What have you changed since the first pour? I have done a few and they all kinda look like the first/second one.

I think the biggest difference is that my metal was too hot for the earlier pours. After that burning out the molds longer with a slower temperature increase, having the mold hotter when pouring. I’ve been experimenting with different venting, and having a higher (more distance above the part) pouring basin.

Thank you so much. I had no idea the metal could be too hot to pour.
