Hello! I have some questions about kiln shelf care and storage.
— After my first glaze fire, some dark grit was left on the shelf surrounding some of my pieces. I’ll try to attach a picture. What is this? Should I scrape/sand it off?
— I kiln-washed the shelves and fired them before firing any ware, per Skutt’s instructions. Going forward, what’s the best way to use kiln wash? I know when it gets old and flaky, you can scrape it off and reapply. Do you just re-wash the shelves, put ware on top, and bisque/glaze fire as usual? Or do the washed shelves need to be fired again before putt
