2013 Verdigris Experiment

I've started a new verdigris experiment.  This time I'm trying out three different vinegars to see the different vinegars will effect color and amount of verdigris created.  Last year I only used the Distilled White Vinegar, so I'll be comparing with what I get at the end with what I got last year.

This year I have used: Apple Cider Vinegar (Unfiltered, 5% acid), Wine Vinegar (5% acid), Distilled White Vinegar (5% acid)

I'm using copper pipe sleeves to grow the  verdigris on.  Glass jars are so I can watch and photo the process and plastic conectors are being used to hold the copper sleeves out of the vinegars.

April 30th - Right after the Jars are sealed.

 8.5 Hours Later:
There is Verdigris grown on all the copper tubes.
Apple Cider Vinegar looks to have the most verdigris
Wine Vinegar is a close second, but it's darker
White Vinegar, copper is dull looking with green spots

8.5 Hours later, Verdigris growth can already be seen.

 End of Week 1:
Apple Cider Vinegar - Completely covered in Verdigris, has the lightest colored verdigris
Wine Vinegar - A few bits of copper can still be seen, darkest colored verdigris
White Vinegar - small areas of copper can still be seen

End of Week 1.
