Buy a postal scale. They're accurate and widely available.

I will post my results as soon as I've finished with the various tests. Right now the company offers several standard sizes, the largest of which is 20" square and costs $195 retail. I believe that custom sizes are available, but they're not cheap. The product is about 1" thick, one side is smooth, ...

You can just use cheesecloth to smooth by hand, or if you want something really smooth than use a buffer attached to a regular drill (or just a car buffer without the cerium).

I'll report more when I'm finished with my testing.

If you want your scraps to fuse together in the bottom of your mold, then you will need to fire higher than 1250/1300 F. Try around 1450/1500 F (800C). This should work, but make sure you have a good coat of kiln wash on your mold.
