Casting in house but achieve that

It seems that rings didn't cure well. Try to cure prints in different directions.

Too much water in investment??? How long did you let flask sit before putting in oven? What investment? Top temp of 1350 degrees for at least 3 hours?

Looks like general deterioration due to insufficient curing versus something like ash from incomplete burnout.

Weak investment at the hard edges could be a problem too. I'd rather let it sit for 6 hours before burnout. However, some people have had success with faster investment cure times. I wonder if it is really magic.
