Hey @liambesawdon't know why I read that oval kiln post this go round...but...I would consider Rectangle shelves and utilizing the empty space of the oval for tall things like that birdbath stem.
I got a 27inch tall space right next to my upward burner, stuck a 16in vase there the other day, came out like 4 tone, fading up in melt. Really dope.
@Mark C. There won't be any "filling the shop" with these! Lol! They call big Bonsai trees 2 man or 4 hand trees, I call this "Four Hand Barbie".
