That's really interesting! I like the smooth surface finish on the petrobond, but I agree the coal dust sand looks nicer. Here I thought the petrobond couldn't handle iron temps. I get the same flames from bronze castings with the stuff.
@JCSalomon

IIRC, petrobond can indeed handle cast-iron temperatures. Once. I hope to be corrected by folks with practical experience, but I believe Cu alloys just burn the oil out of petrobond, and the whole sand (even the “burned” black bits) can be reused, though eventually you need to add more oil. In contrast, iron temperatures will actually damage the petroclay adjacent to the casting.

I think I like the rougher texture of the coal dust rather than the dull smooth texture of the petrobond. Cast iron castings have always had that rougher texture and it makes it look true to being cast iron, the smoother texture is usually for bronze imo, and just doesnt look right. I was about to yell at the screen when you cut into the flywheel and destroyed it...
@luckygen1001

Petrobond sand did not give a smooth surface all over so looks strange. Also I agree cast iron needs to have that rough texture to look like older castings. You need to sacrifice a casting now and then to produce better castings in the future.
