Firstly, thank you for your reply I appreciate it. We have been using a cone 5 cone for the glaze fire however we should be using witness cones as well for a more accurate read. So far the cones have folded over pretty evenly on top and bottom possibly a little over? As for glaze application we’ve had a fair mix of under, just right, and over glazes. We’re finding that some of ours are pretty runny. To get into reduction we have pretty much just been closing the flu and waiting to see the orange/red flames peeking out. To be entirely honest I am not confident with how to do it correctly. We are working on test tiles though so we can accurately gauge which colors are most changed through the reduction firing in the future.
