I am very fortunate to be teaching a class on hot and cold patinas for the Boulder Metalsmithing Association on October 18th at Tinkermill in Longmont, Colorado.  These are the same patinas I use on my copper jewelry and the leaves of my floral vessels.  Students will get to try several patinas and even take home samples to try with their own work!
