spindy Posted December 2, 2014 Report Share Posted December 2, 2014 We Fired a load of greenware and the kiln sitter did not go off. We lost a few pieces that melted. The bisque is yellowed. Most are nativity pieces which will be under glazed and some will be glazed. Is it worth the time to paint. I am not sure how hot it went to. Thank you!

Mark C. Posted December 3, 2014 Report Share Posted December 3, 2014 You will have a hard time applying glaze-heat the pieces 1st so they are warm and glaze will stick better. Yellow bisque ware is a bear to work with. Mark Link to comment Share on other sites More sharing options...
neilestrick Posted December 3, 2014 Report Share Posted December 3, 2014 Like Mark said, it's going to be a real bear to get the glaze to adhere. It may be faster to remake the work. Does your sitter have a backup timer? Link to comment Share on other sites More sharing options...
spindy Posted December 3, 2014 Author Report Share Posted December 3, 2014 Thank you. That's what I was afraid of. We are new to this and I set the timer to long. I also had the tall cones in the peep hole,but just saw the bright orange color. The cones are old would that be the problem or is the sitter need calibrated.

neilestrick Posted December 3, 2014 Report Share Posted December 3, 2014 Cones don't wear out, as long as they have stayed dry. The sitter may be out of calibration, or it may simply have stuck. It happens. The timer should be set to no more than 1/2 hour longer than the expected firing time. That means you'll have to do a couple of firings to figure it out. Always turn up the kiln on the same schedule so you have consistency. And even then you should always be there to check that the kiln shut off properly. I have seen both cones and timers fail at the same time. Link to comment Share on other sites More sharing options...
Marcia Selsor Posted December 3, 2014 Report Share Posted December 3, 2014 Possibly you need to reset the kiln sitter. You need a small flat head screw driver. Set the lever weight in place using a fresh cone. Have the "claw" from the sitter holding up the lever so that the weight is held up by a 1/16 of an inch. That will drop the weight to shut off the kiln when the cone bends. You can get a little disc that sits on the inside of the kiln on the sitter to set it correctly.

Marcia Selsor Posted December 3, 2014 Report Share Posted December 3, 2014 You may try setting the claw with less than a 1/16" just to be on the safe side. The set screw is on the lever with the weight. Over time, the weight can slip, not allowing the melted cone to release.Make sure the rod supporting the cone can move freely and doesn't get hung up.

Crusty Posted December 3, 2014 Report Share Posted December 3, 2014 get a pack of 022 small cones to test your sitter with - I know its a cone you may never use for anything else but it can always be your sitter adjustment pack.. you want a 90 degree bend, then your good to go.. you also want kiln wash on the bottom 2 rests and the rod tip, Not on the white tube that comes through your kiln... I just did my kiln a few weeks ago, the 022 is low heat and it wont crank your electric bill up to bad... Link to comment Share on other sites More sharing options...
neilestrick Posted December 4, 2014 Report Share Posted December 4, 2014 Make sure it's a very thin layer of wash. Too thick and it will affect the function of the sitter. Link to comment Share on other sites More sharing options...
Babs Posted December 5, 2014 Report Share Posted December 5, 2014 Was A post some time ago re. where to position cones for best visibility.Also a log of how lonfg your firings are taking gives you a great guide as to when it should be 'drop' time for hte sitter.
