Review on DAS Hardening Modeling Pound 387500 by Gelin Battle

I am planning a special project that will be exhibited. I studied air dry clays online. I've tried a few that ripped. The most positive reviews concerned DAS. I tried. I kneaded it into manageable balls until soft. I kept my hands wet. I added water when it seemed a bit dry but not too much. I used almost the entire 2.2 lb block. I built a simple 10" conical man with an aluminum foil head. It was covered with 1/8 - 3/4 inch DAS - different thickness. I've read that clay that is air dried will crack if dried too quickly. I cut holes in a large zipper lock and left it open at the bottom. It dries slowly over two days, loosely covered. Then I removed the bag and let it dry for about 24 hours. Ideal! rock hard! It can be sanded down. Absolutely no cracks. Dried white. I love that tone. I wonder what will happen if I just let it air dry without the zip pocket. Maybe I'll keep experimenting. I'm ready to start my project with the right tone!
