I just bisqued the vase yesterday. It almost took a whole kiln. I managed to put to trays on the bottom. It comes through the bisque. Now glazing. I am not crazy about spraying, but may have no choice here. I will see what is a clearance of the bucket for the width of the vase. I was loading the kiln today for Sunday firing, and am not loading this vase for this kiln. I will have a time to think about.
I’m not keen on spraying either, I think its difficult to tell the thickness of a glaze if you’re not actually using your hands to do it. Sometimes it can be too thick when you thought it was a thin coating and other times too thin when you thought it was thick!
Good luck, hope all goes well!
