Thata some looking greensand. I make my own start to finish, classify pure silica sand, powder bentonite clay mix wet and mull it, greensand should hardly leave any grains on your hand when its properly made wet and mulled. Grains all over the hand usually means too wet or not mulled properly. I do 2 part molds for plastic injection machines and get a near perfect face, i just do a light lap on flat sandpaper (it has to be an immaculate face to seal) so for anyone wondering- it is possible to get incredible accuracy and detail with good green sand/delft clay.

It doesn't apply on this part. If u pound ur sand into dang near dust add little clay. Cheap kitty litter works for diy.. ur casting will be whole bunches smoother. Less grinding... Machining the part. Who cares if it's smooth right. Also helps keep big pit holes in casting.. sure u know. Putting it out there for who don't. Peace
