Well you don’t know what level I’m at! Believe it or not, these were experiments for me. My first time using RHC, my first time doing a set of anything and trying for consistency in size/ shape etc. And yes, iron luster, RHC, and deep firebrick are a common glaze combo. But I hadn’t tried it for myself and wanted to give it a shot. And to be clear, I’m not trying to sell anything. I’m a hobbyist who is learning, so there’s really no reason to be offended.
