About this kiln - Are you saying that you had full round shelves mixed with
half shelves??? That's not good practice.


The thinking is that full round shelves block heat transfer where half roun=
allow better heat transfer. Loading with half rounds, spaced to not be on
plane with another, is thought to promote more even firing. There may be
other reasons I am unaware of.

In my kilns, I use a full round for the bottom (which is still lower than
the lowest element in my kiln), and halves the rest of the way. When I firs=
started firing I used whatever, where ever, but changed after reading enoug=
Clayart posts and instruction manuals promoting the better heat transfer
