Hi Folks, Been following this thread. I haven't had a piece blow up in =
years. I
refire pieces, sometimes two or three times =5Bespecially multicolor sandy =

glazes.=5D Eventually I get something I like, or the piece breaks. =5BIt's =
only
mud...=5D I agree with the writers who suggest using a cool brick or shelf =
under
the piece. Also, there is no law stating that you MUST turn the burner on =
full,
and fire as fast as possible. I usually candle for four or five minutes, =
then
put the burner sort of medium-high for another 5 min, THEN let 'er rip. =
Haven't
done any really thick sculptures yet, but if/when I do, I'll fire even more

and smoking are what count.

I agree totally with firing slower-- it can be done--we used to bump up the
gas every 15 min with the entire process taking up to an hour longer-- never
lost a pot.Where I'm firing now frowns on a slow raku -saying that its not
real raku--whatever. Needless to say we lose pots !!

Hi Folks, Been following this thread. I haven't had a piece blow up in

refire pieces, sometimes two or three times [especially multicolor sandy

glazes.] Eventually I get something I like, or the piece breaks. [It's only
mud...] I agree with the writers who suggest using a cool brick or shelf

slowly. The amount of time taken to reach temperature is not what causes
the
various raku effects; thermal shock, reduction [both during and after
firing,]
and smoking are what count.
