05 October 2014 - 03:18 PM

I am planning the make gingerbread houses from Laguna electric brown cone 6 clay body. I want to use a white slip for the icing. The slip needs to be thicker than normal,,,,I think.

Any suggestions?


Adding Refractory Insulation To Outside Of 2.5 Inch Kiln Wall

25 September 2014 - 12:18 AM

My gas conversion kiln has a 2.5 inch wall so I'm burning a lot of extra gas because of the thin walls. I want to make an outer insulating layer that would be 3-4 inch thick to improve firing, slow cooling by reducing heat loss.

I have fire clay and perlite. Do I need to add mullite or a calcium aluminate cement; or can I use a different type cement in my homemade castable?

I have read over and over again not to use portland cement because it spalls and and sometimes explodes. Is this still true for the outer insulating layer?

Kast-o-lyte costs $116 for 55lb bag mullite is slightly less.

Any suggestions?


Stacking Help For Reduction Gas Firing

15 September 2014 - 03:15 PM

I am looking for literature on how stack gas kilns for even reduction firing. I need education about how to use bag walls and stacking to direct the flame through a kiln.


Learning Reduction In My Conversion Kiln

13 September 2014 - 01:00 AM

I unloaded my kiln conversion kiln this AM. I still have lot to learn, but I wanted to show off a little.

This is my first piece using my homemade O2 sensor to control reduction.

What do you think?


Oxymeter Reading During Reduction

11 September 2014 - 02:52 PM

I am 3 hours into firing my small gas conversion. My homemade oxymeter is reading 27.1 mvolts. The damper is open 1 inch and there is the smell of reduction in the air. There is an orange glow in the kiln.

What range of readings (in mvolts) represents light,medium, or heavy reduction?
