I have gotten on this site several times and searched for this topic, but not found anything. I have recently become the owner of a Skutt Kilnmaster 822. I am excited to have a kiln but very green. I got a special deal in that the the kiln was ALMOST new and I got full warranty. The included shelves have kiln wash on them, but the person who used the kiln (supposedly only once) before I got it got a little glaze on one of the shelves and it looks like they possibly just put kiln wash over the glaze. I have some kiln wash that was given to me. I have a few questions regarding the shelves and kiln wash:
1. Do I need to try to remove the small amount of glaze on the shelf and, if so, do I use a sharp chisel or possibly a rotary tool?
2. Should I put on more kiln wash and if so, do I first somehow take off the kiln wash that is on the shelf or do I just put on another coat?
3. I got a couple of new shelves and put a couple of coats of kiln wash on them. I think maybe I did not get on enough. I have fired the kiln with the newly coated kiln wash. Is it ok to just add another coat before using it again?
