crazing slow cooker

HI Clayarters,

I purchased a Rival Slow Cooker with the glazed ceramic insert. Happily
made some soup and after the third use, was surprised to find grease on =
the
surface of the metal interior where the heater is. After emptying the =
pot
of the soup saw that the glaze had crazed both inside and outside and
somehow the hot oil from the beef seeped through the whole pot. =20

I took a digital of the pot before I cleaned it showing the craze =
marking
and wrote to Rival. Their response was less than satisfactory, not
responding to the complaint unless I could show my sales slip. Somehow, =
I
had lost it so gave up pursuing the situation. What I am writing about =
is
to ask if anyone has had similar problems with their slow cooker ceramic
insert. Do you think that it would be possible to fire the pot at =
perhaps
Cone 9 in my regular firing? I know these things blow up occasionally
especially if they have been used or contain dampness in the clay body =
under
the glaze.

This was no big monetary loss but I sure looked forward to having supper
ready when I came up from the studio. =20

Regards,

Bonnie Staffel

Hi Bonnie,

I can't answer your query about refiring the liner, but I would probably never
buy another Rival appliance and I would look for a slow cooker at a garage sale
this summer. They seem to show up in garage and rummage sales often, like
exercise bicycles, aka glorified clothes racks.

Best,
Bonnie the CPA

Hello Bonnie:

I used mine a few times, it shows no crazing as far as I can see, but it
shows metal marks from, stirring I guess. Doesn't that make it too soft a
glaze??

I would not put it in my kiln if i were you especially since it apparently
seeped oil through it to the metal container. Can you imagine the mess in
the kiln if it blows up.

Take care and enjoy food made the old fashioned way:)

Hi Bonnie,

My Dad had made a wooden lid for a big ole crock he had and not figuring on
the expansion of a swelling naked wood lid it cracked this really big crock
, so He wanted me to fix it... He nagged me for 20 yrs about this thing
and never thru it away !!! Well I finally got a chance to visit him up in
Maine a few yrs ago where I had time to just BE WITH HIM . So out to the
automotive store for some JB WELD .... I got the over nite stuff not
the 5 min stuff. or JB QUICK. It heats to 500 degrees F so I'll bet it
does ok in a crock pot heater unit.
I cant remember what my Dad uses his for but I am thinking he makes sour
crout or something wet. I applied to the crack which was visible left it
over nite and then filled the pot with water.... it still leaked some but I
found some other parts that needed the JB Weld and applied more. It took
a few times to find all the cracks but That baby is almost as good as new.
Just has a few mob related scars

My bet is if you can figure out where the cracking is and can apply some
JB WELD to these areas ( I did inside and outside for sanitary reasons and
for added strength and told my Dad to whittle down that tight fitting lid
He was a machinist by trade so I figure he made a perfect FIT
without taking into concideration the materials he used. ( raw pine ) ....
Hope that helps Momma B.... your pal Cat

I just happened to be reading Clayart Bonnie...,,,,,,,,,
I was asked to make a ceramic lid for a Rival Crockpot
years ago and foolishly agreed. They have those wierd plastic ones.
The two pieces were fired
again to cone 6 and seemed ok cept the lid was a tad small.

I have no idea about c 9.

Reynolds has been advertising a new product, a crock pot liner, which is a
disposable sheath that you cook in, then throw away, thus saving you from
scrubbing cooked on chili off the crock. Sounds like these liners would
solve your problem, and bee cool too :-)

Kathy, the one thing specifically I liked about the slow cooker was that it
had a nice glass lid bound by a metal edge. It also was oval and very nice
looking. A friend offered me her liner but hers was round so wouldn't fit.
I am very concerned about the heating system as my food was boiling on low
heat. I think I will write to Rival and then ditch the darned thing. May
not even be safe for lampworking annealing.

Regards and thank you,

Bonnie Staffel

Pam, I also saw that advertisement. However, I am against using plastic for
cooking as well as aluminum. Since I feel the heating unit is also faulty,
it may not be a good idea to use the darned thing at all. I will write the
snail letter and may even do the 800 number. Thanks for that solution.
