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