Firing Error And Bloating

31 August 2014 - 08:17 PM

After 175 ^04 and ^6 firings I had my first incomplete firing. According to the controller info, this small SPS Crucible kiln either had a low voltage issue or problem with the elements. It got to 2166 F before the error aborted the firing.

I attempted to do a full on test to examine the elements but will have to come back later when it is dark so I can see the elements more easily. The night after the firing (last night) we had a wide area blackout from some unknown (to me) problems. So, I am wondering if the kiln issue was related to an impending obvious voltage problem. Much to check on. I am also tempted to just do another ^6 firing and see if all is OK now.

Meanwhile, I am wondering if the horrific bloating on the one large planter in that firing is the result, and if I should take a chance on re firing it. It went through a slow bisque with good results, but wonder why it bloated so much. The whole piece is bellowed, and there are 30 or so bloats from the size of a marble to a grade a large egg. This is Klamath Brown 634 clay-- first time using it. If I retire, could it explode from the bloats?

Anyone Familiar With A Randall Extruder?

16 April 2014 - 01:58 PM

I have tried unsuccessfully to find out about them online. I have the opportunity to purchase one, perhaps with a part missing, so I need to know whether parts are available, and if it is a decent one. I haven't seen the extruder yet.

Any comments appreciated.

Firing Recycled Commercial Ware

18 October 2013 - 05:33 PM

Someone approached me looking to rent my crucible kiln to fire commercial ware. I am trying to look at pros and cons, and also prevent harming my kiln.

The ware is usually white glazed. To this, decals are added. Then they seen to be fired 04/05

I am not Leary of the decals. It is not knowing the clay body and what it was previously glazed with. I also have concern that "non toxic" paint might be used to further decorate it.

PRO: $$$
CON: The aforementioned worries-- Are they justified ?

Thanks in advance for your replies.
