I learned some more things about casting the EpoxaCast 690. On one of the last pieces it was really opaque:

I called Smooth-On the next day and asked about it. They didn’t know, so I figured I needed some new stuff and ordered some. When I got home from work that day, I decided to microwave the Part A and this made it start to become clear again. So, apparently it is rather sensitive to temperature, and it being 50-55F in my garage wasn’t good for it. I warmed it up in front of my powder coating oven and the next casting was clear.
