Drop Ring Mold

I made my own drop ring mold with Kaiser Lee Board and rested that on top of kiln bricks. I made a 5 1/4" square piece--that I ended up fusing too long. The edges dog-eared. But I used it on the drop ring mold anyway. Then I lost control of the drop! I looked, it was sagging slightly...I waited 10 minutes and it was sagged like this.

I was expecting mediocre things when I opened the kiln this morning. I was pleasantly surprised! I like it. I'd like one better that I control more. But I really like this. I can't wait to make more!
