There's nothing "seemingly" about Thorley shelves being defective. There's a major problem with cracking. Fortunately, Laguna credited me for the last dozen 13 x 26 x 1" cordierite's I bought. I see now that my choice is to go to Advancers, but $4000 to reshelve the kiln? Yeah right.
I must say I envy Lee, having someone collecting used silicon carbide shelves and delivering them cheap to Mashiko! WOW!
