Dear Clayart,
My kiln fired up to only 840c yesterday, which should have been a 1000c =
bisque. Being forever hopeful the poor old Dagny will make each firing, =
I let her run her fist usual 12 hours, saw that she was only at 730c, =
and let her run another 4 hours, finally giving up hope when she was at =
840c after 16hrs. Most people with electric fire bisque in about 8 =
hours I believe, but Dagny needs at least 10, sometimes 12. She is 35 =
years old and is 260 ltrs.
I was prepared to unload the bisque not really bisqued, thinking I would =
be very much behind now with having to rebisque once the kiln is =
renewed. However, even though according to the cone table, I only =
reached cone 12, my ware is quite pink and looks only a tiny shade =
lighter than my usual bisqueware. Using the delightful tongue test, I =
must say the pots from this failed firing grab a little more than the =
usual, but not a huge difference in stick.
Question: Do I need to rebisque, or can I get away with being careful =
to slightly dilute my glazes before using them on these wares and get a =
decent result?
Of course the kiln has orders in it and one important one: an urn =
already 5 years overdue. (Not because of me, but long story on family's =
side): I would appreciate any prompt answers, greatly.
Best regards,
Alisa in Denmark
I was trying to keep busy not to think about the failed firing, so all =
the Swans and ducks and their young are swimming heavily tonight. I =
also visited the puppy we are going to adopt in July. Cutesville.

Alisa,
One thing you have to watch out for on under-bisqued ware is that if you use
tongs to dip your piece in glaze, it is easy to poke a hole in the pot!
Otherwise, all you need to do is hold your pot in the glaze maybe 1 - 2
seconds LESS THAN you normally would. The purpose of bisquing is only to
make the ware hard enough to handle, and RR would also add that bisquing
burns out the nasties that cause bloating in some bodies. (But not MINE, of
course.....that's caused by water, & salt.....bwahahahahahahahahaha.)
Sounds like you could use a new set of elements.
