I work in a studio where there are a number of potters, and recently one did a
cone 5 firing, and I unwittingly bisqued my most recent 2 loads before a show,
-paper clay cone 10 - work and didn't know he had done the cone 5 firing.
Suprisingly most of the pots turned out ok. I used lowfire commercial glazes
which went on quite well, and luster fired some and raku fired the others, and
they all turned out fairly well. Those that had multiple firings actually
turned out the best, as the overlap of glazes turned out to be very
interesting. Only one of the raku pieces actually broke. I expected quite a
bit more breakage with the raku, but I did fire up quite slowly. Patricia

Today was "cooler" some clouds in the sky and I made my raku firing. For the test I
added to the fire ( the first session) some ^6 glazed paperclay wares. I choose of
course these I did not care so much about.
The result: Two that had thin walls survived good one with thicker walls broke a little.
I do not see any advantage of firing to ^6 and refiring to raku, perhaps you might get a
stronger body. In this case you should applied before the first ^6 firing a glaze that will
be crackled at ^6 - perhaps John and Ron's Glaze 5# High expansion (from "The
Book" page 80). If the glaze is durable it will stay in one piece.
My conclusion: If your ^6 glaze turns out afoul and you don't want to dump it cover it
with another glaze and refire to ^6.
Lichen and crawling glazes, all over or partly, will do the job!
