I am using 2 layers. The shelf – well how flat is flat is a good question which I took up with Paragon. When a 17″ straight edge is layed on the shelf you cal slip 2 thickness of letter paper under it at the middle. So the shelf is not perfectly flat. But is that not flat enough? So I am in the prcoess of turning the shelf to test on the other side.

Paragon could not guarantee that a new shelf would be any flatter so credited me with the price of a shelf. Personally I would rather have a working kiln. This one is un-useable unless I can solve this problem. Unfortunatly finding a 17″ square shelf that is not Paragon is like finding hen’s teeth!!
