clean up my mess.
|Failed verdigris experiment. A frozen mass of copper acetate, copper piping, vinegar, wax and water.|
The answer, not much. Just a disgusting combination of sediment, teal-colouring, wax and soggy dead bugs. Definitely nothing useable.

The good news it that for my next foray into making verdigris I have purchased organic vinegar's (unfiltered apple cider with "the Mother" and a white wine vinegar) which attempts to get me a small step closer to what would have been available in period. I've also been donated some homemade wines so that I can attempt to create my own vinegar.
Experiments are pending.
