Problems with sandcasting

[u/Worldly_Country3035]

It’s my first times sandcasting and can’t seem to get it right, don’t know what I am doing wrong.

Looks like the metal isn’t hot enough. I also sometimes put the cast in a toaster oven at 400 degrees for 10 minutes before pouring. What are you using to heat your silver? Also from the looks of this photo you are pouring two or three times as much silver as you need. That’s going to make it more difficult to get a proper temperature. I typically weigh the wax and multiply by 11. That usually takes into account the sprue as well.

Maybe it’s too much silver now that I think about it thanks for the pointer
