to re-fire to the original cone number, here cone 6, i try to put things in the bottom which is the cool spot. you can see that there is only one row of element down there, the bottom shelf has 2 sets of posts, 2 inch for the half shelf and 41/2 for the next full shelf. i know the firing evens out at the end but somehow i just feel better knowing there is a slower rise at the bottom. this kiln load was mixed with re-fire pieces and glazed greenware throughout. nothing bad happened to anything.
