These 2 glazes are the same recipe, same firing and same shelf in the kiln, however the one on the left was glazed after I made a new batch with a bag of RIO that was noticeably lighter in color than the previous bag. The recipe uses only 3% RIO. I happen to like the new glaze better, but I'm curious how this will affect my other glazes. I tested Chris Wolff Plum and was hoping to make a full batch for my next firing. It uses 11.5% RIO. Any thoughts?
