Verdigris Pigment

I finally found some time to scrape off the verdigris from the copper pipe sleeves.  After the scrapping and grinding, I ended up with 2 grams of pigment.  I'm not looking at starting another round of verdigris in a few weeks, using several different vinegars and even a homemade vinegar to see what colors and how well they produce.

Pigments

My handout for a class on pigments is almost done being written.  I needed some pictures of actually mixing a pigment to paint, so this past weekend I sat down and did just that.  I've added these pictures to my pigment page here.
