I'm wondering why you are firing it twice? If you're not adding glaze,
oxides or surface treatment between firings, why the bisque then the final
firing? I have a 33 inch tall sculpture made in two press molds with paper
clay & I'm planning to fire it once to cone 8. Any words of wisdom will be

Joy- I can't speak for anybody else but I'm too cheap to fire twice. Except
for the occasional functional piece that is.
I just take things rrrreeeaaaalllllyy ssssloooww. I candle for 8 to 14 hours
depending on the building method and thickness then up slowly from there.
I use commercial glazes to 04 and some plain 5 when the fit takes me. I've
had bad luck with low fire amaco gloss and other low fire gloss bubbling
doing this though. Matts are fine. And so are the ^5.
I've been stumbling along on my own until last year when I went back to
school and also found clayart. So my methods may be madness. ;^)
