Ok,i cured the blue in water for a whole day in my 50 watt qasar lamp. Then cast at
350 for 2 hours
875 for 1.5
Then 1400 for 4 hours, extended it 1 hour. I was getting good before but these were all but perfect. I think that extra hour finishes the burn. I also vacuumed the flask. The detail is better with the blue i find.

Anything bad looking is investment. No porosity, no voids.

Those look great Len! Yes, we now recommend longer burnout on the high end, which obviously depends on the type of oven you have. With electric ovens that makes all the difference.

So you held it at 1400 for 5 hours total and then dropped to casting temp?

Also, what investment did you use? I'm definitely going to try this burnout.
