Also, it sounds like something may be wrong with the carbon. Even if I don't get nice patina, I still don't get black pieces. It's important to clean the carbon from ash after every firing and to refresh it once in a while. Also, I do suspect that there are some bad batches of carbon. Hi Debbie,

I fired at your requirements and it just looked black, and then lowered the temp to 1520 and shortened the hold time to 2 1/2 hrs. That time it looked black with some patina. It sounds like I'm heading in the right direction. Any ideas? I’m getting closer, but my pcs are more black and less patina than yours.

I take the box out with a fork as soon as the chamber as not red hot anymore (around 1000F). I remove the lid with cross-lock tweezers and let the box cool some, until I can touch it with a glove without burning the glove. When I pour the carbon into the sieve some of it is glowing red. This is not safe practice, though! Be extra careful and don't do it indoors. Much higher. I take the box out with a fork as soon as the chamber as not red hot anymore (around 1000F).

Does the kiln read 300, 400, 600... when you take out the box? So how hot are we talking? Does the kiln read 300, 400, 600… when you take out the box?
