Everyone must be using 1/2 Oz boards because I mixed up a batch as stated, kept it heated to 74 deg F, and it took 4.5 HOURS to finish a 1" x 6" 3 Oz board! By finish it was a pretty green, and the next board took 6+ HOURS even with agitation and sponge wiping! Either I can't read or you all use micro thin copper. I did try a new batch with 1/2 Oz copper, and a 1" x 1" piece still took a half hour with constant agitation. Doesn't stain so that is nice, but I could have CARVED the boards with a jacknife in that time!
