I am hoping that someone could let me know what is going wrong with my cast?
I have attempted to cast this ring around 5 or 6 times now and I always end up with the same result.
Since I took these pictures I have made the pour hole as large as the widest part of the ring and have tried adding an air vent in the opposite end of the ring, but the result is the same.
This is my first attempt at casting anything using delft clay after watching all of the At The Bench videos.
I am using plenty of borax and I make sure to heat the silver for around 30 seconds after it goes like mercury. I also make sure to keep the heat on the metal as I am pouring it in.
Any advise would be appreciated.
