We have fairly good success firing copper reds using stoneware as the
claybody... we bisque fire to ^06 and then glaze fire to ^9/10.... during
the glaze fire (gas kiln) I go into reduction around ^015 about 800 degrees
Celsius, "oxyprobe" around .67 and I stay in reduction at that same reading
until I reach ^9/10.. I then shut the kiln down and immediately close the
damper, cover the burner ports, peeps in, etc... close it up "tight" and
let the kiln COOL SLOWLY for about 60 hours prior to opening the kiln... I
would never consider firing without using an oxyprobe. ...Marshall
