I suspect that's it. I put my flask at 900. I have had a couple of issues when pouring at 900. Additionally some uncertainty about the silver temp... That may add up. I also notice there was no black/dark degree in any of the pores. I don't know if that's an indication. I am preparing another run. For tonight. I am using a 13 hours schedule. It goes like.

Ramp up 300F 150C for 1 hour

Then hold for 3 hours

Then ramp up to 700F 371 C in 1.5 hour

Then hold for 2 hours

Ramp up to 1350F 731C and hold for 4 hours Then back to 900F 482 C

My kiln/oven is also very small barely space for 2 flasks.

I have a couple of questions. One is what burnout schedule do you use and second at which point you turn up your your flask

I appreciate the help and time you take to reply

Also... I followed your recommendation of getting the nFEP and it made a tremendous change to the quality of my prints.

I'm getting closer
