Rebecca, that kiln has kiln wash on the shelf already. No need for more. You won't be using the shelf for beads. Get a mandrel rest for inside the kiln to put your finished beads on.

Many suppliers have this rest available. Once the sticky is gone from the bead you can move the bead off the rest and onto the floor of the kiln. I usually keep about 3-4 beads on the rest at a time. Some colors like rubino should always stay on the rest since they stay sticky at around 950.
Firing up the kiln and holding at around 200-250 might dry it out but I think you are ok either way. Call me and we can see what is already pre-programed and usable. Or you can just try to fire up the kiln and see how it does. Babysit it for the first firing. Don't turn on and leave the room.You got a fair deal on that kiln! Enjoy!
