I'm casting again today, and this time the slip was less viscous. I used exactly the same amount of deflocculant, but I also threw yesterday's bad castings into the mix. I drained the molds after 15 minutes, and soon I'll begin opening them. If the castings are like the last group, I'll let them dry overnight in the molds.
